基于东方财富网股吧中单只股票的股评信息采用文本挖掘法建立个股投资者情绪指数,探讨个股投资者情绪与股票收益率的关系,并进一步探讨市值大小不同、行业不同以及市态不同的情况下个股投资者情绪与股票收益率关系的异质性.实证结果表明:个股投资者情绪对股票收益率存在着显著的正向影响且影响周期较短,股票收益率也会引起个股投资者情绪正向变动但具有一定的时滞;公司流通市值越大,个股投资者情绪和股票收益率的相互影响程度越小;个股投资者情绪与不同行业股票收益率变动的关系存在异质性,行业内竞争程度越高,个股投资者情绪与股票收益率变
旅游型城镇三生空间协调发展问题备受业界关注,以典型旅游型城镇二道白河镇为例,构建耦合协调度评价模型,分析时序演变规律,对比灰色GM(1.1)模型、三次指数平滑法(ES)及GM-ES
Let G be a nonempty closed subset of a Banach space X.Let B(X)be the family of nonempty bounded closed subsets of X endowed with the Hausdorff distance and BG(X)={A∈B(X):A∩G=φ},where the closure is taken in the metric space(B(X),H).For x∈X and

We present some improvements of the Li-Yau heat kernel estimate on a Riemannian man-ifold with Ricci curvature bounded below.As a consequence we prove a gradien
假设薛定谔算子L=-△+V中的非负位势函数V属于反向Hölder函数类RHs(n/2≤s<n),我们给出了Riesz变换Tα,β-Vα▽L-β的Hardy型估计.这个结论实质性地推广了已知结果.
Assume thatτis a finite dimensional complex Lie superalgebra with a non-degenerate super-symmetric invariant bilinear form,p is a finite dimensional complex super vector space with a nondegenerate super-symmetric bilinear form,and v:τ→osp(p)is a homomorph
By the new spectrum originated from the single-valued extension property,we give the necessary and sufficient conditions for a bounded linear operator defined on a Banach space for which property(ω)holds.Meanwhile,the relationship between hypercyclic prop
Define the differential operators φn for n∈N inductively by φ1[f](z)=f(z)and φn+1[f](z)=f(z)φn[f](z)+d/daφn[f](z).For a positive integer k≥2 and a positive number δ,let F be the family of functions f
介绍了电磁学中库仑(Coulomb)定律和麦克斯韦(Maxwell)方程组建立的历史过程.通过对Coulomb定律的建立和完善过程的分析,阐释了建立一个物理定律需要经历的步骤,对学生科学思维的培养具有一定促进意义;通过对Maxwell方程组建立过程的讨论,阐明了物理定律的层次性和科学美学观念,对激发学生学习兴趣有一定的积极作用.
