The butterfly effect in the price of agricultural products: A multidimensional spatial-temporal association mining

With the advent of the era of big data, data mining methods show their powerful information mining ability in various fields, seeking the association information hidden in the data, which is convenient for people to make scientific decisions. This paper analyses the butterfly effect in the agricultural product industry chain from the perspective of producer and consumer by using multidimensional time and space theory and proposes a new price forecasting method. We consider that the price change of agricultural products is not only affected by the balance of market supply and demand but also by the factors of time and space. Taking the pig industry chain of Sichuan Province as an example, this paper explores and excavates the data from 2010 to 2020 in the time dimension. Interestingly, we found that the price changes in pork in the market are generally highly correlated with the prices of slaughtered pigs, piglets a few weeks ago and the prices of multiple feed a few months ago. Based on the precise time-space factors, we improved the price forecasting model, greatly improved the accuracy of price prediction, and proved the effectiveness of multidimensional spatiotemporal association mining. The research in this paper is helpful to establish a brand-new agricultural product price prediction theory, which is of great significance to the development of the agricultural economy and global poverty alleviation.

The Butterfly Effect? Title IX and the USWNT as Catalysts for Global Equal Pay

It is commonly believed that Title IX has had one of the greatest impacts on women and girl’s involvement in sport in the United States and beyond. In 2021, 50 years on from its inception, the development of women’s sport and women’s opportunity within the sporting sphere has increased dramatically. It is doubtless that Title IX has increased participation opportunities and “the question is no longer, ‘can women play?’ The critical question is ‘at what level?’ That’s the 21st century question.”

Analogous Hawking radiation in butterfly effect

We propose that Hawking radiation-like phenomena may be observed in systems that show butterfly effects. Suppose that a classical dynamical system has a Lyapunov exponent \lambda_LλL, and is deterministic and non-thermal (T=0T=0). We argue that, if we quantize this system, the quantum fluctuations may imitate thermal fluctuations with temperature $T _L/2 $ in a semi-classical regime, and it may cause analogous Hawking radiation. We also discuss that our proposal may provide an intuitive explanation of the existence of the bound of chaos proposed by Maldacena, Shenker and Stanford.
