The Effects of Tuition and Student Loan Policies on College Outcomes and Lifetime Earnings

To increase college access and reduce the burden of student loan debt, the US government has developed several new tuition and student loan policies. These include the newly proposed free community college plan and the recently enacted Pay As You Earn plan that makes student loan repayments contingent on earnings. I develop and estimate a dynamic life-cycle model of the decisions individuals make with regard to schooling, work, savings and student loan borrowing. The model is estimated with micro-level US data and is used to evaluate the effects of these educational policies on education outcomes, lifetime earnings and welfare. My results show that the free community college plan benefits individuals from lower-income families the most, increasing their community college enrollment rate by 17 percentage points from 41 percent to 58 percent. However, it reduces the population proportion of individuals who achieve a bachelor\u27s degree by 9 percent. The Pay As You Earn plan reduces labor supply in college, lowers the time it takes to complete a bachelor\u27s degree, and enables individuals to attend higher-quality colleges. The overall education level is improved with the percent of individuals holding a bachelor\u27s degree increasing from 31 to 33 percent. I also evaluate the effects of a hypothetical loan forgiveness plan for college dropouts, which is found to increase college enrollment but reduce college completion. Of the three policies, the Pay As You Earn plan achieves the highest welfare gain and reduces lifetime earnings inequality

Research on Relationship between Knowledge Diffusion Rate and Enterprise Knowledge Search Breadth

From the perspective of patent, this paper constructs a theoretical model between knowledge diffusion rate and enterprise knowledge search breadth, and probes into the relationship between them. At the same time, this paper explores the adjustment functions of these variables including the technical difficulties and the market expectation .Through the analysis of the patent data，we came to the follow conclusions: the diffusion rate of knowledge has a positive effect on the breadth of enterprise knowledge search. The difficulty of technology and the degree of decentralization of innovation sources positively modulate this promotion effect. The market expects this role to be negatively regulated

A Study on the Copyright Law of Live Game Streaming

The growing development of live game streaming industry has given birth to a new industry and brought huge benefits. However, live game streaming is still facing many unresolved intellectual property rights problems. First of all, this paper believes that the game pictures meet the conditions of originality, reproducibility and photography works belonging to the type of work, which can constitute the work in copyright law. The copyright of the work belongs to the game company or the producer, and the live streaming of the game without permission constitutes infringement. Whether the live streaming of the game under different circumstances constitutes fair use needs to use the three-step test method to analyze according to the situation

Impact of technology habitual domain on ambidextrous innovation:Case study of a Chinese high-tech enterprise

To obtain a sustainable competitive advantage in the dynamic environment, it is necessary for Chinese high-tech enterprises to focus on their technology habitual domains in formulating ambidextrous innovation strategy. This study integrates technology habitual domain, exploratory innovation and exploitative innovation within a framework and explores the influence mechanism among them. Based on an in-depth case study on KTE, representing a high-tech enterprise in China, we have several findings. Firstly, we depict the evolution mechanism of technology habitual domain; secondly, we find that the high-tech enterprise’s technology habitual domain will cultivate and develop the firms’ dynamic capabilities; and thirdly, the expansion of technology habitual domain will promote exploitative innovation, while the transformation of technology habitual domain will promote exploratory innovation. These findings can be useful guidance for high-tech enterprises in China who are aiming to achieve ambidextrous innovation to better adapt to the turbulent environment, and thus achieving sustainability

Gut macrobiotic and its metabolic pathways modulate cardiovascular disease

Thousands of microorganisms reside in the human gut, and extensive research has demonstrated the crucial role of the gut microbiota in overall health and maintaining homeostasis. The disruption of microbial populations, known as dysbiosis, can impair the host’s metabolism and contribute to the development of various diseases, including cardiovascular disease (CVD). Furthermore, a growing body of evidence indicates that metabolites produced by the gut microbiota play a significant role in the pathogenesis of cardiovascular disease. These bioactive metabolites, such as short-chain fatty acids (SCFAs), trimethylamine (TMA), trimethylamine N-oxide (TMAO), bile acids (BAs), and lipopolysaccharides (LPS), are implicated in conditions such as hypertension and atherosclerosis. These metabolites impact cardiovascular function through various pathways, such as altering the composition of the gut microbiota and activating specific signaling pathways. Targeting the gut microbiota and their metabolic pathways represents a promising approach for the prevention and treatment of cardiovascular diseases. Intervention strategies, such as probiotic drug delivery and fecal transplantation, can selectively modify the composition of the gut microbiota and enhance its beneficial metabolic functions, ultimately leading to improved cardiovascular outcomes. These interventions hold the potential to reshape the gut microbial community and restore its balance, thereby promoting cardiovascular health. Harnessing the potential of these microbial metabolites through targeted interventions offers a novel avenue for tackling cardiovascular health issues. This manuscript provides an in-depth review of the recent advances in gut microbiota research and its impact on cardiovascular health and offers a promising avenue for tackling cardiovascular health issues through gut microbiome-targeted therapies
