To solve the problem of low accuracy of traditional travel route recommendation algorithm, a travel route recommendation algorithm based on interest theme and distance matching is proposed in this paper. Firstly, the real historical travel footprints of users are obtained through analysis. Then, the user’s preferences of interest theme and distance matching are proposed based on the user’s stay in each scenic spot. Finally, the optimal travel route calculation method is designed under the given travel time limit, starting point, and end point. Experiments on the real data set of the Flickr social network showed that the proposed algorithm has a higher accuracy rate and recall rate, compared with the traditional algorithm that only considers the interest theme and the algorithm which only considers the distance matching.

Purpose As celebrity endorsements have extended from traditional media to social media, the role of celebrities has been amplified and celebrities have been able to establish unprecedentedly close relationships through interacting with consumers. This study, grounded in the theory of parasocial interactions and celebrity endorsement, aims to propose a framework of antecedents and outcomes of parasocial interactions with celebrities on social media. Design/methodology/approach Using an experimental survey-based approach, this study collected 270 usable responses, and data were analyzed using partial least square structural equation modeling. Findings The study found that parasocial interactions fully mediate the relationship between social media interaction and celebrity attachment, celebrity attachment influences purchase intention directly and indirectly through both cognitive (brand credibility) and affective (brand attractiveness) elements, the need to belong moderates the relationship between social media interaction and parasocial interactions and the need to belong moderates the relationship between celebrity attachment and brand attractiveness. An exploratory analysis uncovers whether different types of social platforms may be more conducive to establishing parasocial interactions. Originality/value This study explores the mechanisms by which celebrity interactions on social media can impact the brands they endorse and the role that parasocial interactions and the need to belong play in these interactions and outcomes.

Terahertz (THz) waves show great potential in nondestructive testing, biodetection and cancer imaging. Despite recent progress in THz wave near-field probes/apertures enabling raster scanning of an object’s surface, an efficient, nonscanning, noninvasive, deep subdiffraction imaging technique remains challenging. Here, we demonstrate THz near-field microscopy using a reconfigurable spintronic THz emitter array (STEA) based on the computational ghost imaging principle. By illuminating an object with the reconfigurable STEA followed by computing the correlation, we can reconstruct an image of the object with deep subdiffraction resolution. By applying an external magnetic field, in-line polarization rotation of the THz wave is realized, making the fused image contrast polarization-free. Time-of-flight (TOF) measurements of coherent THz pulses further enable objects at different distances or depths to be resolved. The demonstrated ghost spintronic THz-emitter-array microscope (GHOSTEAM) is a radically novel imaging tool for THz near-field imaging, opening paradigm-shifting opportunities for nonintrusive label-free bioimaging in a broadband frequency range from 0.1 to 30 THz (namely, 3.3–1000 cm−1).Microscopy: imaging ‘ghosts’ more clearly with terahertz wavesA modification of the technology called terahertz near-field microscopy brings improvements in resolution and speed for biological and medical imaging and nondestructive materials testing. Terahertz waves lie between the microwave and infra-red regions of the electromagnetic spectrum. The improved ‘ghost-imaging’ procedure was developed by researchers in China, Singapore and the USA, led by Li-Guo Zhu at the China Academy of Engineering Physics. In ghost imaging the illuminating radiation is split into one beam that interacts with the object being studied and another beam that does not. The so-called ghost image of the object is then constructed by computational comparison of the different behaviour of the two beams. The innovation depends on gaining enhanced control of the structure of the terahertz radiation using a system called a spintronic terahertz emitter array.

Purpose. The purpose of the current meta-analysis was to evaluate whether multidisciplinary team improved overall survival of colorectal cancer. Methods. PubMed, EMBASE, and Cochrane Library database were searched from inception to October 25, 2020. The hazard ratio (HR) and 95% confidence (CI) of overall survival (OS) were calculated. Results. A total of 11 studies with 30814 patients were included in this meta-analysis. After pooling the HRs, the MDT group was associated with better OS compared with the non-MDT group (HR=0.81, 95% CI 0.69-0.94, p=0.005). In subgroup analysis of stage IV colorectal cancer, the MDT group was associated with better OS as well (HR=0.73, 95% CI 0.59-0.90, p=0.004). However, in terms of postoperative mortality, no significant difference was found between MDT and non-MDT groups (OR=0.84, 95% CI 0.44-1.61, p=0.60). Conclusion. MDT could improve OS of colorectal cancer patients.

