Multiple mechanisms of policy diffusion in China

Public Management Review, 2018
An increased interest in policy diffusion research on China has emerged in recent years. However, the multiple diffusion mechanisms in China have not been explored adequately.

How does public-private collaboration reinvent? A comparative analysis of urban bicycle-sharing policy diffusion in China

, 2020
The public–private collaboration process reinvents itself during policy diffusion. To reveal the cooperative-reinvention process, this study integrates theories of policy reinvention and collaborative governance to develop a framework outlining the ...

Does Policy Diffusion Need Space? Spatializing the Dynamics of Policy Diffusion

Policy Studies Journal, 2017
For decades, scholars in multiple disciplines have examined spatial diffusion, or the spatiotemporal properties associated with the diffusion of innovations. These properties include contagious, hierarchical, and relocation diffusion. Each of these refers to a spatial model that epitomizes how innovations spread among geographic locations.

wd1: Weighted Policy Optimization for Reasoning in Diffusion Language Models

arXiv.org
Improving the reasoning capabilities of diffusion-based large language models (dLLMs) through reinforcement learning (RL) remains an open problem. The intractability of dLLMs likelihood function necessitates approximating the current, old, and reference ...

Diffusion Guidance Is a Controllable Policy Improvement Operator

arXiv.org
At the core of reinforcement learning is the idea of learning beyond the performance in the data. However, scaling such systems has proven notoriously tricky. In contrast, techniques from generative modeling have proven remarkably scalable and are simple

Policy Diffusion and European Public Policy Research

2017
The vast and growing policy diffusion literature analyzes how policy-making in one jurisdiction—be it a country or a subnational unit—is influenced by prior policy decisions in other jurisdictions. Rather surprisingly, Europe remains an understudied area in the recent policy diffusion literature. This comes as a surprise because the European governance

Theories of Policy Diffusion

Comparative Political Studies, 2007
Brazil's democratic constitution granted municipalities responsibility to design and implement social policies, allowing for tailored programs to meet local constituent demands. Yet instead of pursuing local diversity, many governments chose to emulate programs made famous elsewhere. What explains the diffusion of social programs across Brazil?

The Diffusion of Policy Diffusion Research in Political Science

British Journal of Political Science, 2012
Over the past fifty years, top political science journals have published hundreds of articles about policy diffusion. This article reports on network analyses of how the ideas and approaches in these articles have spread both within and across the subfields of American politics, comparative politics and international relations.

The Study of US State Policy Diffusion

, 2020
In 1969, political scientist Jack Walker published “The Diffusion of Innovations among the American States” in the American Political Science Review. “Walker 1969” has since become a cornerstone of political science, packed with ideas, conjectures, and ...

Streaming Flow Policy: Simplifying diffusion/flow-matching policies by treating action trajectories as flow trajectories

arXiv.org
Recent advances in diffusion$/$flow-matching policies have enabled imitation learning of complex, multi-modal action trajectories. However, they are computationally expensive because they sample a trajectory of trajectories: a diffusion$/$flow trajectory
