From Clueless to Confident: How ChatGPT Transforms Academic Writing in Chinese as a Second Language
International Journal of Applied Linguistics, EarlyView.ABSTRACT Generative artificial intelligence (GenAI) has demonstrated its potential to enhance the quality of second‐language (L2) academic writing. This study used a qualitative approach comprising analysis of ChatGPT usage‐history screenshots, written assignments, and semi‐structured interview data on students’ use of GenAI in their L2 Chinese ...

China's Green Economic Growth and the Corresponding Energy Transformation [PDF]
, 2016 资源耗竭和环境污染已经成为中国可持续发展的严重制约，特别是雾霾等环境问题的大面积集中爆发，更是将这一问题摆在了公众和政府的面前。但是，对于中国这样的发展中大国，“发展是第一要务”，因为解决十三亿人口的吃饭和就业问题都离不开经济较快增长。如何在稳增长、资源节约、环境友好这三者之间的权衡取舍是政府面临的难题。因此，对于中国社会经济的可持续发展，关键是在兼顾经济增长的同时尽可能实现资源节约和环境改善。这就需要实现绿色经济增长的转型。 另一方面，气候目标成为中国经济发展的约束条件 ...

Policy Studies Journal, EarlyView.ABSTRACT What are the conditions under which business corporations expand their institutional power? This paper argues that institutional power is affected by the architecture of the “acquisition regime”—the set of formal (and informal) rules that govern how states purchase public services.

全球能源互联网, 2019 虚拟电厂不仅能够提高可再生能源在电力系统中的接入比例，转变能源结构，也可以通过对储能系统以及对电动汽车和居民可控负荷等需求侧资源的优化调度提高分布式电源的消纳能力。然而，随着虚拟电厂用户侧可再生能源和各种灵活负荷的广泛接入，往往会出现配电系统的线路潮流越限，导致线路发生阻塞，造成事故扩大，影响系统的安全稳定运行。针对此问题，研究了虚拟电厂安全校正优化问题，建立了基于技术型虚拟电厂的配电网阻塞管理模型，并以实际算例验证了该模型的有效性。

Policy Studies Journal, EarlyView.ABSTRACT We use grid‐group cultural theory (CT) to specify underspecified aspects of the Advocacy Coalition Framework (ACF). Our theoretical synthesis of CT and the ACF provides, first, an exhaustive typology of policy actors and their cultural cognitive biases that entail, guide, and constrain policy core beliefs about problem definitions and ...
