时间银行通常被视为志愿服务的一种新形式,从无偿性维度可将该特殊志愿服务类型定义为低偿志愿服务,以区别于传统的无偿志愿服务。近些年来,部分中国的时间银行开始出现两类志愿服务兼容的混合形态,也就是“混合志愿服务”,并对时间银行的可持续运作产生了积极影响。基于多重制度逻辑视角结合案例分析得出,混合志愿服务主要生成于三种机制:通过时间币分割和分配志愿劳动成果,实现了低偿志愿服务和无偿志愿服务的整合流程设计;建立公益基金专门管理捐赠时间币,实现了两类志愿服务时间币流通的管理制度区隔;另设平台结合基层党建动员党员参与,配合独立的公益基金实现了党员参与无偿志愿服务的组织区隔。在复杂的制度环境中,市场逻辑与公益逻辑相互竞争可能会导致混合志愿服务失灵问题,而政府逻辑的介入以及党建的价值引领与资源整合功能的发挥可以对其进行缓解。

The driven-dissipative Langevin dynamics simulation is used to produce a two-dimensional(2D) dense cloud, which is composed of charged dust particles trapped in a quadratic potential. A 2D mesh grid is built to analyze the center-to-wall dust density. It is found that the local dust density in the outer region relative to that of the inner region is more nonuniform,being consistent with the feature of quadratic potential. The dependences of the global dust density on equilibrium temperature, particle size, confinement strength, and confinement shape are investigated. It is found that the particle size, the confinement strength, and the confinement shape strongly affect the global dust density, while the equilibrium temperature plays a minor effect on it. In the direction where there is a stronger confinement, the dust density gradient is bigger.

批评和自我批评是我们党的优良作风。毛泽东认为，批评就是帮助，自我批评就是“多想自己缺点”,批评和自我批评是一个整体，作为领导者要着重开展自我批评。开展批评和自我批评是由党内矛盾普遍性决定的，是增强党的宗旨意识的必然要求，是增强党的团结的关键环节，是抵制各种政治灰尘和政治微生物对党的肌体侵蚀的有效方法。开展批评和自我批评要全面地辩证地看问题；要从政治上、组织上等原则性的问题着手，发扬民主作风，既尖锐、不讲情面，又遵循“惩前毖后、治病救人”的方针等。毛泽东关于批评和自我批评的重要论述，对今天加强党的作风建设，仍有重要意义。
