Abstract

Background The influence of foliar nitrogen fertilizer during veraison (FNFV) on anthocyanin accumulation and chromatic characteristics of 'Cabernet Sauvignon' grapes over two seasons was investigated. Results Urea and phenylalanine fertilizers (TU and TP, respectively) and a control were sprayed three times at veraison. In 2018, TU displayed a significant enhancement in total individual anthocyanin content and a* and Cab * profiles. In 2019, FNAV significantly improved the content of total non-acylated, acylated anthocyanin and total individual anthocyanin, and the profiles of L*, a* and Cab *, except a* in TU. The whole process from phenylalanine variation to anthocyanin accumulation in grape skins was analyzed. On the whole, after the first FNFV to harvest, the increase in phenylalanine metabolism, abscisic acid content, effects of PAL (Phenylalanine ammonia lyase), UFGT (UDP glucose-flavonoid 3-O-glucosyltransferase) and transcript concentrations of VvPAL and VvUFGT involved in anthocyanin biosynthesis were also strong evidence explaining the increased anthocyanin and chromatic profiles in 2019. Conclusion Overall, FNFV for nitrogen-deficient grapevines could significantly improve grape color, especially in the 2019 veraison with a proper climate. © 2021 Society of Chemical Industry.

Abstract

Contemporary IT project teams demand individual members to generate and implement novel ideas in response to the dynamic changes in IT and business requirements. Firms rely on multi-disciplinary, geographically-distributed IT project teams to gather necessary talents, regardless of their locations, for developing novel IT artifacts. In this team context, individuals are expected to leverage dissimilar others’ expertise for creating ideas during idea generation (IG) and then implement their ideas during idea implementation (II), known as the IGII process. Although much has been done to explain individual creativity, the extant literature offers little theoretical understanding on how to address the double-edged effects of dispersions in both functional expertise (ExpDisp) and geographical locations (GeoDiss)—the two defining characteristics of multi-disciplinary, cross-locational IT project teams—on individual creativity and subsequent performance. Drawing on the IGII framework, we propose transactive memory systems (TMSs) as a plausible team-level solution to tackle the challenge. With a multi-wave multi-level dataset from 141 members and their supervisors from 35 IT project teams, we found that team-level TMS and GeoDiss interactively moderate individual-level IGII processes in multi-disciplinary geographically -distributed IT project teams during both II and IG, but in qualitatively different ways.

Beamish (2) Abstract: abstract The impact of knowledge transfer on foreign subsidiary performance has been a major focus of research on knowledge management in multinational enterprises (MNEs). By integrating the knowledge-based view and the expatriation literature, this study examines the relationship between a multinational firm's knowledge (i.e. marketing and technological knowledge), its use of expatriates, and the performance of its foreign subsidiaries. We conceptualize that expatriates play a contingent role in facilitating the transfer and redeployment of a parent firm's knowledge to its subsidiary, depending on the location specificity of the organizational knowledge being transferred and the time of transfer. Our analysis of 1660 foreign subsidiaries of Japanese firms over a 15-year period indicates that the number of expatriates relative to the total number of subsidiary employees (1) strengthened the effect of a parent firm's technological knowledge (with low location specificity) on subsidiary performance in the short term, but (2) weakened the impact of the parent firm's marketing knowledge (with high location specificity) on subsidiary performance in the long term. We also found that the expatriates' influence on knowledge transfer eventually disappeared. The implications for knowledge transfer research and the expatriate management literature are discussed.

Abstract

The wine industry is focused on the producing wine mostly from European grapevine varieties (Vitis vinifera L.). China has experienced a significant growth of the vineyard surface, based on the cultivation of these grapevine varieties. Currently, China has become one of the countries with the largest surface of planted vineyards in the world. In the last years, there has been a trend to oenologically and viticulturally revalorize certain autochthonous grapevine species. China holds a great diversity of Vitis species, which are being the focus of study. This could be an important alternative for the diversification of wine production, providing new products with a strong identity. Additionally, the varietal homogenization has increased the vineyard genetic vulnerability in relation to the emergence of grapevine diseases and their resistance to chemical fungicides. In this way, non-Vitis vinifera species are characterized by having a high resistance to a wide range of biotic and abiotic factors, which can bring an opportunity to breed new varieties. However, there is little available information about the oenological potential of these species, which makes it a current interesting topic. Therefore, this review aims to summarize the oenological potential of non-Vitis vinifera species found in China, discussing their potential effects on human health and thus, to propose some Chinese wild grapes for their use in breeding programs., This study was supported by the National Nature Science Foundation Project of China (31901971)

177. Knowledge coordination via digital artefacts in highly dispersed teams.

Abstract

Virtual teams face the unique challenge of coordinating their knowledge work across time, space, and people. Information technologies, and digital artefacts in particular, are essential to supporting coordination in highly dispersed teams, yet the extant literature is limited in explaining how such teams produce and reproduce digital artefacts for coordination. This paper describes a qualitative case study that examined the day‐to‐day practices of two highly dispersed virtual teams, with the initial conceptual lens informed by Carlile's (2004) knowledge management framework. Our observations suggest that knowledge coordination in these highly dispersed virtual teams involves the continuous production and reproduction of digital artefacts (which we refer to as technology practices) through three paired modes: 'presenting‐accessing' (related to knowledge transfer); 'representing‐adding' (related to knowledge translation); and 'moulding‐challenging' (related to knowledge transformation). We also observed an unexpected fourth pair of technology practices, 'withholding‐ignoring,' that had the effect of delaying certain knowledge coordination processes. Our findings contribute to both the knowledge coordination literature and the practical use of digital artefacts in virtual teams. Future research directions are discussed. [ABSTRACT FROM AUTHOR]

Abstract

Hep G2 cells were used to study the synthesis and secretion of phospholipid transfer protein (PLTP). Upon incubation of the cells at confluence with serum-free Duibecco's modified Eagle's medium (DMEM), phosphatidylcholine (PC) transfer activity was found to accumulate in the culture media. The PC transfer activity in the media was effectively inhibited by rabbit anti-human PLTP immunoglobulin (Ig)G, thus indicating that the PC transfer activity was due to secreted PLTP. The molecular weight of Hep G2 PLTP was approximately 78 kDa by Western blot analysis, in agreement with the molecular weight obtained for purified human plasma PLTP. The PLTP secreted by Hep G2 also possessed an HDL conversion activity similar to that of human plasma PLTP. The addition of butyrate to the cell culture media resulted in a marked increase in the secretion of PLTP. After 24 h incubation with 4 mmol/L sodium butyrate, a more than twofold increase (P < 0.01) of PC transfer activity in the cell-conditioned media was obtained. The dose-dependent increase in the PC transfer activity in the media upon butyrate treatment was well correlated (r = 0.80, P < 0.01) with that of PLTP mass as determined by immuno-slot blot analysis of cell-conditioned media. The increased secretion of PLTP by Hep G2 treated with sodium butyrate was accompanied by a greater increase in the level of PLTP mRNA in the cells as determined by ribonuclease protection assay. In the presence of 4 mmol/L sodium butyrate, a fourfold increase (P < 0.01) in mRNA level was obtained at 24 h. No stabilizing effect of butyrate on PLTP mRNA was apparent upon treatment of the cultured cells with the RNA synthesis inhibitor, actinomycin D. Thus, the up-regulatory effect of butyrate on PLTP gene expression seemed to have occurred at the transcriptional level.
