The Alchemical Oedipus: Re‐Visioning the Myth
Journal of Analytical Psychology, Volume 68, Issue 5, Page 807-827, November 2023., 2023 Abstract The Oedipus myth is foundational to depth psychology due to Freud’s use of Sophocles’ play Oedipus Rex in the creation of psychoanalysis. But analytical psychology’s engagement with the myth has been limited despite the importance Jung also places upon it.

Poverty &Public Policy, Volume 15, Issue 3, Page 290-307, September 2023., 2023 Abstract Aging as a woman within the context of agricultural transformation where production and consumption values shape everyday life raises concerns of later life precarity. Gender economic inclusion is imperative in the achievement of inclusive rural development.

Family Process, Volume 62, Issue 2, Page 557-575, June 2023., 2023 Abstract This is a quasi‐experimental, nonequivalent design study investigating the efficacy of multicouple group and single‐couple intervention formats aimed at diminishing the psychosocial impact of infertility. The review studies carried out to date that have assessed this subject do not show consistent findings and although increasing the efficacy ...

Using online reports of seahorse seizures to track their illegal trade
Conservation Biology, EarlyView.Abstract Illegal wildlife trade (IWT) is a persistent and extensive threat to global biodiversity. Hundreds of marine fish species are subject to regulation under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), but it is unclear how much protection species gain from CITES because information on marine fish ...

A New Finite Element Formulation for Superconvergent Eigenvalue Computation of Wave Equations [PDF]
, 2016 有限元方法是目前结构分析领域应用最为广泛的一种数值方法。自振频率计算作为结构分析中的一个重要内容，可归结为典型的特征值问题，例如：一维波动方程可描述杆结构振动，其特征值为杆结构自振频率；二维波动方程可描述膜结构振动，相应的特征值为膜结构自振频率；三维波动方程可描述声压在空间中的传播，其特征值为声压的振动频率。采用有限元法求解波动方程特征值问题时，质量矩阵的构造方法会直接影响振动频率的计算精度。因而，如何构造可使自振频率有更高收敛阶次及精度的高阶质量矩阵具有重要的研究价值。然而 ...

Dispersive Behaviour of Dual-Petrov-Galerkin Methods for the One-way Wave Equation Comparing with High Order Finite Element Schemes [PDF]
, 2016 MarkAinsworth(2014)曾针对单向流方程，利用高阶有限元方法构造离散波，考察它对于同速情况下的物理波的估计效果。文章不仅给出了详细的分析过程，更是得到了估计相应Floquet因子的相对误差的显性表达式，同时，将其与间断Galerkin方法下的相对误差结果进行了对比。然而，事实证明，无论是高阶有限元方法，还是间断Galerkin方法，它们的估计效果都是具有奇偶特性的。即是说，在多项式阶数为奇数和为偶数时，Floquet因子的相对误差具有不同的表达式，进一步来说，当多项式阶数不断增大时 ...
