To forecast the tourism demand across a set of tourist attractions with spatial dependence, a new model is proposed, which has three stages: tourist attraction selection, base predictor generation, and base predictor combination. In stage 1, a method for selecting associated attractions based on multi-dimensional scaling is used to determine the strength of the spatial dependence between each pair of attractions. In stage 2, a hybrid base predictor based on LSTM networks and Autoregressive model is developed, where the LSTM networks are used to capture the spatial dependence among attractions, and the Autoregressive model is used capture the scale of tourist volume at each attraction. In stage 3, a strategy for combining these base predictors is proposed; it can alleviate the overfitting problem of LSTM and improve the stability of forecasts. Finally, the superiority of the model is verified through the data on tourist volumes at 77 attractions in Beijing. [ABSTRACT FROM AUTHOR]

Existing research concerning the relationships between perceived destination restorative qualities (PDRQs) and tourist well-being mainly adopts traditional quantitative methods such as linear regression and structural equation model, and lacks an in-depth discussion on its internal complexity. Anchored in the special period of COVID-19 epidemic prevention and control, this paper takes Qingdao as the research site, establishes a causal-effect model of tourist well-being (hedonic and eudaemonic well-being) by using fuzzy-set qualitative comparative analysis (fsQCA), and incorporates the variable of "crowding perception" to further explore the configuration conditions of tourist well-being. It is found as follows. ➀ The "fascination" dimension achieved the highest consistency among six influencing factors on tourists' hedonic well-being and eudaemonic well-being, demonstrating that it has an important explanatory power to the formation of tourist well-being. However, none of factors alone was able to create the necessary conditions for tourist well-being. ➁ Nine combinations related to high-level of hedonic and eudaemonic well-being are revealed. The core conditions of hedonic well-being and eudaemonic well-being both involve the "mentally away" dimension, indicating that a strong sense of "mentally away" can serve as an important basis for shaping a high-level of well-being for tourists. ➂ The configurations of tourists' hedonic well-being and eudaemonic well-being are significantly heterogeneous. Compared with hedonic well-being, the core conditions in the configurations of eudaemonic well-being are more complexed. ➃ For tourists hedonic well-being and eudaemonic well-being, the combination with the highest consistency "definitely does not include" the high-level of crowding perception. This paper not only deepens the understanding of formation mechanism of tourist well-being, but also provides practical enlightenment for destination marketing and management. [ABSTRACT FROM AUTHOR]

The effect of hydrogen peroxide leaching of silver was studied on the basis of traditional nitric acid leaching of silver from spent silver catalysts. The silver leaching rate was 99.76% by slowly adding hydrogen peroxide in the conditions of 2 mol/L HNO3, leaching temperature 70 °C, leaching time 120 minutes, and solid-liquid ratio 1:4, which had good leaching effect. Hydrogen peroxide oxidizes Ag to Ag2O, which can effectively improve the leaching rate of silver, while the nitrogen oxide produced by the reaction between nitric acid and silver is oxidized by H2O2 to generate nitric acid and continue to participate the reaction. The use of nitric acid hydrogen peroxide as a leaching agent ensures efficient silver leaching, reduces the emission of nitrogen oxides, and provides a theoretical basis and technical support for the green and efficient recovery of spent silver catalysts.

In light of the prevalence of travel conflict between young adult children and their parents, it is critical to examine how conflict can be effectively resolved. A mixed-methods approach was adopted in this study, which used interviews and three experiments to examine how young adult children resolve conflict with their parents and what factors affect their conflict resolution. The results have the following implications. (1) Two main styles of conflict resolution are used by young adult children, namely 'doing what I want' (i.e. self-assertion, persuasion) and 'doing as parents expect' (i.e. self-sacrifice, compliance). (2) The conflict attribution of young adult children affects their selection of resolution styles. (3) The main effect of conflict attribution of young adult children on their resolution styles is mediated by their perspective-taking and moderated by their decision-making power. This paper provides guidance to practitioners on how to manage conflicts in family travel decision-making. [ABSTRACT FROM AUTHOR]
