Sharing commerce is an e-commerce business model where service providers (who provide possession of goods) and customers (who acquire temporary ownership for a fee) are connected through commercial ...networking systems tailored by service enablers. Research on sharing commerce to date investigate key drivers of consumer engagement in sharing commerce platforms, but relatively little attention has been given to the role of trust, and trust formation. Drawing on the socio-technical theory, the purpose of this paper is to examine the effect of social and technical enablers on consumer trust and whether trust influences users' continued use and positive word-of-mouth (WOM) in the context of sharing commerce. Results of an empirical study (N = 211 active Airbnb millennial users) indicate that social referrals, information quality and transaction safety positively affect users’ trust, which in turn facilitate their continued intention to use the sharing commerce platform and share positive word-of-mouth testimonials and postings thus sharing positive consumption experiences with other consumers. Results also suggest that transaction security is approximately four times more effective at increasing trust than social referrals and 2.68 times more effective at enhancing trust than information quality.

Sharing economy platforms are growing at an unprecedented rate. Travel and tourism scholars have been focusing on customers’ sharing intention, yet the literature has largely overlooked what makes ...sharing service providers trust a sharing economy platform and decide to continue using it. Drawing on sociotechnical theory and the information systems success model, in conjunction with privacy concerns and economic value perspectives, this study develops an integrated model of antecedents and consequences of trust toward sharing economy platforms. Data from 606 Airbnb hosts were analyzed through structural equation modeling. Our research documents the importance of social antecedents (i.e., social value orientation and social utility), technical antecedents (i.e., system quality, service quality, and information quality), economic antecedents (i.e., monetary rewards) and privacy assurance antecedents (i.e., perceived effectiveness of privacy policy) in shaping hosts’ trust toward Airbnb, thereby enhancing their continuance intention with regard to using the platform.
Just as classic Marxist writers are included among the world's top-class artists, Chinese Marxism has gradually nurtured a new tradition of modern aesthetics. This tradition serves to enlighten the ...people, cultivate their appreciation of artistic masterpieces, and thus establish a complete set of artistic systems that has been inspiring people to constantly reflect on and improve themselves. Mao Zedong, Deng Xiaoping, and Xi Jinping, among other leaders, acquired a deep understanding of Marxist aesthetics and incorporated it in their policy making. At present, while reviewing the artistic achievements in the past hundred years, we must be fully aware of the deficiencies caused by reductionism and shortsightedness in literature and art. In order to overcome those problems, there are some useful lessons for artists and writers: getting in touch with people's concerns, depicting the lives they are familiar with, paying attention to national styles, deciphering the patterns of geographical aesthetics, and pursuing artistic individuality.

To deal with the ever-changing environment, sessile plants adapt diverse and plastic organ structures during postembryonic development. Among these, the apical hook forms shortly after seed ...germination of most dicots, and protects the delicate shoot meristem from mechanical damage during soil emergence. For decades, this structure has been taken as an excellent model for the investigation of the mechanisms underlying the differential growth of plant tissues. Here, we summarize recent advances in the investigation of the hormonal regulation of apical hook development, focusing on the convergence to auxin and a central regulator HOOKLESS1 (HLS1). We propose the revisitation of hook curvature kinematics at suborgan and single-cell resolution, and further pursuance of the mechanistics of apical hook development through combinatorial approaches of automated imaging and multidimensional modeling.
Peptide-mediated cell-to-cell signaling has crucial roles in coordination and definition of cellular functions in plants. Peptide-receptor matching is important for understanding the mechanisms ...underlying peptide-mediated sig- naling. Here we report the structure-guided identification of root meristem growth factor （RGF） receptors important for plant development. An assay based on a signature ligand recognition motif （Arg-x-Arg） conserved in a subfamily of leucine-rich repeat receptor kinases CLRR-RKs） identified the functionally uncharacterized LRR-RK At4926540 as a receptor of RGF1 （RGFR1）. We further solved the crystal structure of RGF1 in complex with the LRR domain of RGFR1 at a resolution of 2.6 A, which reveals that the Arg-x-Gly-Gly （RxGG） motif is responsible for specific rec- ognition of the sulfate group of RGF1 by RGFR1. Based on the RxGG motif, we identified additional four RGFRs. Participation of the five RGFRs in RGF-induced signaling is supported by biochemical and genetic data. We also of- fer evidence showing that SERKs function as co-receptors for RGFs. Taken together, our study identifies RGF receptors and co-receptors that can link RGF signals with their downstream components and provides a proof of principle for structure-based matching of LRR-RKs with their peptide ligands.

