Dynamic Analysis of Sustainable Development of Agritourism Based on Cluster Analysis Algorithm

Agricultural cultural heritage is cultivated by nature and human farming civilization together, and the historical and cultural values it contains still affect the survival and development of human beings; so, it is important to protect agricultural cultural heritage and promote its sustainable development. This paper reviews, collates, and summarizes the research on agricultural cultural heritage and sustainable development of tourism by scholars and experts at home and abroad, and on the basis of relevant theories and with reference to previous research results, adopts hierarchical clustering algorithm to cluster and decompose the attractions preferred by tourists, and then uses the improved density method to search for nearby attractions that meet the requirements in different regions with different search radii, so as to provide tourists with optimal tourism planning and thus provide the optimal tourism planning for tourists. The evaluation index system of sustainable development potential of agricultural cultural heritage tourism is established from four aspects: sustainability of heritage resources, sustainability of tourism environment, sustainability of tourism economy, and sociocultural sustainability. The evaluation index system and evaluation criteria of sustainable development potential of agricultural cultural heritage tourism established in this paper have certain reference value and universality for most agricultural cultural heritage.

On Theory Dependence of Truth in Measurement

Abstract Measurement results are stated in terms of sentences ascribing measured values, as obtained via measurement processes, to measurands, as defined by measuring agents. Since both the definition of the measurands and the characterization of the processes depend on models constructed on the basis of relevant theories, the issue arises of the theory dependence of the truth of those sentences. This paper aims at assessing the question by introducing suitable distinctions about the sense and reference of the terms used to refer to individual and general quantities, in a framework where measurement is construed as an agent-dependent, model-based, purpose-driven activity.

A Study on the Impact of Quantitative Easing Monetary Policy of the United States on China's Economy

This paper studies the impact of US quantitative easing monetary policy on China's economy. In order to cope with the financial crisis in 2008 and walk out of the economic downturn, the United States adopted quantitative easing monetary policy. However, due to the special status of the US dollar as an international currency, although this unconventional monetary policy has injected sufficient liquidity into the world economy, it also has significant negative spillover effects on other countries. On the basis of relevant theories, this paper empirically analyzes the actual impact of the policy on emerging economies represented by China through VAR model. The results show that the policy has a great impact on China's export trade, domestic prices, capital market and monetary policy, among which the impact on China's domestic price level is the largest. But the overall effects are complex, that there is no consistent direction of change, and the volatility is high. Based on the findings, the China government should put more emphasis on the foreign risks when making monetary policies.

Focused Corrective Feedback and Negotiation of Meaning: Students’ Written Language Accuracy and Their Perception

This study is designed to investigate :1) students’ written language accuracy, 2) effectiveness of teacher’s indirect corrective feedback in enhancing students’ written language accuracy, 3) effectiveness of negotiation of meaning during direct peer corrective feedback , and 4) the students’ perception after the implementation of focused corrective feedback and negotiation of meaning. In enhancing students’ written language accuracy, indirect corrective feedback in the form of codes, and peer direct corrective feedback in the form of explanation were applied to 24 students of English Education Faculty (FKIP) of the University of Lampung who took Pre-intermediate writing class. The design was descriptive quantitative. The results demonstrate that ; (1) language accruracy on grammar is considered low but not on vocabulary and spelling, 2) indirect corrective feedback works well only if the students’ have prior linguistic ability, 3) direct corrective feedback works well because peer (s) did negotiation of meaning in forms of clarification , and 4) students have various response during the corrective feedback. The finding was discussed on the basis of relevant theories. Keywords: Focused corrective feedback, indirect and direct corective feedback, negotiation of meaning, written language accuracy, and perception.

Factors Affecting the Cost of Service Trade: Empirical Evidence from China and the European Union

This study examines the factors affecting the cost of service trade between China and the countries of the EU. The costs between China and EU member states from 2005 to 2017 are measured using the improved gravity model. On the basis of relevant theories, the influencing factors system of service trade cost is constructed, and a dynamic panel model is used to conduct empirical analysis. The empirical results can be summarized into four aspects. First, the costs of service trade between China and EU member states has shown a general trend of gradual decline and there is still room for further decline. Second, the costs of trade in services between China and developed EU countries are lower, while those between China and undeveloped EU countries are higher. Third, service restriction, economic development levels and infrastructure have a greater impact on the cost of bilateral trade in services. Lastly, there are differences in influencing factors of service trade cost among countries with different levels of economic development.

Investigating the Impact Factors of the Logistics Service Supply Chain for Sustainable Performance: Focused on Integrators

The overall scale of China’s logistics industry is growing rapidly, and the environment and conditions for its development are constantly improving, which lays a solid foundation for further accelerating the development of the logistics industry. However, logistics services are characterized by subordination, immediacy, demand volatility, and substitutability. Low-level integrated management of logistics services seriously hinders the development of the logistics service supply chain (LSSC) for sustainable performance. Many studies have been limited to the performance evaluation of LSSCs, and the factors affecting LSSC performance have generally been ignored. This study focuses on integrated LSSCs by using an integrator’s opportunistic behavior as the entry point of research and investigates the factors that affect the sustainability of LSSC performance. On the basis of relevant theories, a model for a hypothesis is constructed and eight hypotheses are subsequently proposed. Moreover, 271 survey responses from functional logistics service providers (research object) are utilized to develop a structural equation model for empirical research. Findings show that integrators with opportunistic behavior inhibit the information-sharing behavior of supply chain members. Consequently, the integration capability and agility of LSSCs are reduced, which affects the overall performance of LSSCs. The findings of this study can provide management insights into the behaviors of supply chain members and governments.
