Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

, 1957 本文首先将以前所得到的关于两个轴对称塑性平面应力问题(薄圆环和旋转盘)的有关方程和计算结果作了一个简单的叙述.这些计算结果是根据两种不同硬化特性的材料和一种理想塑性材料的应力应变曲线在不同载荷下计算得到的.这些结果指出这三种不同材料的应力应变曲线和载荷对于这两个问题的主应力比值和比例应变的影响很小,而对于比例应力的影响则很大.之后,分析了二维的塑性平面应力问题的方程;这些方程考虑了大应变,但不包括体积力(body force).分析这些方程中的包括材料应力应变曲线项和载荷参数项的结果 ...

Vocabulary Strategy Instruction in the Argentine EFL Context: Teachers’ Perspectives and Practices
International Journal of Applied Linguistics, EarlyView.ABSTRACT Despite extensive research on vocabulary strategy instruction (VSI), little has been known about teachers’ perspectives on how it is understood and implemented in practice. This study investigated Argentinian EFL teachers’ priorities in vocabulary instruction, their perceived knowledge of learner strategies for spoken vocabulary, and factors ...

The Effects of Gen‐AI on Situated and Future‐Driven Academic Writing Motivation
International Journal of Applied Linguistics, EarlyView.ABSTRACT Despite the increasing use of Generative Artificial Intelligence (Gen‐AI) in education, there is still a significant gap in understanding its effects on the situated‐ and future‐driven motivation in academic writing. This longitudinal design‐based research sought to explore variations in academic writing motivation of 110 Chinese university ...

Partisanship, Deservingness, and the Attitudinal Policy Feedback Process for Social Policy
Policy Studies Journal, EarlyView.ABSTRACT In an era of identity‐based partisan polarization, we examine whether social policies can still generate positive attitudinal feedback among beneficiaries. Drawing on nationally representative survey data, we demonstrate that partisanship conditions the policy feedback process through divergent perceptions of group deservingness.

Jianzhu Gangjiegou Jinzhan, 2007 冷成型钢截面上的残余应力可能是决定其性能和强度的一个重要因素。通过破坏性的试验方法对残余应力进行测量不仅费时,精度也很有限。本文提出了一个预测压弯成形薄壁截面上残余应力的有限元方法,该方法克服了实验室测量的缺点,提供了一个有力的工具来考察不同的成形参数对残余应力的大小和分布的影响,并因此可以对这些成形参数进行优化。在该方法中,通过解析的方法考虑了成卷和开卷的影响,并将得到的残余应力作为随后的冷弯过程有限元模拟的初始应力。经比较,本文方法的数值结果和实验室实测值吻合很好,证明了该方法的可行性和精度 ...

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

, 2010 在前面我们知道了为什么可能运用加卸载响应比方法做地震预测，加卸载响应比方法不仅有坚实的理论基础，而且为实验室试验、数值计算以及过去的震例检测所证实。那么，在实际运用中，它真的有效吗？ 尹祥础课题组将它用于地震中期预测已经取得了较好的效果，他们成功地预测过一些国内的地震，还成功地预测过一些国外的地震(美国，日本，土耳其等)。下面来看一些用加卸载响应比LURR预报地震成功的实例。 中国大陆： 早在1980年代后期,尹祥础课题组就用加卸载响应比方法对中外逾百个震例,从有感地震的4级～8 ...
