企业人力资本引进投资可行性的多层次灰色评价

企业人力资本引进投资是一种高风险性的投资.为了避免投资失误并获得预期的投资效益,企业在引进人力资本之前必须开展投资可行性评价.本文以可行性研究理论为指导,从人力资本质量可行性、企业内部环境可行性和投资效益可行性三个方面建立了企业人力资本引进投资的可行性评价指标体系,并提出了运用多层次灰色评价方法进行企业人力资本引进投资可行性评价的步骤,最后用实例说明了其应用.     

基于熵值法的河北省地级市城镇化质量评价研究

在界定城镇化质量内涵的基础上,从城镇化水平、基本公共服务、基础设施和资源环境四个方面构建了河北省城镇化质量的测评体系.运用熵值法客观确定各指标的权重,实证评价了2010-2015年河北省11个地级市的城镇化质量的发展水平及动态变化趋势.结果表明:河北省11个地级市中除了秦皇岛和承德的城镇化质量略有提升外,其他各市均表现出不同程度下降,聚类分析的结果表明,导致各市城镇化质量差异的原因有所不同;城镇化水平、基本公共服务和基础设施这三个维度对城镇化质量呈现出不同程度的推动作用,而资源环境这一维度则表现出显著的阻碍作用.

Affine-inscribed and affine-circumscribed polygons and polytopes

Five theorems on polygons and polytopes inscribed in (or circumscribed about) a convex compact set in the plane or space are proved by topological methods. In particular, it is proved that for every interior point O of a convex compact set in ℝ³, there exists a two-dimensional section through O circumscribed about an affine image of a regular octagon. It is also proved that every compact convex set in ℝ³ (except the cases listed below) is circumscribed about an affine image of a cube-octahedron (the convex hull of the midpoints of the edges of a cube). Possible exceptions are provided by the bodies containing a parallelogram P and contained in a cylinder with directrix P. Bibliography: 29 titles.

Partitions and pairwise sums and products

A seven cell partition of N is constructed with the property that no infinite set has all of its pairwise sums and products in any one cell. A related Ramsey Theory question is shown to have different answers for two and three cell partitions.     

Linear birth and death models and associated Laguerre and Meixner polynomials

We study birth and death processes with linear rates λ_n = n + α + c + 1, μ_{n + 1} = n + c, n 0 and μ₀ is either zero or c. The spectral measures of both processes are found using generating functions and the integral transforms of Laplace and Stieltjes. The corresponding orthogonal polynomials generalize Laguerre polynomials and the choice μ₀ = c generates the associated Laguerre polynomials of Askey and Wimp. We investigate the orthogonal polynomials in both cases and give alternate proofs of some of the results of Askey and Wimp on the associated Laguerre polynomials. We also identify the spectra of the associated Charlier and Meixner polynomials as zeros of certain transcendental equations.     

Distributive and Multiplication Modules and Rings

We study rings in which every ideal is a finitely generated multiplication right ideal.     

Beliefs and beyond: affect and the teaching and learning of mathematics

The importance of beliefs for the teaching and learning of mathematics is widely recognized among mathematics educators. In this special issue, we explicitly address what we call “beliefs and beyond” to indicate the larger field surrounding beliefs in mathematics education. This is done to broaden the discussion to related concepts (which may not originate in mathematics education) and to consider the interconnectedness of concepts. In particular, we present some new developments at the conceptual level, address different approaches to investigate beliefs, highlight the role of student beliefs in problem-solving activities, and discuss teacher beliefs and their significance for professional development. One specific intention is to consider expertise from colleagues in the fields of educational research and psychology, side by side with perspectives provided by researchers from mathematics education.
