Understanding users’ continued usage intentions for online learning applications is significant for online education. In this paper, we explore a scale to measure users’ usage intentions of online learning applications and empirically investigate the factors that influence users’ continued usage intentions of online learning applications based on 275 participant data. Using the extended Technology Acceptance Model (TAM) and the Structural Equation Modelling (SEM), the results show that males or users off campus are more likely to use online learning applications; that system characteristics (SC), social influence (SI), and perceived ease of use (PEOU) positively affect the perceived usefulness (PU), with coefficients of 0.74, 0.23, and 0.04, which imply that SC is the most significant to the PU of online learning applications; that facilitating conditions (FC) and individual differences (ID) positively affect the PEOU, with coefficients of 0.72 and 0.37, which suggest that FC is more important to the PEOU of online learning applications; and that both PEOU and PU positively affect the behavioral intention (BI), with coefficients of 0.83 and 0.51, which indicate that PEOU is more influential than PU to users’ continued usage intentions of online learning applications. In particular, the output quality, perceived enjoyment, and objective usability are critical to the users’ continued usage intentions of online learning applications. This study contributes to the technology acceptance research field with a fast growing market named online learning applications. Our methods and results would benefit both academics and managers with useful suggestions for research directions and user-centered strategies for the design of online learning applications.
In the paper the authors proved that China’s growth towards dominance in international trade has begun recently, but, on average, the growth of China’s trade volume has doubled every four years over the past three decades. The paper analyses that the rapid growth of the Chinese economy provides all countries around the world especially neigh boring countries, with a chance of interconnected development, which had a decisive impact on the economic prosperity of the world economy at the end of the last and at the beginning of this century. The key priority of Chinese economic policy was called attracting FDI, but gradually it focused on foreign direct investment (FDI) from China. Therefore, the “one belt, one road” initiative has brought maximum effect not only on the country itself, but on the entire global economy, and has become the basis for multilateral economic development. Accordingly, we have come to the conclusion that the project the “one belt, one road” has a goal to strengthen the geopolitical cooperation between Asia and Europe, so it is Ukraine that is important in its implementation. Ukraine is a strategically important logistics hub between Asia and Europe. It is proved that Ukraine is now a promising country in Eastern Europe and has a significant deferred purchasing power potential, which will increase if the political and economic situation in the country stabilizes.
The article is devoted to the Ukrainian-Chinese cooperation in the context of the joint construction of the "Silk Road Economic Belt", in particular, the cost-effective production of renewable energy sources based on agricultural production on the territory of Ukraine with the involvement of investors from China is highlighted. It has been proved that it is advisable to create an agro-industrial park in the agricultural sector, whose activities can be aimed at research and development of new technologies for growing agricultural products and "green technologies" in the field of agriculture. Calculations indicate the possibility of substantiating the quantitative characteristics of biofuel production and the ecological state of the territories. It is shown that in order to identify the degree of influence of these economic and environmental factors on the efficiency of biofuel production enterprises, it is necessary to conduct a systematic assessment of them with the construction of a mechanism for the functioning of such an enterprise as part of an agricultural park, which reflects the relationship of factors of the efficiency of biofuel production. Keywords: The economic belt of the Silk Road, Agricultural Park; Production of renewable energy sources, Production of biofuels, Efficiency of functioning of biofuel production enterprises.
The paper analyzes the mode and method for unstructured information, compares the similarities and differences between ontology and vocabulary and taxonomy, and discusses the position and the function of ontology for unstructured information from the two aspects of standard system of semantic net and the concept characteristic of ontology. Based on the ontologies DB, the annotation of unstructured information is obtained. Information retrieval which consists of concept-matched retrieval and rule-based reasoning retrieval is proposed with the help of information annotation. The experiment results show that rule-based retrieval has better recall and shorter retrieval time than fact-based retrieval and relationship-based retrieval.
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.
