Ecological restoration of a fragmented urban shrine forest in southeastern Hyogo Prefecture,Japan: Initial effects of the removal of invasive <Emphasis Type="Italic">Trachycarpus fortunei</Emphasis>

We investigated the species composition of a fragmented forest in Nishinomiya Shrine, southeastern Hyogo Prefecture, Japan. Two escaped ornamental species, Trachycarpus fortunei and Ligustrum lucidum, and bird-dispersed deciduous trees were invading the evergreen broadleaf forest. Invasive and bird-dispersed deciduous species were most abundant along the outer edge of the forest. In 2005, restoration measures were taken to remove all individuals of T. fortunei from the forest. We estimated that, biomass density and leaf area index (LAI, leaf area per unit ground area) of T. fortunei were 0.23 kg m⁻² and 0.77, respectively, which accounted for 8.9% and 27.9% of the biomass density and LAI, respectively, of the entire forest. After removal, canopy openness increased in the understory. However, the understory lacked seedlings and saplings of native species, indicating that active re-vegetation may be needed to accelerate reestablishment of native species in areas that were heavily invaded by T. fortunei. This study represents one of the first examples of active vegetation management in shrine/temple forests in Japan.     

The impact of offshoring on firm competitiveness

Offshoring strategies, in spite of their continuous growth, have not always delivered the expected results: cost savings are often much lower than expected, customers may be considerably upset, and relevant competences can be lost for the future. This article looks at the impacts of offshoring on firm competitiveness, in the short and in the long term. The analysis is based on two managerial theories (the contingency theory and the resource-based view of the firm) taking as reference two relevant offshoring business cases: the fashion industry and the information system management. It appears that offshoring, besides its short-term impacts on cost reduction and its long-term risks for core activities, is a comprehensive transformational process that only few companies can afford not to learn from.     

Multivariate boundary kernels and a continuous least squares principle

Whereas there are many references on univariate boundary kernels, the construction of boundary kernels for multivariate density and curve estimation has not been investigated in detail. The use of multivariate boundary kernels ensures global consistency of multivariate kernel estimates as measured by the integrated mean-squared error or sup-norm deviation for functions with compact support. We develop a class of boundary kernels which work for any support, regardless of the complexity of its boundary. Our construction yields a boundary kernel for each point in the boundary region where the function is to be estimated. These boundary kernels provide a natural continuation of non-negative kernels used in the interior onto the boundary. They are obtained as solutions of the same kernel-generating variational problem which also produces the kernel function used in the interior as its solution. We discuss the numerical implementation of the proposed boundary kernels and their relationship to locally weighted least squares. Along the way we establish a continuous least squares principle and a continuous analogue of the Gauss–Markov theorem.

"文学史上的失踪者":穆木天 --中国现代文学中的左翼文学论(一)

穆木天思想和创作在中国现代文学中是一个十分复杂的现象,其核心体现了与"边缘文化"相联系的左翼文学的精神特征,与30年代左翼文学的灵魂--鲁迅有着一致的精神趋向.以鲁迅为代表的左翼文学体现了中国现代文学的"先锋性",在这个问题上,穆木天的文艺思想既有重要的价值,又存在着局限性,这种局限是与他的"日本体验"密切相关的.     

虚拟衍生企业的竞争力研究

论阳明心学对儒学理论形态的转型及其启示

宋明时期儒学理论形态从程朱理学向阳明心学的转型,道德教化的路径从“外烁型”向“内化型”的转型,对于我们今天如何提升社会主义核心价值观的社会主导力有借鉴意义.阳明心学对程朱理学的理论革新中形成的“心理合一”、“物我合一”、“情理合一”、“知行合一”的道德教化思想启示我们,从当代中国社会转型的实际出发,要使核心价值观保持应有主导力,在思想内化的路径上也要实现多方面的转型:要从立足抽象的宏观的超群的对象向立足具体的当下的个体自主的对象转型；要从突出为国为民的理想境界向为国为民与为家为已并重的现世境界转型；要从着眼为了抽象的未来的整体的利益向具体的现实的日常的利益转型；要从“崇尚先进”的圣贤路径向“凡圣平等”的世俗路径转型.
