Regional News, Regional Bias? Evidence From Media Discourses and Welfare Decisions in Germany

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT How do media representations of immigrants shape their treatment by street‐level bureaucrats? Despite a uniform federal legal framework, decision‐making varies substantially across local welfare offices. Though prior research links national news reporting and policy implementation, little is known about how regional variation in news reporting

Mapping Measurement to Theory in Policy Evolution: A Case of Net Metering Policies of the United States

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT The examination of policy evolution has important practical implications, but current literature often only evaluates changing policy goals and instruments at the macro‐level, overlooking changes that occur at the more granular, micro‐level of policy text.

基因组叠加生物型的基因表达特征

open access: yes, 2000
采用聚丙烯酰胺梯度凝胶电泳及特异性组织化学染色技术分析了鲤、鲫及其基因组叠加的不同组合个体的红细胞SOD. EST和血红蛋白的电泳图谱。结果表明不同基因组组合及不同倍性的个体间存在由基因组差异导致的生化多态性,为不同倍性的鱼类的同工酶(SOD)表达存在基因剂量效应提供了依据,证实了不同组合的SOD亚基间有协同表达、累积作用。研究表明每个基因有其独特的调控机制,因而在杂种三倍体内三分之一的基因组亦能够表达产物。应用本研究的遗传学数据有益于构建基因组特异性品系 ...

苏北地区乙型肝炎病毒基因型分布及临床

open access: yesZhongguo shiyan zhenduanxue, 2008
目的探讨苏北地区慢性乙型肝炎(慢乙肝)患者乙型肝炎病毒(HBV)基因型分布情况及基因型与性别、年龄、疾病分类、HBV-P基因YMDD(YMDD)变异的相关性。方法血清HBV基因型及YMDD变异检测均采用PCR-微板杂交-ELISA法。结果130例患者中基因型B(B型)占3.1%(4/130),基因型C(C型)占50.0%(65/130),基因型非B非C型(NBNC型)占46.9%(61/130)。男、女两组基因型差异未见统计学意义(χ2=1.338,P>0.05)。4例B型均为40岁以下的慢乙肝患者 ...

Environmental Justice in the Brazilian Coastal Food Systems: Policies, Institutions, and Knowledges on Small‐Scale Fishers and Energy Development

open access: yesWorld Food Policy, Volume 12, Issue 2, November 2026.
ABSTRACT This study explores environmental justice issues in coastal food systems, focusing on conflicts between small‐scale fisheries and the energy sector due to differing goals in managing food and energy sources. It does so by examining the interdependence between institutions, policies, and different types of knowledge; key elements in building ...

支气管哮喘儿童的IL-17F基因突变分析

open access: yesZhongguo shiyan zhenduanxue, 2014
目的探讨白细胞介素-17F基因多态性与儿童支气管哮喘的相关性,为支气管哮喘的易感基因筛选提供可能的理论依据。方法取本院门诊随诊的60例哮喘患儿设为哮喘组,60例健康儿童设为对照组,两组儿童均于清晨空腹留取外周静脉血2ml,提取全基因组DNA,应用聚合酶链反应及克隆、基因测序方法分析IL-17F基因序列rs763780(H161R)基因多态性。结果 IL-17F基因序列rs763780(H161R)基因型在两组内均未检测到突变型CC,rs763780(H161R)基因型(TC/TT ...

From Indicator to Prediction: Five Decades of Biochemical Oxygen Demand Research in Tropical Freshwaters

open access: yesWorld Water Policy, Volume 12, Issue 4, November 2026.
ABSTRACT Biochemical oxygen demand (BOD) remains a core indicator of organic pollution in freshwater monitoring, but its role in water policy and practice is changing as water‐quality assessment moves toward predictive, integrative, and decision‐support approaches.

天津地区丙型肝炎病毒基因分型的研究

open access: yesZhongguo shiyan zhenduanxue, 2016
目的研究天津地区丙型肝炎病毒(HCV)基因型的分布。方法收集HCV感染者的HCV基因分型、性别、年龄、临床诊断等临床资料,分析HCV基因型在人群中的分布,以及与临床资料的相关性。结果天津地区最常见的HCV基因型是1b型,占人群比例77.88%;其次是2a型,占人群比例20.07%。在肝炎患者,不同基因型感染者的平均年龄之间存在差异。在肝硬化患者,不同性别的HCV基因型分布存在差异。结论天津地区HCV基因型以1b型最为常见。

Adding the Farmer Domain to Aquifer Recharge: Insights From Smallholder Farmers' Natural Water Retention Measures in the Danube–Tisza Interfluve, Hungary

open access: yesWorld Water Policy, Volume 12, Issue 4, November 2026.
ABSTRACT This paper describes and analyzes recharge practices in Bács‐Kiskun County, Hungary, within what can be categorized as the farmer domain. Such locally embedded aquifer recharge practices remain underexplored in Hungary. Current research and funding largely focus on large‐scale Managed Aquifer Recharge (MAR) interventions emphasizing intended ...
