INTRODUCTIONType 2 diabetes （T2D） is one of the fastest growing medical conditions associated with cognitive dysfunctions. Less attention is paid to the effects of diabetes on task switching （TS）. Switching between tasks is a higher-order cognitive function which is executed through prefrontal cortex. Given that there are brain structural abnormalities （i.e., atrophy in cortical/subcortical gray matter volume and hyperintensities in cerebral white matter）, reduced connectivity between hippocampus and adjacent brain regions （frontal and temporal gyri）,

Space plasmas often possess non-Maxwellian distribution functions which have a significant effect on the plasma waves. When a laser or electron beam passes through a dense plasma, hot low density electron populations can be generated to alter the wave damping/growth rate. In this paper, we present theoretical analysis of the nonlinear Landau damping for Langmuir waves in a plasma where two electron populations are found. The results show a marked difference between the Maxwellian and non-Maxwellian instantaneous damping rates when we employ a non-Maxwellian distribution function called the generalized （r, q） distribution function, which is the generalized form of the kappa and Maxwellian distribution functions. In the limiting case of r = 0 and q→∞, it reduces to the classical Maxwellian distribution function, and when r = 0 and q→k ＋1, it reduces to the kappa distribution function.

从变量的修正补充、模型的应用拓展及政策实践几个方面对托达罗模型的研究现状进行了简要述评,指出现有文献存在一些问题:如使用同一模型解释永久、非永久迁移两种行为决策的不足和引入的非经济收益或成本无法量化。针对我国市民化两阶段特征,指出"农民—农民工"转换阶段为个体短期迁移决策,主要依据城乡预期收入差异,适合运用托达罗模型原型;而"农民工—市民"转换阶段为家庭长期定居决策,主要依据家庭城乡预期净收益差异,且更为重视非经济收益和成本,适合运用拓展的托达罗模型。
