绿色发展作为我国"十三五"规划乃至以后长时间的发展基本理念,体现了我国调整产业结构、转变发展模式、实现绿色低碳循环发展的必然选择.企业为使碳排放管理绩效能真正改善物流环境,现阶段很多物流企业以系统动力学为指导思想,通过分析在物流企业中影响碳排放的因素,设计了适用于物流业的指标体系,对物流业的碳排放进行绩效评价.本文通过研究绿色发展视阈下的物流业碳绩效评价,希望能够为物流企业碳绩效管理的提供改善的方向.物流服务本身是以低成本方式,经过运输等环节,将货品送达客户.但低碳时代的到来,使得企业必须把低碳服务摆在首位.节能减碳就意味着服务水平的方式也要发生变化,企业面临了双重压力,但低碳发展俨然已成为整个物流行业的发展导向.多数物流企业没有全面认识节能减碳,在运输过程中只关注到了自身,然而物流企业所涉及运输路线较多,完全可以协同其他路线共同减碳.在企业设计相应的评价指标体系时,应考虑到低碳管理多方面的影响因素,设计出一套综合性强且可持续操作的评价指标体系,降低低碳管理的复杂性,全面推动物流企业及各相关企业的发展.

废弃物产出所造成的环境损害是传统绩效评价所无法反映的,其评价方法难以适应当前可持续发展的要求.通过回顾国内外相关研究成果,分别对碳绩效的发展历程、评价方法以及评价体系构建的研究动态做了梳理.此外,通过分析含碳原料在生产工序中的流动,将资源价值流方法应用于企业碳绩效评价中,试图以此促进我国企业碳绩效评价的纵深发展.

绿色发展意味着对高污染、高能耗发展方式的否定,是一种新型发展模式.文章对碳绩效的发展历程做了梳理,从投入和产出两方面,结合国内外环境绩效评价标准,设计出碳绩效指标.最后采用DEA基础模型对37种类型企业在2014-2016年的碳绩效进行测算,结果发现,该37种类型企业存在燃料消耗总量过高、人员配备结构不合理等问题.通过构建碳绩效评价指标体系,并将该体系进行初步应用,以期对企业实现绿色发展提供理论参考和实践指导.

企业生态绩效审计旨在激励企业开展生态管理行为和挖掘企业资源利用效率潜力.选取在2015-2016两年间我国上市公司社会责任报告或可持续发展报告中所披露的环境数据实施生态绩效审计后,验证了我国金融市场对生态绩效审计信息的反应.实证结果表明,一方面,企业每股收益可积极反映生态绩效审计信息;另一方面,此类信息对企业每股收益的反映程度并不一致.论文通过构建生态绩效指标体系,实施生态绩效审计是企业实施低碳管理、形成绿色生产方式的一种前瞻性手段,其有用性在理论和实践上都已被广泛接受.

A cDNA library and an EST library of Camellia oleifera were constructed.A 14-3-3 protein gene was cloned from Camellia oleifera.This gene is 1 156 bp in length,including 57 bp of 5'untranslated region and 301 bp of 3'untranslated region.It has an open reading flame of 777 bp,encoding a protein of 259 amino acid residues with protein molecular weight of 29.466 ku and isoelectric point of 4.78.No signal peptide sequence was found,which shows it's a non-secreted protein.This gene is named Co-14-3-3a.The speculated secondary structure of Co-14-3-3a consists of nine helices and an extended-beta located between αC and αD.

以构建的油茶cDNA文库为基础,采用交错延伸PCR技术,分离克隆到一个水通道蛋白基因的编码序列(coding sequence,CDS),它编码一个287aa的跨膜蛋白(GenBank蛋白质id:ACF39901).该蛋白可能由2条基因(GenBank登录号:EU850810、EU850811)编码,这2个基因具有相同的CDS和3'-UTR,但5'-UTR不同,其中之一多了2个小的插入片段.经对该蛋白的同源性比对和特征性基序分析,推测这个水通道蛋白属于质膜内在蛋白成员,定名为CoPIP1-1.通过同源建模,论证CoPIP1-1的水通道活性与通道口的(去)覆盖有关.N端与D环、B环的静电势作用导致了对通道口的(去)覆盖,并受磷酸化,质子化门控机制调控,质子化抑制通道活性,磷酸化则解除抑制.从同源建模的结果和细胞内的氧化状态推测该蛋白为组成型的低活性,这可能是油茶种子近成熟期脱水的成因之一.

Based on a constructed cDNA library of Camellia oleifera,a full-length cDNA(GenBank accession number: EU856537) encoding a dehydrin-like protein(id:ACF72673) composed of 208 amino acids,was cloned from the seeds by 5′-RACE technique.This putative protein should belong to the SK2-type dehydrin by homology analysis,designated as CoDHN2.In its polypeptide the region between the domains of the two similar K-segments is rich in threonine,which is different from the general characteristics of other dehydrins.CoDHN2 dehydrin shared a highly conserved motif of EDDGQGGRRKK,which might contribute to dehydrin's phosphorylation and hence subcellular localization,as another dehydrin do in the seeds of C.oleifera.Prediction of secondary structure via various methods showed that CoDHN2 was intrinsically unstructured,but one of its K-segments can be changed into a α-amphipathic helix.Due to its relatively rich histidine content and good solvent accessibility,It was proposed that CoDHN2 may bind heavy metal ions,and thus eliminate ROS sources caused by these ions and scavenge ROS,or may also serve as buffer for some physiological process under the condition of water deficient.Considering the progress of study on dehydrin,it was speculated that the CoDHN2 was very possible to bind the developing lipid body and protect them against the ROS during rapid biosynthesis of lipid in the C.oleifera seeds,which give a new clue to study the development of lipid body in the seeds of C.oleifera.
