The purpose of this paper is to explore the performance of ridge regression and the random forest model improved by genetic algorithm in predicting the Boston house price data set and conduct a comparative analysis. To achieve it, the data is divided into training set and test set according to the ratio of 70-30. The RidgeCV library is used to select the best regularization parameter for the Ridge regression model, and for the random forest model, the genetic algorithm is used to optimize the model's hyperparameters. The result shows that compared with ridge regression, the random forest model improved by genetic algorithm can perform better in the regression problem of Boston house prices.

Fitzgerald is one of the most important American writers in the 20^th century. The publication of The Great Gatsby shows his great talent in American literature. Eliot, a famous poet and literary critic, once said that it was the first step in the development of the art of the novel since the age of Henry James. Fitzgerald's masterpiece, The Great Gatsby, focuses on Jazz Age New York in the 20th century, depicting the people in the different classes of the society. Besides, love is an eternal theme in literature. And the reality and humanity shown in The Great Gatsby are also of great significance to today's society.

Background: Bitcoin mining, an energy-intensive process, requires significant amounts of electricity, which results in a particularly high carbon footprint from mining operations. In the Republic of Kazakhstan, where a substantial portion of electricity is generated from coal-fired power plants, the carbon footprint of mining operations is particularly high. This article examines the scale of energy consumption by mining farms, assesses their share in the country’s total electricity consumption, and analyzes the carbon footprint associated with bitcoin mining. A comparative analysis with other sectors of the economy, including transportation and industry is provided, along with possible measures to reduce the environmental impact of mining operations. Materials and methods: To assess the impact of bitcoin mining on the carbon footprint in Kazakhstan, electricity consumption from 2016 to 2023, provided by the Bureau of National Statistics of the Republic of Kazakhstan, was used. Data on electricity production from various types of power plants was also analyzed. The Life Cycle Assessment (LCA) methodology was used to analyze the environmental performance of energy systems. CO₂ emissions were estimated based on emission factors for various energy sources. Results: The total electricity consumption in Kazakhstan increased from 74,502 GWh in 2016 to 115,067.6 GWh in 2023. The industrial sector’s electricity consumption remained relatively stable over this period. The consumption by mining farms amounted to 10,346 GWh in 2021. A comparative analysis of CO₂ emissions showed that bitcoin mining has a higher carbon footprint compared to electricity generation from renewable sources, as well as oil refining and car manufacturing. Conclusions: Bitcoin mining has a significant negative impact on the environment of the Republic of Kazakhstan due to high electricity consumption and resulting carbon dioxide emissions. Measures are needed to transition to sustainable energy sources and improve energy efficiency to reduce the environmental footprint of cryptocurrency mining activities.

This study aims to explore the precise characteristics of the issue of bequests, not solely from a jurisprudential perspective as is common among researchers, but also by linking it to its role in community development and progress. Bequests serve multiple functions that represent the ethical and cultural objectives of Sharīʿah [the ‘Divine Legislation’], which manifest in the process of uniting members of a single society. This is achieved through their contribution to building bonds of affection and compassion among individuals. Additionally, bequests have economic dimensions that consider the interests of the needy and provide them with resources to elevate their living standards. The study also presents a comparison between the contract of bequest an inheritance contract in Islamic Sharīʿah and secular laws, particularly Western ones. This is done by examining the mechanisms employed in enforcing bequests and understanding the interests sought in each, highlighting the distinct features of Islamic Sharīʿah in its consideration of kinship and both private and public interests, aiming to clear religious liability and via promoting community development while prioritizing moral and societal values. Accordingly, this study, in its examination of the subject, seeks to investigate the essence and objectives of bequests and extract the meanings endorsed by the majority of scholars who permitted bequests to heirs, conditional upon the consent of the remaining heirs. This approach considers both the significance of maintaining harmonious familial ties, and the positive impact this has on individual and community development. This will then be compared to some methods that strictly define inheritance in certain Western societies. The researcher employed both analytical and comparative methodologies, in line with the study’s requirements, noting that the nature of the research opens horizons for understanding the approaches of non-Islamic countries regarding the issue of wills, the importance of exploring the culture of the other and its foundational references, the impact of Islamic laws on others, and how the laws upon which Islamic legislations were established have benefited from Western legal obligations. This represents an extension that goes beyond legislative codification to a cultural exchange that allows us to build intellectual communication with the other, placing this research before a fundamental problem embodied in the following question: To what extent do bequests contribute to community development? And what are the communicative dimensions that comparative legislation on bequests with the other offers us?

This study examined socio-economic factors affecting Micro, Small, and Medium Enterprises (MSME) e-commerce adoption, focusing on gender, income, and education. Using the 2022 National Socio-Economic Survey (Susenas) data, a logistic regression model was employed to analyze key determinants of e-commerce utilization. Additionally, an online survey of 550 MSMEs across 29 provinces was conducted to assess the impact of digitalization on business performance. In comparison, an offline study of 42 MSMEs with low digital adoption provided insights into the barriers hindering digital transformation. A natural experiment was conducted to evaluate the effectiveness of behavioral interventions in promoting the adoption of e-payments and e-commerce. The main contribution of this study lies in integrating large-scale national survey data with experimental approaches to provide a deeper understanding of digital adoption among MSMEs. Unlike previous studies focusing solely on socio-economic determinants, this research incorporated a digital nudging experiment to examine how targeted incentives influenced e-commerce participation. The findings revealed that digital transformation significantly enhanced MSME performance, particularly in turnover, product volume, customer base, and worker productivity. Socio-economic factors such as gender, household head status, and social media access significantly influenced digital adoption decisions. Behavioral nudging proved effective in increasing MSME participation in e-commerce. Although this study was limited to Susenas 2022 data and survey responses, it bridges a critical research gap by linking socio-economic factors with behavioral interventions in MSME digitalization. The findings offer key insights for policymakers in formulating evidence-based strategies to drive MSME digital transformation and e-commerce growth in Indonesia.

From the perspective of urban school symbiosis, examining the relationship between art universities and their respective cities has pointed out new social service paths for the development of art universities.
