House price is closely associated with the development of the national economy and people’s daily life. Understanding the spatial distribution characteristics and influencing factors of the house price is of great practical significance. Although a lot of attention has been paid to modeling the house price from structure and location attributes, limited work has considered the impact of visual attributes. Intuitively, a better visual environment may raise the surrounding house price. When aggregating multiple factors that influence house price, the multiscale geographically weighted regression (MGWR) provides a suitable solution. Specifically, the MGWR assigns each factor a bandwidth to model the spatial heterogeneity, e.g., a factor may have different influences at different places. In this paper, we introduce the visual environment factors into the MGWR method. In detail, we extract ten visual elements, e.g., sky, vegetation, road, from the Baidu street view (BSV) images, using a deep learning framework. We further define six visual environment factors to investigate their influence on house price. Based on the data from two representative Chinese cities, i.e., Beijing and Chongqing, we reveal the influence degree and spatial scale difference of six visual indexes on the house price in two cities. Results show that: (1) the influence intensity of our proposed six visual environment factors on the house price in different regions of the city can be identified, and the green view index (GVI) is the most important visual environmental factor; and (2) the influence of these view indexes changes significantly or even reversely depends on different areas.

Erosion Environment

The Loess Hilly–Gully region (LHGR) is the most serious soil erosion area in the world. For the small watershed with high management in this area, the scientific problem that has been paid attention to in recent years is the impact of the land consolidation project on the erosion environment in the gully region. In this study, the 3D simulation method of vegetation, eroded sediment and pollutant transport was innovated based on the principles of erosion sediment dynamics and similarity theory, and the impacts of GLCP were analyzed on the erosion environment at different scales. The verification results show that the design method and the scale conversion relationship (geometric scale: λl = 100) were reasonable and could simulate the transport process on the complex underlying surface of a small watershed. Compared with untreated watersheds, a significant change was the current flood peak lagging behind the sediment peak. There were two important critical values of GLCP impact on the erosion environment. The erosion transport in HMSW had no change when the proportion was less than 0.85%, and increased obviously when it was greater than 3.3%. The above results have important theoretical and practical significance for watershed simulation and land-use management in HMSW.

Vehicle Market

Exhaust pollution and energy crises are worsening worldwide. China has become the largest motor vehicle producer; thus, promoting the use of new energy vehicles (NEVs) in China has important practical significance. In this paper, considering the limited rationality of governments, NEV enterprises and consumers, we study the subsidy policy of the China NEV market using the evolutionary game and system dynamics (SD) methods. First, a tripartite evolutionary game model is developed and the replicator dynamics equations and Jacobian matrix are obtained. A SD simulation of the model was conducted to further clarify the impact of the initial market proportion and three variables used in the model. The results show that the initial market proportion affects the evolution speed but does not affect the evolution result when the three group players all choose a mixed strategy. For governments, they should not hastily cancel price subsidies provided to consumers; rather, they should dynamically adjust the rate of the subsidy decrease and increase the consumers’ extra cost for purchasing fuel vehicles (FVs). NEV enterprises should appropriately increase their investments in the research and development (R&D) of NEVs.

In this article, we examine the individual predictors that are responsible for accurate beliefs about the link between vaccinations and autism. We then show how these beliefs affect policy preferences about vaccines. We derive two hypotheses from motivated reasoning theory and test these on national survey data from Gallup and CBS News. Republicans were less likely to report accurate beliefs than Democrats. In addition, educational attainment modified the impact of party identification. The gap between Republicans and Democrats in likelihood of reporting accurate beliefs was largest among the most educated portion of the public. Finally, we show that accurate beliefs about vaccines, independent of statistical controls, are important predictors of policy attitudes about unvaccinated children attending public school and parental choice about the decision to vaccinate. We discuss the theoretical and practical significance of these findings.

The monographic approach is used to analyze the dynamics of the actual consumption of agri-food products and the level of food independence for individual agri-food products. Normative and positive approaches are used to highlight real risks and threats to food security. A number of techniques of abstract-logical tools made it possible to make a scientific and applied generalization of the material presented, to formulate intermediate and final conclusions and proposals. Research results. An analytical assessing the impact of the COVID-19 pandemic on the consumption of agri-food products and the level of food independence for individual agri-food products has been carried out. It has been proven that Ukraine produces enough food to ensure healthy nutrition for citizens. It has been determined that due to the low purchasing power of the population, groups of citizens with low incomes have limited access to essential agricultural and food products. In the medium and long term, there will be a shortage of food resources and global food inflation, the situation in agricultural markets will remain unstable, and trade will continue to develop under the influence of not only competition, but also political factors. Scientific novelty. The theoretical and methodological provisions, scientific, methodological and practical approaches to determining the factors of influence of quarantine measures and the spread of COVID-19 to the level of food security of the state have been substantiated. Assessing the impact of quarantine measures and the spread of COVID-19 on food security made it possible to identify the main risks of ensuring the country's food security. Practical significance.

The purpose of the article is to determine with the help of econometric and optimization methods the priority strategies of agrarian business in the field of crop production and to compare with the existing leaders in the use of innovations in the field of crop production. Research methods. The study is based on the use of econometric analysis methods to build trends in grain yield dynamics in leading countries in the use of innovative agricultural technologies and optimization methods for the study of dominant strategies used by agricultural enterprises in crop production. Research results. As a result of using the declining marginal grain yield depending on the amount of costs, which are determined by the cost of importing technology per 1 ha, the optimal cost values for both maximum yield and maximum profit. It is shown that at certain time intervals the costs of farmers were excessively high not only in terms of profit optimization but also to optimize yields. It is assumed that taking into account the latest innovation trends, agribusiness will move to a strategy of profit maximization Scientific novelty. As a result of econometric analysis it is shown that the use as a target function of yield leads to a significant increase in the variability of this indicator, while a moderate increase in yield is accompanied by significantly less variability. Quantitative indicators of the impact of climate risks on grain yields in Ukraine have been obtained, which explain approximately 50% of the variance in the grain yield indicator in Ukraine. Practical significance. It is shown that the representation of marginal yield in the form of a decreasing linear function is confirmed in practice. Further research, which in the presence of detailed information on the production processes of individual enterprises can be conducted by panel regression (observation points are spaced in space and time), can provide a more detailed picture of the efficiency of individual production components in their areas of interaction.

Usability has been an essential component of the Web User Experience (UX) and a focal research topic. In recent years, the penetration of interactive technologies in all aspects of everyday life challenges the way UX is understood and designed. The past decade, Human-Computer Interaction (HCI) scholars have been continuously attempting to introduce and explore new and non-traditional factors in the UX arena, such as aesthetics, emotions, affect, and trust. This study contributes to the field by exploring the relationship between aesthetics and UX; specifically the impact of the classical design element of white space on the perceived attractiveness and perceived usability of an e-commerce website. A between-subject research design involves the manipulation a website’s white space. Three different versions were constructed using 25, 50 and 75% of the white space, respectively. Findings offer support for the relationship between aesthetics and the perceived usability of a website. The study results suggest that the usability of a website is impacted negatively when white space increases over 50%. Practitioners should consider that in the context of eCommerce Web design, reduction of content and shrinking of visual elements, in favor of white space, is likely to negatively impact the usability of a website.