PurposeThe purpose of this paper is to propose and empirically test a model encompassing antecedents of webrooming, an emerging shopping behaviour in omnichannel retailing. This study delineates the impacts of shopping motivation, perceived channel-related benefits and costs on webrooming intention.Design/methodology/approachA questionnaire-based survey was conducted using a purposive sampling technique. A total of 300 responses were collected, and data were analysed using Partial Least Square Structural Equation Modelling.FindingsShopping motivation, such as efficiency shopping and bargain hunting, negatively influenced webrooming intention. Immediate possession positively influenced webrooming intention. With regard to perceived costs of webrooming, purchase effort and expected price loss negatively influenced webrooming intention. An additional exploratory analysis uncovered the moderating role of efficiency shopping.Originality/valueThis study provides empirical evidence for the antecedents of webrooming intention and expands the understanding of this emerging yet largely unexplored cross-channel behaviour.

The nuclear receptor farnesoid-X-receptor (FXR) plays an essential role in bile acid, glucose, and lipid homeostasis. In the last two decades, several diseases, such as obesity, type 2 diabetes, nonalcoholic fatty liver disease, cholestasis, and chronic inflammatory diseases of the liver and intestine, have been revealed to be associated with alterations in FXR functions. FXR has become a promising therapeutic drug target, particularly for enterohepatic diseases. Despite the large number of FXR modulators reported, only obeticholic acid (OCA) has been approved for primary biliary cholangitis (PBC) therapy as FXR modulator. In this review, we summarize the structure and function of FXR, the development of FXR modulators, and the structure–activity relationships of FXR modulators. Based on the structural analysis, we discuss potential strategies for developing future therapeutic FXR modulators to overcome current limitations, providing new perspectives for enterohepatic and metabolic diseases treatment.

PurposeThe purpose of this paper is to identify the continuance usage of livestreaming commerce. The proposed antecedents of livestreaming commerce continuance usage are social presence, perceived crowdedness, need for arousal, susceptibility to informational influence, and perceived value, whilst trust in broadcasters is treated as the moderating factor.Design/methodology/approachA survey was conducted using a questionnaire designed specifically for this purpose, which was completed by 388 Malaysian consumers aged 26–40 years who have prior experience with livestreaming commerce. The authors tested the framework using the partial least squares structural equation modelling (PLS-SEM) technique and complementary by performing artificial neural network (ANN) analysis.FindingsThe results indicate several significant relationships, whereby social presence, perceived crowdedness, susceptibility to informational influence, and trust in broadcasters significantly influence perceived value, whereas perceived value significantly influences continuance intention. In addition, trust in broadcasters moderates the relationship between perceived value and continuance intention.Originality/valueThe current study adds significantly to the body of knowledge about livestreaming by examining the direct determinants of perceived value and thus delineating how perceived value influences continuance intention. The findings yielded also illustrate the role of trust in broadcaster as the moderator of the link between perceived value and continuance intention.

PurposeThe recent livestreaming commerce has magnified the role of influencer marketing, where the influencers are partnering with brands for product promotion. This study examines the impact of influencer attributes, interaction strategies and parasocial relationships on impulsive buying in livestreaming commerce.Design/methodology/approachA survey with 368 livestreaming commerce users was analyzed using the symmetric-thinking approach – partial least squares structural equation modeling (PLS-SEM) and asymmetric thinking approach – fuzzy set qualitative comparative analysis (fsQCA).FindingsThe results of PLS-SEM indicate that influencer trustworthiness, influencer interactivity and self-disclosure determine parasocial relationships, which in turn influence impulsive buying. The fsQCA finding returned three configurations with various combinations of the causal conditions (i.e. influencer attributes, interaction strategies, parasocial relationships, perceived fit uncertainty and perceived quality uncertainty) explaining the formation of impulsive buying.Originality/valueThese findings provide unique linear and nonlinear insights to explain the combinatory effects of influencer attributes, interaction strategies, parasocial relationships, perceived fit uncertainty and perceived quality uncertainty on impulsive buying in livestreaming commerce.
