温江绿道建设与乡村旅游发展互馈性分析

文章在实地调查和第二手资料搜集整理的基础上,分析了绿道建设与温江乡村旅游发展之间的互馈作用,以期全面认识绿道建设和乡村旅游发展之间的互促互补关系,为温江乡村旅游发展和绿道规划建设提供理论参考。

组织中的上下级信任

上下级信任除了具备一般人际信任关系的特点外,其在很多方面与一般人际信任不同。首先就是这种关系应剥离成上向信任与下向信任来审视。其次,相同的变量在上向信任与下向信任中的权重与内涵都是不一样的。另外,由于直接上下级在竞争资源上的相似性,跨级信任更容易形成。又由于资源占有的非对称性,上下级信任呈现出非互馈性的特点。

Non-ideal space division multiple access and its application

We study the performance of space division multiple access （SDMA） under a non-ideal engineering situation. When the SDMA channel is of high inter-layer correlation and the condition number is large, the multiple user multiple input and multiple output user equipment （MUMIMOUE） grouping should be optimized, and in some cases further dimension-reduction should be applied. As the channel measuring is always non-ideal, we use two methods, feedback mode and non-feedback mode, in terms of performance and overhead. It is proposed that the non-feedback mode is preferable even for some non-reciprocal channels. Prin- ciple analysis and test results are given.
