eCRM ties customer relationship management with e-business. Very often, eCRM is interfaced with other information systems to form a seamless integration and interchange of information both inside and outside an organization--a work flow management system. This integration of business partners, suppliers, and customers is essential in this global competitive market environment. An effective infrastructure and hence an appropriate framework are required to provide the information exchange and data analysis between eCRM and work flow management. This paper proposes a functional framework of eCRM based on customer value to realize the win-win strategy for both the companies and their customers. Moreover, a workflow management system also forms an integral part of this total solution to facilitate the implementation of a supply chain or extended enterprise.

BACKGROUND:Micro-RNAs(miRNAs) are small,non-coding RNA species considered to fine-tune basic cellular functions by modulating target gene translation and/or mRNA stability.A common G/C polymorphism(rs2910164) in the precursor(pre-) miR-146a gene engaged in NF-κB signaling and apoptosis pathways has been reported to modulate the genetic risk of hepatocellular carcinoma by increased G-allelic production of mature *** investigated rs2910164 in a large Europeanbased cholangiocarcinoma(CCA) ***:We recruited 182 CCA patients and 350 controls in three academic medical *** for rs2910164 was performed by PCR-based assays with 5’-nuclease and fluorescence *** frequencies were tested for consistency with the hardy-Weinberg equilibrium using an exact test;allelic and genotypic differences between the patients and controls were assessed by the Chi-square test and Armitage’s trend *** subgroup analyses included gender,tumor localization(extra-versus intrahepatic CCA) and early-onset ***:Genotype distributions were consistent with the hardy-Weinberg *** significant differences in either allele or genotype distributions were detected between the CCA and control groups or the respective subgroups ***,there was a trend for a protective effect of the heterozygous single-nucleotide polymorphism state GC,as indicated by an underrepresentation in the CCA group in general(29% vs 35%;P=0.18) and,in particular,for extrahepatic tumor sites(26% vs 35%;OR=0.67;95% CI,0.43-1.02;P=0.065).CONCLUSIONS:Our data do not support a prominent contribution of the pre-miR-146a sequence variant in the genetic predisposition to ***,current studies functionally characterizing rs2910164 have proposed that distinct repertoires of target genes are addressed by genotype-specific mature miR146a *** the detected trend towards a potentially protective role of GC heterozygosity,a subtle modulation of g

该文运用CLUE-S模型模拟研究了贵州中部猫跳河流域在不同情景模式下未来十年内土地覆被的空间变化情况。根据研究区土地覆被结构的现状以及影响土地覆被变化的宏观因素,作者设计了生态安全目标、粮食安全目标、经济发展目标以及综合发展目标等4种可能出现的情景。结果表明,在不同土地利用情景下,猫跳河流域未来十年的土地覆被格局及其效应存在明显的差别。生态安全目标情景能在较大程度上改善流域的生态环境,但会对流域的粮食安全构成较大的威胁。粮食安全目标情景能够保障流域的粮食安全,但会导致区域生态环境质量下降。经济发展目标模式可充分保障经济建设用地的需求,但会威胁到流域的粮食安全。综合发展目标情景比较全面地考虑到了流域经济发展、生态保护以及粮食安全等需要,是研究区未来较为可取的土地利用模式。
