Along with the development of Fintech, many scholars have studied how information technology is applied to financial services with a focus on extended methods for application. Few scholars have studied the influence mechanism behind the adoption of Fintech services. This paper proposes an improved technology acceptance model (TAM) that incorporates user innovativeness, government support, brand image, and perceived risk as determinants of trust to investigate how users adopt Fintech services. We designed a questionnaire, sent it to active customers of the Hefei Science and Technology Rural Commercial Bank, and obtained 387 eligible responses. We analyzed the data with a structural equation model (SEM) to test the hypotheses, including the relationships of all latent variables. The results reveal that users’ trust in Fintech services has a very significant influence on users’ attitudes for adoption. In addition, perceived ease of use and perceived risk does not affect users’ attitudes toward the adoption regarding Fintech services. This study contributes to the literature of the adoption of Fintech services by providing a more comprehensive view of the determinants of users’ attitudes by combining trust of Fintech services with TAM.
To develop sophisticated approaches for distinguishing goji origins, 325 wolfberry fruit samples of a certain cultivar, plant age, drying method, and collection season were gathered from 26 producing areas across Northwest China in 2017 and 2018. We employed 49 indices, including stable isotopes, earth elements, soluble amino acids, and saccharides, to identify the regions of origin of these goji fruits. Analysis of variance (ANOVA) and heritability analysis were used to assess the effects of the environment (producing areas), cultivar, plant age, drying process, and collection season. Samples from the same place can be classified and partially discriminated using principal component analysis (PCA). We were able to distinguish fruits produced in Zhongning County from those produced in the other five producing provinces using orthogonal projection to latent structure-discriminant analysis (OPLS-DA). Calcium (Ca), manganese (Mn), ornithine (Orn), cystine (Cys-Cys), glutamate (Glu), phenylalanine (Phe), phosphoserine (Ps), serine (Ser), lysine (Lys), taurine (Tau), proline (Pro), and tyrosine (Tyr) indices were chosen using S-plots and heritability analysis, and their repeatability was established with samples collected in 2018. The indices selected in this study can distinguish goji berries produced in Zhongning County from fruits originating from five other Provinces with high repeatability, which was validated with various cultivars, drying methods, harvest seasons, and plant ages and with heritability analysis.
An ankle fracture is a fracture of the distal tibia or fibula that forms the ankle joint, usually associated with ligament and soft tissue injury, and is a common type of lower limb fracture and one of the most common types of fracture in the elderly. Although ankle fractures are one of the most common injuries seen by orthopedic trauma surgeons, there is no uniform protocol for the diagnosis and treatment of ankle fractures in the elderly, and there are many controversial indications for surgery. The aim of this study is to assess the clinical efficacy of different internal fixation methods in the treatment of distal fibular fractures in the elderly, in an effort to improve the rational selection and application of clinical acts. A retrospective analysis was performed on 68 cases of patients who suffered an ankle fracture and were treated with different internal fixation methods according to the fracture types and individual differences in distal fibula fractures. The postoperative therapeutic effect assessment was performed in terms of clinical examination, imaging evaluation, and AOFAS ankle-hind foot function scoring. There was no unhealed bone, ankle instability and loose/fractured internal fixation. Fracture healing time was 2.7 to 4.0 months (average 3.2 months). AOFAS score was 88.3 ± 6.2, of which, 34 excellent cases, 30 good cases, and 4 fair cases. Ankle activity dorsiflexion 6º~18º, average 15º; plantar flexion 26º~47º, average 37º. A good clinical efficacy could be achieved from the most appropriate individualized internal fixation for distal fibula fractures of elderly patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
