Development Of China’S Ultra-Precision Equipment Industry And Support Of Patient Capital, Hong Jiang May 2024

Development Of China’S Ultra-Precision Equipment Industry And Support Of Patient Capital, Hong Jiang

Bulletin of Chinese Academy of Sciences (Chinese Version)

As a core field of high-end manufacturing, China’s ultra-precision equipment industry has achieved rapid development driven by policy support and technological advancements. Nevertheless, it still faces challenges such as technological bottlenecks, international competition, and funding shortages. Its characteristics—long R&D cycles, high risks, and substantial capital investments—are misaligned with the risk-averse nature of traditional financial systems, urgently requiring the support of “patient capital”. Although China possesses a vast pool of long-term capital (e.g., social security funds and insurance funds), systemic gaps prevent these funds from being effectively transformed into patient capital that supports frontier technologies. This study argues that developing patient …

Supporting South Korea’S Aging Population: How Ai And Iot Acceptance Connects The Young And Old, Bobby Im May 2024

Supporting South Korea’S Aging Population: How Ai And Iot Acceptance Connects The Young And Old, Bobby Im

Master's Projects and Capstones

In 2024, South Korea surpassed every other nation by becoming the country with the lowest fertility rate (below 0.7%). Population decline will hinder future ability to care for their aging population and although the government and private corporations are investing millions of dollars on developing Artificial Intelligence-Internet of Things (AI-IoT) devices to support the aging, the acceptance levels and the amount of family support required is undervalued. By examining AI-IoT’s current use and role in South Korea’s public health system this paper shows how intergenerational support helps optimize existing procedures and equipment, increases the level of acceptance and use, and …

Impacts Of Atmospheric Rivers On Communities In Northern California: Comparative Analysis Of Sonoma County Hazard Mitigation Plans, Cristina Vance May 2024

Impacts Of Atmospheric Rivers On Communities In Northern California: Comparative Analysis Of Sonoma County Hazard Mitigation Plans, Cristina Vance

Master's Projects and Capstones

Climate change increases the frequency of extreme weather events and affects California’s hydroclimate, thereby increasing flood vulnerability of all communities in Sonoma County. An example of extreme weather phenomena is atmospheric rivers (ARs), which are long narrow water vapor transported by winds across the Pacific Ocean. ARs have a history of causing major flood events that have swept through Sonoma County and negatively impacted cities along the lower Russian River, such as the unincorporated town of Guerneville, California. Major floods cause detrimental impacts to the economy. Social inequalities become evident when unincorporated communities located along floodplains are more vulnerable to …


Does Endogamous Marriage Impact Women's Fertility Gaps In India?, Natalya Francis Schafer May 2024

Does Endogamous Marriage Impact Women's Fertility Gaps In India?, Natalya Francis Schafer

Master's Theses

This study aimed to measure the possible impact endogamous (within-family) marriage practices could have on women's fertility gaps in India. Fertility gap in this study is defined as the difference between the ideal number of children a woman desires and the total number of children born to a woman at time of interview. In many developing countries ,such as India, it is common for women to be overachieving their fertility - having more children than desired. Data from the CIA.gov (2024) shows total fertility rates to be highest in developing areas across Sub-Saharan Africa, the Middle East, and India. The …

Secrets Of The Medicine Cabinet: How Big Pharma's Information Monopoly Influences Federal Public Health Regulations, Kyle James May 2024

Secrets Of The Medicine Cabinet: How Big Pharma's Information Monopoly Influences Federal Public Health Regulations, Kyle James

Culture, Society, and Praxis

Pharmaceutical companies are the largest industry contributor to political activities in the United States. Instead of pursuing traditional routes of political influence, these firms concentrate their efforts within federal public health agencies. By directly intervening in the regulatory process, Big Pharma assumes control of the drug approval process, dictating the means by which pharmaceutical products enter the marketplace. This scheme is designed to strip agencies of their public interest mandate. The resulting political phenomenon, known as regulatory capture, creates a symbiotic relationship where federal agencies and industry mutually benefit from the swift commercialization of drugs. This thesis examines "how" Big …

Immigration Policy Evaluation For Technology Professionals Immigrants In The United States, Angel Contreras Cruz May 2024

Immigration Policy Evaluation For Technology Professionals Immigrants In The United States, Angel Contreras Cruz

Dissertations and Theses

The U.S. Immigration System is complex for technology professionals seeking to relocate to the United States for employment or education. The United States relies on its employment-based immigration to attract and select the best talent to fill the shortage of skilled jobs. Technology professionals, a stream of highly skilled immigrants, tend to contribute and be more beneficial to the U.S. economy, which is one of the principles of U.S. immigration policies. Although U.S. immigration policies are constantly updating, policymakers, experts, and scholars suggest that the United States needs significant immigration reform to solve current issues, such as improving technological capabilities …

An Antisemitism Academia Crisis: Communication Failure On Three Ivy League College Campuses, Rickardo W. Shuzzr

Student Theses and Dissertations

The issue of Antisemitism on college campuses in the United States has gained significant attention following the terrorist attack by Hamas on Israel on October 7th, 2023. This discriminatory behavior, hate speech versus free speech, and academia's role in the geopolitical climate have sparked protests and raised questions about the responsibility of universities today. It has even led to high-profile presidents from institutions such as Harvard, MIT, and UPenn being called to testify before a congressional oversight committee. These university presidents and others have been the subject of ongoing flak in the public sphere. As a result, there have been …

The Effects Of The Tax Credit On The Used Electric Vehicle Market, My Tu T. Tran May 2024

The Effects Of The Tax Credit On The Used Electric Vehicle Market, My Tu T. Tran

Undergraduate Economics Working Paper Series

In the past few years, tax credits have become the fundamental policy instrument to incentivize the adoption of electric vehicles (EVs) in the United States. However, contemporary research primarily focuses on new EVs, while the impact of tax credits on the used EV market remains obscure. This research aims to enhance the knowledge of EV adoption by examining the potential effects of the Used Clean Vehicle Credit, a federal program providing up to $4,000 credit to eligible consumers. We have collected sales data of used cars from 245 CarMax locations in the U.S. between 2021 and 2023 to assess the …