The use of the internet and social media have changed consumer behavior and the ways in which companies conduct their business. Social and digital marketing offers significant opportunities to organizations through lower costs, improved brand awareness and increased sales. However, significant challenges exist from negative electronic word-of-mouth as well as intrusive and irritating online brand presence. This article brings together the collective insight from several leading experts on issues relating to digital and social media marketing. The experts’ perspectives offer a detailed narrative on key aspects of this important topic as well as perspectives on more specific issues including artificial intelligence, augmented reality marketing, digital content management, mobile marketing and advertising, B2B marketing, electronic word of mouth and ethical issues therein. This research offers a significant and timely contribution to both researchers and practitioners in the form of challenges and opportunities where we highlight the limitations within the current research, outline the research gaps and develop the questions and propositions that can help advance knowledge within the domain of digital and social marketing.
Ethylene is a gaseous phytohormone that plays vital roles in plant growth and development. Previous studies uncovered EIN2 as an essential signal transducer linking ethylene perception on ER to ...transcriptional regulation in the nucleus through a “cleave and shuttle” model. In this study, we report another mechanism of EIN2-mediated ethylene signaling, whereby EIN2 imposes the translational repression of EBF1 and EBF2 mRNA. We find that the EBF1/2 3′ UTRs mediate EIN2-directed translational repression and identify multiple poly-uridylates (PolyU) motifs as functional cis elements of 3′ UTRs. Furthermore, we demonstrate that ethylene induces EIN2 to associate with 3′ UTRs and target EBF1/2 mRNA to cytoplasmic processing-body (P-body) through interacting with multiple P-body factors, including EIN5 and PABs. Our study illustrates translational regulation as a key step in ethylene signaling and presents mRNA 3′ UTR functioning as a “signal transducer” to sense and relay cellular signaling in plants.

Inspired by natural biomolecular machines, synthetic molecular-level machines have been proven to perform well-defined mechanical tasks and measurable work. To mimic the function of channel proteins, ...we herein report the development of a synthetic molecular shuttle, 2rotaxane 3, as a unimolecular vehicle that can be inserted into lipid bilayers to perform passive ion transport through its stochastic shuttling motion. The 2rotaxane molecular shuttle is composed of an amphiphilic molecular thread with three binding stations, which is interlocked in a macrocycle wheel component that tethers a K+ carrier. The structural characteristics enable the rotaxane to transport ions across the lipid bilayers, similar to a cable car, transporting K+ with an EC50 value of 1.0 μM (3.0 mol % relative to lipid). We expect that this simple molecular machine will provide new opportunities for developing more effective and selective ion transporters.
SUMMARY
Gas hydrates that occur on many continental margins have received global attention. In reflection seismic imaging, the bottom-simulating reflector (BSR) is a common indicator of gas hydrates. ...However, it is difficult to identify gas hydrates and quantify their amounts through the BSR alone. For gas-hydrate characterization, it is therefore useful to measure seismic stratigraphic and attenuation attributes. Short-scale patterns of layering that contain information about the amount and mechanism of gas hydrates can be identified through stratigraphic and attenuation attributes. We measure the complete time-variant spectra by using sparse strongest peaks, and the spectral differences at different times through attenuation parameters Q–1 and γ. The traditional Q–1 is associated with the attenuation of the frequency-dependent part of wavefield, and the γ characterizes the frequency-independent attenuation. The measurement approach is straightforward and requires no sophisticated inverse algorithm and is applied to surface seismic data acquired over the Hikurangi and Gondwana margins, eastern New Zealand. High-quality spectral and attenuation images are obtained. Spectral attributes correlate with BSRs and large positive Q–1 and negative γ-values are below and above the BSRs, which are interpreted as being related to free-gas and gas-hydrate accumulations. These results will aid the quantification of gas hydrates and the assessment of their roles as an energy resource, as a potential geological hazard, and in climate change and ocean warming.
