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.

The unprecedented interactivity of social media has empowered social media influencers to develop close relationships with their followers, and such relationships carry important marketing implications for social media influencers and brands. The present study examines the antecedents and outcomes of followers’ parasocial relationships with social media influencers. Drawing upon the theoretical lens of parasocial interaction theory, influence framework, and attribution framework, the study proposes and empirically tests the effects of social media influencers’ influence attempts on parasocial relationships, and the subsequent downstream outcomes of perceived endorser motives and consumer purchase intentions. Using a survey-based approach, the study collected 361 usable responses, and data were analyzed using partial least squares structural equation modeling. The study found that (1) influence attempts (i.e., attractiveness, prestige, and expertise) positively influence parasocial relationships, whereas (2) parasocial relationships negatively influence perceived endorser motive (self-serving), which in turn (3) reduces purchase intention, and (4) self-discrepancy moderates the relationships between influence attempts and parasocial relationships. Two post-hoc exploratory analyses uncovers the impacts of number of followers and gender in the proposed relationships. Theoretical and practical implications are discussed.
Terahertz (THz) radiation, which occupies a relatively unexplored portion of the electromagnetic spectrum between the mid-infrared and microwave bands, offers innovative sensing and imaging ...technologies that can provide information unavailable through conventional methods such as microwave and X-ray techniques. With the advancement of THz technologies, THz sensing and imaging will impact a broad range of interdisciplinary fields, including chemical and biological detections and identifications. In particular, THz radiation offers the opportunity for transformational advances in defense and security. Recent work shows that THz technologies are promising for the standoff detection and identification of explosive targets.
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.

Purpose The 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/approach A 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. Findings Shopping 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/value This study provides empirical evidence for the antecedents of webrooming intention and expands the understanding of this emerging yet largely unexplored cross-channel behaviour.
Abstract
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

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.
Despite the growing body of research exploring factors associated with service robot adoption, the existing comprehension of this emerging technology remains largely fragmented. Previous studies have ...largely focused on the “net effect” between variables, leaving the complexity of consumer behavior uninvestigated. Building on relevant literature and complexity theory, this study intends to consolidate the fragmented views of service robot adoption literature by examining how human-likeness (i.e., anthropomorphism and perceived intelligence), technology-likeness (i.e., performance expectancy, hedonic motivation, and privacy risks), and consumer personalities (i.e., extraversion and openness to experience) combined as causal configurations to explain the behavioral intention to use service robots. Fuzzy set qualitative comparative analysis (fsQCA) was employed to analyze data from a sample of 566 Taiwanese consumers. The results from fsQCA results suggest that multiple, distinct, and equally effective combinations of human-like, technology-like, and consumer features exist to achieve high intention to use service robots. Four solutions are presented that lead to high adoption intention. This study contributes to the artificial intelligence literature by adopting a novel methodological approach to unveil the complexity behind the adoption of service robots. It also offers practical guidance for robot manufacturers and service managers to optimize the combination of human-likeness and technology-likeness in correspondence to consumer personalities for a successful service robots’ implementation.
•This study adopts a holistic and unifying approach to understand service robot adoption.•We employed a novel analytical method (fSQCA) and complexity theory to unveil the complexity behind the adoption decision.•The fsQCA results show that none of the factors are necessary conditions for achieving a high level of behavioral intention.•Four combinations of the human-like, technology-like, and consumer features can lead to a high level of behavioral intention.•We offer guidance for managers on how to tailor robot characteristics in consideration of consumer personalities.
