A duoethnographic exploration of colonialism in the cultural layer of the objective psyche
Journal of Analytical Psychology, Volume 68, Issue 1, Page 27-47, February 2023., 2023 Abstract Using a duoethnological approach, supported by Jung’s theory of archetypes and the layered objective psyche, the paper demonstrates how a duoethnological encounter can lead to new formulations of archetypal theory that challenge attitudes to diversity.

Review of Policy Research, Volume 39, Issue 5, Page 541-569, September 2022., 2022 Abstract Scholarship on boom‐busts cycles in resource extraction often assumes that affected resource‐rich communities are at best reactive, at worst helpless, in the face of the large, exogenous shocks this cycle visits upon them. Researchers infrequently examine what communities themselves can do to improve their economic prospects and residents ...

Does Entrepreneurship Work? Understanding What Policy Entrepreneurs Do and Whether It Matters
Policy Studies Journal, Volume 49, Issue 4, Page 968-991, November 2021., 2021 When a major policy change occurs, policy entrepreneurs—advocates who devote substantial time, energy, and resources to campaigning for a specific policy outcome—are often credited as critical influences. However, there has been a little quantitative, large‐n cross‐sectional study of whether policy entrepreneurship effectuates policy change, how policy

棱锥压头几何形状和试样力学性能对压入径向裂纹萌生的影响 [PDF]
, 2012 仪器化压入测试技术,能够识别材料微区的硬度和力学性能参数,已成为微小尺度力学测试的重要手段。当被测试样为脆性材料时,压入可能在试样表面产生裂纹。压入裂纹萌生是仪器化压入测试技术研究中的关键问题。当测试断裂力学参数(如断裂韧度K_(IC))时,压入裂纹是测试的必要条件,应确保出现;当测试非断裂力学参数(如硬度H、弹性模量E等)时,压入裂纹可能引起测试误差,应避免出现。研究压入裂纹萌生,有助于区分仪器化压入测试中断裂测试和非断裂测试的实验条件,包括压头的选取。压入裂纹的萌生由裂纹驱动应力的强度和分布决定 ...

, 2018 我国页岩气储量丰富, 已探明的页岩气储量居世界首位, 页岩气等非常规能源开发是国家重要培育方向. 但是国内页岩气藏储层呈低孔隙度、低渗透率的物性特征, 需要更有效的水力压裂以改善页岩气在岩石中的渗透性质, 开采难度远大于其他国家. 水力压裂技术难以在页岩中形成大规模的交联裂纹网络, 是我国页岩气开采中存在的基本难题之一. 水力压裂是流-固耦合作用下强非线性的固-液界面问题.

Rare Metals, Volume 45, Issue 10, October 2026.ABSTRACT Laser‐directed energy deposition (L‐DED) offers a flexible route for fabricating γ‐TiAl components, but the as‐deposited microstructure requires post‐processing to overcome limited deformation capability. Here, an L‐DED Ti–48Al–2Cr–2Nb alloy was subjected to solution and solution‐aging treatments.

, 2023 水平井分段压裂是实现页岩气经济开发的关键技术,生产过程压裂裂缝闭合会对开采产生不利影响.由于生产动态数据误差较大且震荡严重,与渗流数学模型内边界条件不匹配,目前很少有基于生产动态数据分析来定量评价压裂液返排与页岩气生产阶段压裂裂缝特征差异的方法.为此,文章提出一种基于反褶积的量化评估返排与生产阶段压裂裂缝特征差异的生产动态数据分析系统新方法.首先,给出返排和生产阶段的渗流模型及其Laplace解.之后,利用压力反褶积算法分别对两阶段的生产动态数据进行归一化处理 ...

Policy Studies Journal, Volume 45, Issue 3, Page 414-441, August 2017., 2017 Well‐resourced and well‐connected individuals, or “policy entrepreneurs,” often play an important role in advocating and securing the adoption of policies. There is a striking lack of inquiry into the ways that social networks shape the ability of these actors to achieve their aims, including the ways in which network ties may channel policy conflict ...
