Leveraging an Unhappiness Lens for Smarter Policies
Policy Studies Journal, EarlyView.ABSTRACT Traditional policy research has largely focused on enhancing happiness or well‐being, privileging positive outcomes as the primary metric of success. We argue that a systematic focus on the drivers of unhappiness—rather than solely on happiness—offers a complementary analytical framework that can uncover hidden societal deficits and broaden ...

Jianzhu Gangjiegou Jinzhan, 2020 白浪河无轴式摩天轮采用创新的固定立体环状结构形式,其施工过程中风荷载和温度作用影响显著。为保障结构的施工安全和安装精度,采用非线性分步建模技术对结构施工全过程进行模拟分析;基于模拟结果确定了结构合拢温度和变形预调值,并对结构施工过程和加载过程关键杆件进行监测。结果表明:施工过程中温度作用所引起的结构应力可达60MPa,在分析时应考虑构件安装温度的影响;采用正装迭代法确定结构变形预调值可有效控制结构的最终位形,合理选择合拢温度可降低竣工后结构的应力水平,最大应力降幅达40MPa ...

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

Jianzhu Gangjiegou Jinzhan, 2018 滨海图书馆位于天津滨海新区文化中心,为大跨度连体结构,采用组合钢框架-支撑体系。结构第5层和第6层采用贯通两层的54m跨度的钢桁架相连,该桁架下部无支撑,整体结构竖向构件较少,因此竖向构件承受荷载较大,竖向构件失效将对结构产生重要影响,可能发生整体结构连续倒塌。采用SAP2000有限元软件,以非线性动力拆除构件法为基本分析方法,对结构地下1层与地上1层共44根柱子进行拆除,以分析结构的抗连续倒塌性能。结果表明,分别拆除44根柱子均不会引起结构的连续倒塌,滨海图书馆整体结构抗连续倒塌性能良好。

How Do Policy Narratives Evoke Emotions? An Appraisal‐Theoretic Approach
Policy Studies Journal, EarlyView.ABSTRACT Research on policy narratives acknowledges the crucial role that emotions play within communication and sense‐making. Especially the Narrative Policy Framework (NPF) has placed emotion at the center of attention and stressed that affect‐imbued stories are key for how individuals make sense of the world and navigate through the policy process ...

Jianzhu Gangjiegou Jinzhan, 2006 通过楼板将两种变形特性完全不同的结构体系连接而成混合结构,在受力性能上与框架结构、筒体结构既具有一定的联系,又有本质的区别。本文以一30层外部为钢框架、内部为混凝土核心筒组成的混合结构为例,采用通用有限元程序SAP2000分别计算了钢框架结构、混凝土筒体结构及混合结构,比较了三种结构体系的受力性能;通过调整楼板型式和板厚,探讨了楼板刚度对混合结构受力性能的影响。结果表明,采用混合结构使得结构变形、内力沿高度方向趋于均匀,受力性能得以改善;采用梁板体系能有效地减轻剪力滞后;随着楼板刚度的增加 ...

Journal of Critical Infrastructure Policy, Volume 8, Issue 1, Spring/Summer 2027.ABSTRACT Epistemic orphaning, responsibility drift, loss of institutional memory, and non‐stationarity are not new problems in infrastructure governance—they have accompanied long‐life infrastructure throughout its history. What artificial intelligence changes is not the existence of these problems but their scale, opacity, and the structural ...

Jianzhu Gangjiegou Jinzhan, 2016 近年来,钢结构越来越多地应用于雕塑类等特种结构工程中,此类钢架结构的变形及受力要求高,且为空间受力,结构设计难度增加。以某特种钢结构雕塑为工程背景,利用有限元软件SAP2000建立结构的三维模型,考虑不同荷载工况,对模型进行模态分析,获得其振动模态及其基本自振周期,通过其模态周期来研究结构的整体动力特性。通过分析得到的结构构件应力比和现场采用钢弦式表面应变测量法监测得到的结果均符合规范要求。另外,对下部基础、承台梁、柱及厚板进行分析和设计,并验算基础的抗倾覆能力;钢结构设计中,节点的连接尤为重要 ...

Pollution and Haunted Eco‐Histories: Silent Hill and Silent Horrors in Centralia, Pennsylvania
Popular Culture Review, Volume 37, Issue 2, December 2026.ABSTRACT Centralia is a former mining town and borough in Northeastern Pennsylvania, whose population has been steadily declining since the Mine Fire of 1962—a fire that still burns today. The “horrors” of living in Centralia are reflected in horror media set in postindustrial mining towns like Silent Hill.
