Jie Wu,Ze-Fu Wu 글로벌지식마케팅경영학회 2014 Global Marketing Conference Vol.2014 No.10

In an increasingly dynamic business environment, innovation output occupies a central position among all organizational outputs, not only because it is a primary way in which firms compete and grow, but also because it profoundly influences social and economic evolution (Eisenhardt & Tabrizi, 1995; Sorensen & Stuart, 2000). Understanding the factors that determine an organization’s ability to produce new ideas and continually innovate thus is a fundamental issue in strategic management and marketing fields. Among all sort of determinants, collaboration with buyers to create value through innovation has attracted particular attention from scholars (von Hippel, 1988; Thomke & von Hippel, 2002; Sawhney, Verona, & Prandelli, 2005). This study examined the role of Internet-based collaboration in the buyer-supplier relationship in promoting product innovation of supplying firms. Drawing on the juxtaposition of the governance literature and social exchange theory, we proposed that Internet-based collaboration positively affects product innovation performance of supplying firms, but too much dependence on it impedes product innovation. That is, Internet-based collaboration has an inverted U-shaped relationship with product innovation performance of supplying firms. It further posited that in-person interaction between buying and supplying firms strengthens the positive effect of Internet-based collaboration on product innovation, such that when the degree of in-person interaction is high, Internet-based collaboration is associated with better innovation performance. These propositions were tested using data from a large survey conducted by a survey data on buyer-supplier relationships in China. The results show that Internet-based collaboration has a stronger positive relationship with innovation performance and this positive effect declines after the degree of Internet-based collaboration goes beyond a threshold. Moreover, the first-order effect of Internet-based collaboration is stronger when the degree of in-person interaction is high than when it is low. The optimal level of Internet-based collaboration in low degree of in-person interaction is moderate, whereas when in-person interaction is more frequently used in connecting with buying firms the optimal level rises. These results provide strong supports for the predictions of hypotheses.

Sediment microbial fuel cells (SMFCs) are attractive devices to in situ power environmental monitoring sensors and bioremediate contaminated soils/sediments. Burial depth of the anode was verified to affect the performance of SMFCs. The present research evaluated the differences in microbial community structure of anodic biofilms located at different depth. It was demonstrated that both microbial diversity and community structure of anodic biofilms were influenced by the depth of anode location. Microbial diversity decreased with increased anodic depth. The number of the operational taxonomic units (OTUs) was determined as 1438 at the anode depth of 5 cm, which reduced to 1275 and 1005 at 10 cm and 15 cm, respectively. Cluster analysis revealed that microbial communities of 5 cm and 10 cm were clustered together, separated from the original sediment and 15 cm. Proteobacteria was the predominant phylum in all samples, followed by Bacteroidetes and Firmicutes. Beta- and Gamma-proteobacteria were the most abundant classes. A total of 23 OTUs showed high identity to 16S rRNA gene of exoelectrogens such as Geobacter and Pseudomonas. The present results provided insights into the effects of anode depth on the performance of SMFC from the perspectives of microbial community structure.

Cap ‘n’ collar C (CncC), a transcription factor, plays a vital role in the development of insect resistance by regulating the expression of multiple detoxifying genes. Clarifying the molecular characteristics of CncC and its pathway regulating insecticide resistance will aid the development of integrated pest control strategies. Here we cloned and identified the molecular feature of CncC genes from the brown planthopper (BPH), Nilaparvata lugens (Stål), (Hemiptera Delphacidae). The full-length open reading frame of NlCncC was 3015 nucleotides with 1005 amino acids. The deduced amino acid sequence has a high similarity with other insect homologs and contains the characteristic Cnc/bZip domain architecture. Functional studies showed that silencing NlCncC by RNA interference (RNAi) could downregulate the transcript expression of NlCYP6ER1, NlCYP6CW1, and NlCYP6AY1, which increase the susceptibility to imidacloprid in N. lugens. The identification of molecular characteristics of NlCncC and func tional studies in this paper will contribute to designing effective control strategies for N. lugens.

Based on ions exchange between [DMDSA]+[Cl]- (Dimethyl distearyl ammonium chloride) and N,Ndialkyl-succinamide acid (SCA), three novel bifunctional [DMDSA]+[SCA]- ionic liquids (ILs) were firstlysynthesized for extraction of thorium (IV) by self-assembly strategy. The simultaneous extraction andsolidification of Th(IV) were unexpectedly realized in one-step operation using the present ILs in HNO3solution, and more than 99% thorium (IV) was enriched and immediately aggregated into selfassemblysolid at the biphasic interface. The self-assembly solid was further identified by FT-IR, SEM withelement mapping EDS and XPS analysis, and revealing that the self-assembly extraction (SAE) was triggeredby the amphiphilic [DMDSA]+ cations. A three-step extraction mechanism dominated by [SCATh(NO3)4]- was proposed based on the slope analysis method and HRMS analysis. The self-assembly extractionof Th(IV) exhibited the extremely excellent selectivity in the presence of U(VI) and typical lanthanideelements including La(III), Eu(III) and Lu(III), and the separation factors reached 2516 for Th/U, 1885 forTh/La, 1512 for Th/Eu and 558 for Th/Lu, respectively. The proposed SAE strategy was proved to be anefficient method for one-step separation and solidification of thorium ions from U(VI) and/or lanthanides.

Swine influenza viruses (SwIVs) cause considerable morbidity and mortality in domestic pigs, resulting in a significant economic burden. Moreover, pigs have been considered to be a possible mixing vessel in which novel strains loom. Here, we developed and evaluated a novel M2e-multiple antigenic peptide (M2e-MAP) as a supplemental antigen for inactivated H3N2 vaccine to provide cross-protection against two main subtypes of SwIVs, H1N1 and H3N2. The novel tetra-branched MAP was constructed by fusing four copies of M2e to one copy of foreign T helper cell epitopes. A high-yield reassortant H3N2 virus was generated by plasmid based reverse genetics. The efficacy of the novel H3N2 inactivated vaccines with or without M2e-MAP supplementation was evaluated in a mouse model. M2e-MAP conjugated vaccine induced strong antibody responses in mice. Complete protection against the heterologous swine H1N1 virus was observed in mice vaccinated with M2e-MAP combined vaccine. Moreover, this novel peptide confers protection against lethal challenge of A/Puerto Rico/8/34 (H1N1). Taken together, our results suggest the combined immunization of reassortant inactivated H3N2 vaccine and the novel M2e-MAP provided cross-protection against swine and human viruses and may serve as a promising approach for influenza vaccine development.
