Mixing methods – assessment of potential benefits for natural resources planning

Multi-objective forest planning is a multi-methodological endeavor whose success largely depends on how well the combined use of different methods contributes to the goals of the planning. This review assessed the benefits of mixing methods in natural resources planning. A sample of 30 peer-reviewed research articles was analyzed using an evaluation framework, designed based on democracy and planning theories, and participatory planning literature, including four dimensions: transparency, flexibility, consensus building, and operability. According to analyses, mixing different types (i.e. qualitative and quantitative) of methods generally yields greater benefits than the combination of similar methods. The subsample of 12 planning cases that utilized simulation-optimization software (SOS) appeared operable and moderately transparent, whereas flexibility and consensus building were often lacking. In comparison to the wide scholarly discussion on multi-methodology and mixing methods, it was observed that successful mixing examples in natural resource planning are still scarce and there are weaknesses in bridging the methods together. There is an evident need to pursue and to better communicate the benefits of mixing. Some good mixing examples utilizing SOS provided evidence that forest planning processes would make an excellent venue for studying the benefits and caveats of using mixed methods.     

动物毛发的形态结构及其功能特性研究

对人发及其他14种动物毛发的扫描电镜(SEM)照片进行分析,根据它们形态结构特征将其分为指状结构、芽状结构、鳞状结构和波状结构4类,并就每种毛发结构的保温性、疏水性及其柔性进行了比较分析。分析结果表明,具有指状细观结构形态的毛发在保温性、疏水性及柔韧性方面具有明显优势,这一信息对研究开发新型功能材料具有借鉴作用     

外加盐对凉粉草胶溶液的耐盐性和分子链刚性度的影响

在有盐环境下贮藏和加工凉粉草胶必须了解其多糖分子对盐的敏感性，该文绘制了凉粉草胶多糖在不同离子强度NaCl、KCl、MgCl₂和CaCl₂溶液中的Huggins'图，分别计算其分子链在这4种离子溶液中的耐盐度S、链刚性度B等值，结果发现：凉粉草胶多糖在4种离子溶液中，其耐盐性由强到弱的顺序为:K⁺>Na⁺>Mg⁺⁺>Ca⁺⁺，其分子链的构象在4种离子溶液中由柔到刚的顺序为:K⁺>Na⁺>Mg⁺⁺>Ca⁺⁺，这说明凉粉草胶多糖适合在KCl溶液中贮藏和加工。与其他多糖分子链在NaCl溶液中的B值比较后发现，凉粉草胶多糖的分子链构象较海藻酸钠要刚，较黄原胶要柔，这说明凉粉草胶比黄原胶更适合在NaCl溶液中贮藏和加工。     

Surfers of the ocean waves: Change management,intersectoral migration and the economic development of small island states

This paper argues that there is a need to better acknowledge and problematise the manner in which individuals, households, organisations and governments in small island jurisdictions develop mechanisms that allow them to exploit the benefits, and/or minimise the losses, of episodic economic lurches. A ‘strategic flexibility’ approach is proposed to explain how actors practise intersectoral migration: cleverly shifting focus, interest and scope, not just out of necessity (reactively) but in ‘smelling’ promising opportunities (proactively). In a scenario where change is taken as a given, managing and coping with such change become the hallmarks of economic survival: just like surfers handling the ocean swell.

10个引进亚麻品种在云南的纤维产量和品质分析

报道2003年至2004年10个引进亚麻品种在云南省8个试验点的纤维产量和品质测定结果。3个国外品种的长麻率、总麻率、纤维产量明显高于国内品种;方差分析显示,不同地点间、不同品种间纤维产量差异显著。10个亚麻品种的平均分裂度变幅为344~407公支,平均断裂强力变幅为200~248 N,平均可挠度介于49.6~56.6 mm;同一品质指标在不同试点的变幅较大。方差分析结果表明,正麻品种间的纤维品质差异不显著,地点间的纤维品质差异显著。
