New Drain Spacing Formulas Using the Variational Iteration Method

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT In this study, the drain spacing is computed using the variational iteration method (VIM) to the linearized Boussinesq equation. By applying at most two iterations of the VIM method under three different initial condition scenarios, three equations for drain spacing calculation were derived. These equations predict values of drain spacing that

A finite difference method for fractional diffusion equations with Neumann boundary conditions

open access: yesOpen Mathematics, 2015
A finite difference numerical method is investigated for fractional order diffusion problems in one space dimension. The basis of the mathematical model and the numerical approximation is an appropriate extension of the initial values, which incorporates

Direct localized boundary-domain integro-differential formulations for physically nonlinear elasticity of inhomogeneous body

open access: yes, 2005
A static mixed boundary value problem (BVP) of physically nonlinear elasticity for a continuously inhomogeneous body is considered. Using the two-operator Green-Betti formula and the fundamental solution of an auxiliary linear operator, a non-standard ...

Higher-Order Energy Expansions and Spike Locations

open access: yes, 2004
We consider the following singularly perturbed semilinear elliptic problem: (I)\left\{ \begin{array}{l} \epsilon^{2} \Delta u - u + f(u)=0 \ \ \mbox{in} \ \Omega, \\ u>0 \ \ \mbox{in} \ \ \Omega \ \ \mbox{and} \ \frac{\partial u}{\partial \nu}

Between Dependence and Alienation: Understanding the Digital Minimalist Behavior of Chinese Millennials—An Analysis Based on SEM and fsQCA

open access: yesJournal of Adolescence, EarlyView.
ABSTRACT Introduction Following rapid iterations in media technologies, Chinese millennials (born between 1980 and 1995) find themselves in a paradoxical state where digital saturation exists alongside fatigue, making them central practitioners of digital minimalist behavior.

Localized direct boundary-domain integro-differential formulations for incremental elasto-plasticity of inhomogeneous body

open access: yes, 2006
A quasi-static mixed boundary value problem of incremental elasto-plasticity for a continuously inhomogeneous body is considered. Using the two-operator Green–Betti formula and the fundamental solution of a reference homogeneous linear elasticity problem,

Psychological Contracts With Purpose: A Review and Path Forward

open access: yesJournal of Organizational Behavior, EarlyView.
ABSTRACT This review advances the understanding of psychological contracts (PCs) that include third‐party beneficiaries and transcend self‐interested goals, which we term “PCs with purpose.” PC theory has challenged the assumption that social exchange relies solely on balanced rewards and inducements, highlighting that individuals may wish to ...

Fritz Scheffer Under National Socialism: Assessing His Political Involvement

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Aims This article examines the role of soil scientist Fritz Scheffer (1899–1979) under National Socialism and offers a critical assessment of his scientific, institutional, and political positioning between 1933 and 1945. It asks how Scheffer shaped his career within the tension between disciplinary specialization, political expectations, and ...
