Musculoskeletal pain in university students
Background Musculoskeletal pain (MSP) is a leading cause of disability worldwide, yet evidence among young adults remains limited. University students face unique lifestyle risks, including prolonged sedentary study, poor sleep, and excessive screen use. This study aimed to estimate MSP prevalence and burden, compare lifestyle behaviors between students with and without pain, and identify independent predictors of pain occurrence and severity. Me…
Neuroprotective effects of Yizhi decoction via inhibition of Pink1/Parkin-mediated mitophagy in the prefrontal cortex of rats with attention deficit hyperactivity disorder
Can Machines Think Like Humans
As large language model (LLM)-based agents increasingly engage with human society, how well do we understand their prosocial behaviors? We (1) investigate how LLM agents’ prosocial behaviors can be induced by different personas and benchmarked against human behaviors and (2) introduce a social science approach to evaluate LLM agents’ decision-making. We explored how different personas and experimental framings affect these AI agents’ altruistic b…
Computational Basis of Large Language Models’ Decision Making in Social Simulation
Large language models (LLMs) increasingly serve as humanlike decision-making agents in social science and applied settings. These LLM agents are typically assigned humanlike characters and placed in real-life contexts. However, how these characters and contexts shape an LLM’s behavior remains underexplored. In this study the author proposes and tests methods for probing, quantifying, and modifying an LLM’s internal representations in a dictator g…
The mechanism and boundary conditions of farmers’ income increase in financial services
Finance is the core of the modern economy and the bloodline of the real economy; adherence to the people-centered value orientation and the financial services of the real economy as the fundamental purpose is an important connotation of the road of economic development with Chinese characteristics. Financial work is distinctly political and people-oriented, and must consciously practice the concept of the people, serve agricultural and rural deve…
A New Subject-Sensitive Hashing Algorithm Based on Multi-PatchDrop and Swin-Unet for the Integrity Authentication of HRRS Image
Transformer-based subject-sensitive hashing algorithms exhibit good integrity authentication performance and have the potential to ensure the authenticity and convenience of high-resolution remote sensing (HRRS) images. However, the robustness of Transformer-based subject-sensitive hashing is still not ideal. In this paper, we propose a Multi-PatchDrop mechanism to improve the performance of Transformer-based subject-sensitive hashing. The Multi-…

How does social capital influence farmers' adoption of soil testing and formulated fertilisation technology? Evidence from Chinese maize farmers
Exploring the impact and mechanisms of different dimensions of social capital on farmers' adoption of soil testing and formulated fertilisation technology. • Ecological cognition and fertiliser management knowledge have different mediating effects. • Social capital also has limitations in terms of knowledge diffusion effect that should be emphasized. • Cooperatives partially substitute for social capital and functionally overlap with social netwo…
How Do Nonprofits’ Organizational Characteristics Shape Environmental Philanthropy in Texas? A Network Science Approach
In efforts to address the far-reaching effects of climate change and associated impacts in communities, research on environmental philanthropy suggests that more resources are being allocated to environmental societal challenges. However, understandings about which environmental nonprofits benefit from these funding flows is limited. This study integrates resource dependency theory with elitism and pluralism perspectives to analyze a network of e…
Why do some academic articles receive more citations from policy communities
We (1) present the landscape of the citations of Public Administration and Policy (PAP) scholarly articles in policy documents and (2) examine influencing factors along three dimensions: collaborative teams, cross‐disciplinary interactions, and disruptive paradigms. Using data from the 30 most‐cited PAP peer‐reviewed journals and 38,062 documents from 1107 policy institutions, we find that 10.1% of all PAP scholarship receives high citations from…
Covid-19 and Dispute Resolution in China
The COVID-19 pandemic is reshaping the landscape of Chinese dispute resolution. The aim of this article is to outline China's various approaches to such development in times of global pandemic. The article primarily examines the features of online arbitration in China with a special focus on the significance of party autonomy and the authority of the tribunal in handling virtual hearings. This trend prompts the question as to whether virtual hear…
Bridging State and Nonprofit
How are political elites embedded in both civil and political domains? I studied 246 Chinese political elites who also served on nonprofit foundations’ boards from 2011 to 2015 and conceptualized a framework to understand the state-nonprofit relationship before 2015. The political elites can build horizontal connections with foundations, helping the party-state reach nonprofit actors. They can also build vertical connections with political groups…
The Revealed Mechanism of Rock Burst Based on an Innovative Calculation Method of Rock Mass Released Energy
It is very necessary to study the mechanism of rock burst, which is related to the safe construction of many geotechnical projects. Previous studies have shown that small trigger stress will lead to large energy release, but the specific conditions that cause the release and how to quantify the energy are urgent problems to be solved. In this study, an innovative calculation method of rock mass energy release is proposed, and the calculated relea…
How Does an Authoritarian State Co-opt Its Social Scientists Studying Civil Society
What channels can an authoritarian state employ to steer social science research towards topics preferred by the regime? I researched the Chinese coauthor network of civil society studies, examining 14,088 researchers and their peer-reviewed journal articles published between 1998 and 2018. Models with individual and time fixed-effects reveal that scholars at the center of the network closely follow the narratives of the state’s policy plans and …
Computational Social Science for Nonprofit Studies
How can computational social science (CSS) methods be applied in nonprofit and philanthropic studies? This paper summarizes and explains a range of relevant CSS methods from a research design perspective and highlights key applications in our field. We define CSS as a set of computationally intensive empirical methods for data management , concept representation , data analysis , and visualization . What makes the computational methods “social” i…
State power and elite autonomy in a networked civil society
In response to failures of central planning, the Chinese government has experimented not only with free-market trade zones, but with allowing non-profit foundations to operate in a decentralized fashion. A network study shows how these foundations have connected together by sharing board members, in a structural parallel to what is seen in corporations in the United States and Europe. This board interlocking leads to the emergence of an elite gro…
A Century of Nonprofit Studies
This empirical study examines knowledge production between 1925 and 2015 in nonprofit and philanthropic studies from quantitative and thematic perspectives. Quantitative results suggest that scholars in this field have been actively generating a considerable amount of literature and a solid intellectual base for developing this field toward a new discipline. Thematic analyses suggest that knowledge production in this field is also growing in cohe…
