细胞毒性T 淋巴细胞相关抗原4 基因型与中国南方人群Graves ’ 病的关系
Zhongshan Daxue xuebao. Yixue kexue ban, 2005 【目的】探讨细胞毒性T淋巴细胞相关抗原-4(cytotoxic T lymphocyte associated antigen 4)基因第一外显子A／G(49)多态性与中国南方汉族人群Graves′病的关系。【方法】用PCR-RFLP确定CTLA-4基因第1外显子49位点基因型，分析广东地区汉族人Graves′病患者(GD组)120例及123名正常人(对照组)CTLA-4基因多态性。并把GD患者按性别、家族史、TRAb、突眼等分别分两亚组后分析CTLA-4基因第1外显子A49G位点基因型及等位基因的频率。

Do Criminalization Policies Impact Local Homelessness?
Policy Studies Journal, EarlyView.ABSTRACT Local criminalization policies draw on the logic of deterrence to levy costs on individuals who engage in behaviors that are closely associated with various public concerns, such as those criminalizing behaviors associated with homelessness, thereby potentially reducing community‐level costs.

Topics as Outcomes: Modeling the Influence of Intergovernmental Grants on Policy Diffusion
Policy Studies Journal, EarlyView.ABSTRACT Intergovernmental grants stimulate the diffusion of policy reforms, as the federal government provides states with a financial incentive to adopt policies aligned with federal priorities. Less is known about the extent to which these grants also stimulate horizontal diffusion across states.

Policy Studies Journal, EarlyView.ABSTRACT Based on the Punctuated Equilibrium Theory (PET) and implementation research, this study proposes an extended conceptualization of policy punctuation that enables researchers to systematically include policy implementation as part of a punctuation. The key mechanisms underlying the PET, i.e., policy image and venue, information processing, and
