As shown in the paper, the transition of K value in Japan is extremely stable. There is no increase seen in the United States nor an infection rate convergence due to measures such as the restriction of social activities seen in some European countries. There is no sign of such re-infection. From April 3 to 24, the slope is well approximated by a straight line of -0.0283, and the subsequent trends have also followed the expected line of k = 0.9185. If the situation continues smoothly, it will reach K = 0.05, in mid-May , the level at which declarations of convergence of infection have been issued in many countries.
Figure 3 below shows a straight line fit, the forecast curve obtained from the fit results and the observed values after April 25 . d = 0 corresponds to April 1st and d = 30 corresponds to May 1st.
Samuel Huntington describes the world as Western Europe, Eastern Orthodox Church, Islam, Africa, Latin America, Chinese, Hindu, Buddhist, and Japanese. It is divided into 9 civilizations.
Certainly, Japanese culture is difficult to understand from the outside, and this Huntington theory is intuitively understandable. However, since there are various other countries in the world, there remains a question as to whether it is true or is there numerical support.
Therefore, I decided to make a map using Hofstede’s cultural value to illustrate this situation of Japanese culture’s isolation.
An index for measuring the cultural distance between countries is the Kogut-Shin index. In order to quantify the risk of a company’s overseas expansion, it is defined as follows using the Hofstede’s index.
here,
CDij is the cultural distance between i-country and j-country, Ijk is the i-country k-th Hofstede index Vk is the variance of the k-th Hofstede index
Kogout and Singh have shown that this index correlates with the percentage of joint venture choices that firms make when expanding abroad. However, if the sum of squares is defined as a distance as it is, it does not match the mathematical concept of distance, so it is better to take the square root.
The figure above shows a map of Spain and its neighboring countries using this distance. 31 countries are within the distance of 1 from Spain. In the figure, the Y-axis is an indicator of individualism vs. collectiveism, and the higher the level, the stronger individualism. The X-axis is the perspective related to other indicators, the countries with strong masculinity on the right (countries with gender roles), and the countries with strong femininity on the left.
The map below is drawn around Japan:
This time, Hungary is the only one country within the distance of 1 from Japan.
If you calculate how many countries (or areas) are included in this distance = 1 in the countries or areas where the Hofstede index is measured, it will be as follows:
