    In a global world, no country, market, or economy is isolated and can function independently. Interconnectivity is a fundamental feature of economic systems, including both traditional financial markets and novel markets. This study aims to explore the relationships between traditional markets and commodities trade. We develop a methodology for analyzing the relationships between five stock market indexes (S&P500, Dow Jones, BSE, Hang Seng, FTSE) and three commodities (crude oil, natural gas, gold), based on multimodal publicly available datasets incorporating structured numerical and unstructured news and social network data. To find the existence of direc tional associations, we develop an Explainable ML model that first learns the dependencies between different assets and then explains them in a form understandable by humans. We apply our methodology to analyze connectivity networks between the assets and discuss our conclusions.

    In this paper we analyze openly available time series data for the prices of 18 cryptocurrencies and 2 stock market indexes (S&P500 and Dow Jones). First, we calculate the correlation values between the cryptocurrencies and indexes datasets. Then, we use a state of the art time series prediction library (XGBoost) in order to make prediction models for the daily prices of all the cryptocurrencies, using the stock market index datasets as input features in the training model. We calculate metrics for the difference between the actual prices and the prices predicted using our models. Finally, we show the feature importance score that our model attributed to each prediction model, and compare the score between the three input features (S&P500 dataset, Dow Jones dataset, and the actual cryptocurrency dataset).

    In today’s rapidly developing, technology driven world, the environment is being polluted in numerous ways, significantly more than in the past. Considering the fact that the fashion industry is the second largest polluter worldwide, it is evident that changes are needed in the way clothing is viewed and used. In this paper, we present a possible solution to this problem, which is built using the constantly advancing concept of shared economy. The platform we present is intended to create an online space that is used to share clothes that are not considered useful by their owners. Furthermore, the rental of expensive clothing for special occasions is provided. Adhering to the importance of the business aspect of any novelty being introduced, a market research was also conducted in our country. This paper includes these results, together with the conclusions drawn and the possible improvements suggested.
