AbstractWith increasing evidence supporting the use of biometric identification methods for authentication, this study aims to enhance our understanding of the factors influencing the acceptance of and resistance to facial recognition payment (FRP) systems. To provide a comprehensive review of these factors, we conducted a systematic literature review (SLR) of empirical studies. We examined 22 key research articles from an initial pool of 1372 publications, identifying 37 factors that influence consumer acceptance or resistance to FRP. These factors were categorized into usage‐related aspects, attitudes and evaluations, user‐related traits, privacy and security concerns, and other factors. Our findings reveal that the most frequently cited factors include performance expectancy, effort expectancy, perceived usefulness, and perceived ease of use. These factors are crucial in contexts where FRP can increase productivity by providing prompt information and effective assistance. This research proposes a collective model for understanding the determinants of FRP acceptance or resistance, integrating theoretical frameworks and empirical findings. The model emphasizes the context‐dependency of user acceptance, highlighting the importance of addressing both technological and psychological factors. It incorporates usage characteristics, user characteristics, and privacy and security concerns, which are mediated by attitudes and evaluations. The proposed model provides a comprehensive framework for understanding and addressing the factors influencing acceptance of and resistance to FRP, guiding FRP service providers in developing effective strategies to increase user adoption, with future research needed to refine and assess the model further.

Purpose
This study aims to examine how virtual influencers (VIs) affect purchase intentions in tourism and hospitality e-commerce live streaming (THCLS) by focusing on the roles of VIs' source credibility, trust in products, trust in VIs, emotional engagement, parasocial relationships and influencer–product congruence.

Design/methodology/approach
Survey data from 416 active viewers of VIs in THCLS were analysed using partial least squares structural equation modelling.

Findings
This study highlights the importance of the VIs' source credibility, which positively affects trust in the product, trust in VIs and emotional engagement. However, source credibility does not have a positive impact on parasocial relationships. Trust in products positively influences trust in VIs. Emotional engagement and trust in VIs significantly influence parasocial relationships, which, positively affects purchase intentions. Influencer–product congruence strengthens the link between parasocial relationships and purchase intentions but does not moderate the relationship between trust in VIs and purchase intentions. No significant gender differences were observed, although minor discrepancies were noted in the effect of trust in products on trust in VIs. The importance–performance map analysis revealed that parasocial relationships are the most important factor influencing purchase intentions, while influencer–product congruence has the highest performance, trust in products is the least important and VIs' source credibility has the lowest performance.

Practical implications
This study provides actionable insights for marketers leveraging VIs in the THCLS sector, emphasizing strategies to enhance VI credibility, foster parasocial relationships, ensure influencer–product congruence and adopt gender-neutral marketing approaches to effectively influence purchase intentions.

Originality/value
This study offers theoretical and practical insights into the role of VIs in THCLS, illuminating their impact on consumer behaviour and purchase intentions.

Previous researchers of impression management have focused on the tactics of supervisor-targeted ingratiation, self-promotion, and exemplification, and neglected those targeting coworkers. Thus, we focused on the supplication tactics that employees use toward coworkers. Data were collected
from 238 supervisor–subordinate dyads working at technology companies in Taiwan. Results showed that the higher the self-efficacy, the less likely employees were to use supplication tactics. This negative relationship was also stronger when leader–member exchange (LMX) quality
was high. However, when employees used supplication tactics, high LMX did not buffer supervisors' negative assessment of their organizational citizenship behavior (OCB). Thus, employees' supplication tactics damaged supervisors' evaluation of their OCB. Theoretical and practical implications
are discussed.

AbstractIntroductionAs people with HIV age, prevention and management of other communicable and non‐communicable diseases (NCDs) will become increasingly important. Integration of screening and treatment for HIV and NCDs is a promising approach for addressing the dual burden of these diseases. The aim of this study was to assess the epidemiological impact and cost‐effectiveness of a community‐wide integrated programme for screening and treatment of HIV, hypertension and diabetes in Kenya.MethodsCoupling a microsimulation of cardiovascular diseases (CVDs) with a population‐based model of HIV dynamics (the Spectrum), we created a hybrid HIV/CVD model. Interventions were modelled from year 2019 (baseline) to 2023, and population was followed to 2033. Analyses were carried at a national level and for three selected regions (Nairobi, Coast and Central).ResultsAt a national level, the model projected 7.62 million individuals living with untreated hypertension, 692,000 with untreated diabetes and 592,000 individuals in need of ART in year 2018. Improving ART coverage from 68% at baseline to 88% in 2033 reduced HIV incidence by an estimated 64%. Providing NCD treatment to 50% of diagnosed cases from 2019 to 2023 and maintaining them on treatment afterwards could avert 116,000 CVD events and 43,600 CVD deaths in Kenya over the next 15 years. At a regional level, the estimated impact of expanded HIV services was highest in Nairobi region (averting 42,100 HIV infections compared to baseline) while Central region experienced the highest impact of expanded NCD treatment (with a reduction of 22,200 CVD events). The integrated HIV/NCD intervention could avert 7.76 million disability‐adjusted‐life‐years (DALYs) over 15 years at an estimated cost of $6.68 billion ($445.27 million per year), or $860.30 per DALY averted. At a cost‐effectiveness threshold of $2,010 per DALY averted, the probability of cost‐effectiveness was 0.92, ranging from 0.71 in Central to 0.92 in Nairobi region.ConclusionsIntegrated screening and treatment of HIV and NCDs can be a cost‐effective and impactful approach to save lives of people with HIV in Kenya, although important variation exists at the regional level. Containing the substantial costs required for scale‐up will be critical for management of HIV and NCDs on a national scale.

BACKGROUND: Presently, the global spread of COVID‐19 is still going on, with more than 0.6 million new cases confirmed per day (as of November 20, 2021). However, since China entered a post‐epidemic phase in mid‐March 2020, the daily number of new domestic infections in the Chinese mainland has been maintained at almost zero or single digits, which was attributed to a series of effective measures for COVID‐19 prevention and control adopted by the Chinese government. Among these measures, SARS‐CoV‐2 nucleic acid testing holds key role for the timely confirmation and isolation of the infections to prevent further transmission. METHODS: Referring to the national policy requirements, since April 30, 2020, The Affiliated Hospital of Qingdao University has conducted SARS‐CoV‐2 nucleic acid testing in its PCR laboratory for patients and social workers, as well as for environmental monitoring and employee screening. As of mid‐November 2020, the daily amount of single‐tube samples for nucleic acid testing rose above 4,000. RESULTS: In this article, a rapid and highly effective approach for SARS‐CoV‐2 nucleic acid daily testing is presented, allowing five technicians to complete nucleic acid testing in 6,500 single‐tube samples in one day with a high level of quality. Using this approach, since the samples entered the PCR laboratory, all testing results were reported in 2.5–3 h with satisfactory quality control and precise reporting criterion as prerequisites. CONCLUSION: This testing approach provides a referable workflow for other testing institutions and is expected to play an important role in COVID‐19 prevention and control.
