Exploring the concept of coopetition: A typology for the strategic moves of the Finnish forest industry

The Finnish forest industry is sustainable, well-established, internationally oriented and successful. For companies in such a basic industry, an industry that features mainly bulk products and relatively small domestic markets, sustainability in business may hinge on long-term strategic choices. It is proposed in this paper that it is not only strong domestic competition, but also—and especially—coopetition traditions (simultaneous cooperation and coopetition) that are the crucial factors contributing to the success of the industry. This article contributes to the literature by providing industry-level tools, namely a coopetition framework and combined coopetition typology. The findings indicate that coopetition traditions have been present throughout the activities of the Finnish forest industry, enabling sustainability of the industry to a significant extent. Managerial and theoretical implications are also discussed.     

从“森林效应”看民办高校教师绩效考核体系构建的必要性

我国民办高等教育起步时间不长,与公办院校相比,仍旧差距明显,在诸多差距中,师资水平差距首当其冲。本文以"森林效应"为启示,着重论述了教师绩效考核体系的构建对民办高校师资队伍建设的意义和作用。     

The interface of the energy and forest sectors—Potential players in the bioenergy business

The upcoming bioenergy business area opens up promising opportunities for the traditional energy and forest sectors. This has motivated us to study existing and potential bioenergy actors that could take up this unique opportunity and develop new business around the “green gold” of the forest. Light is shed on the interface between the energy and forest sectors through a comparison of the most focal bioenergy actors with traditional forest and energy companies. The analytical methods used include both parametric and nonparametric analysis of variance, and cluster analysis. The result is a better understanding of the players that have the potential to capitalize on the emerging business.     

信息技术在林火探测中的应用

本文在介绍信息技术的基础上。搜集了大量的林火探测方法,分析了人为探测的优缺点以及利用信息技术进行林火探测的必要性。信息技术在林火探测中的应用主要包括4个方面：红外探测、感烟探测、卫星遥感探测和视频图像探测。本文分析了各种信息技术的探火原理以及优缺点,并指出在不同的环境背景下应该选择不同的信息技术进行林火探测．必要的时候可以使用复合型的林火探测方式。一般来说,红外探测和感烟探测比较适合近距离的林火探测．因为红外和烟雾容易受周围环境的影响而有不同程度的削减;对于大面积的森林监测应该采用卫星遥感技术,但由于其覆盖周期长,应用于林火探测上尚有一定距离,在林火灾后评估方面有很好的应用效果;视频图像林火探测是一门新兴的信息技术,虽然有其他方法所不可比拟的优越性,但在应用过程中,其缺点也应受到人们的重视。随着信息技术日新月异的发展,林火探测技术将会越来越科学、准确。

A landscape approach for assessing the biodiversity value of indigenous forest remnants: Case study of the Manawatu/Wanganui region of New Zealand

To halt the decline of biodiversity in New Zealand, the government has formulated a strategy of maintaining and restoring a full range of remaining natural habitats to a healthy functioning state. Many indigenous forest remnants exist on private land, and these could be utilised to increase biodiversity. Resources for conservation of forest remnants are limited, so they must be used wisely to deliver the greatest possible biodiversity gain. This paper presents a rapid method for valuing the biodiversity of a region's indigenous forest remnants to help prioritise conservation resources. The region is divided into environmentally distinct areas called land environments. A detailed land-cover map is derived from satellite imagery and used to estimate the proportion of natural habitats remaining in each land environment; from this the biodiversity value of any forest remnant may be calculated. The method is rapid and does not require detailed biodiversity information. When combined with conservation costs, it may be used to create a priority list of forest remnants for conservation. The Manawatu/Wanganui region of New Zealand is used as a case study to demonstrate the method.     

基于变异系数和锡尔指数的中国区域经济差异分析

本文从中国三大经济区的划分入手,选取人均GDP作为测评指标,用变异系数和锡尔指数对1978~2008年的区域差异水平进行定量测度。结果表明:①全国范围内区域经济绝对差异不断拉大,相对差异有所缩小;②东部与中西部差异十分明显,而中西部之间差异不甚明显;③东部地区内部差异呈不断缩小趋势,中部呈波动中下降趋势,西部处于波动中,但总体变化不大。对造成该现象的原因作简要分析,认为主要原因有区域环境、要素投入、制度性因素。
