Understanding consumers’ live-streaming shopping from a benefit–risk perspective
Authors: Chen Chunfeng , Zhang Depeng 
Published: April 2023

Purpose
The rapid development of live-streaming commerce has increased companies’ marketing effectiveness. While previous studies have explored the effects of its technical features on consumers, the effects of marketing-related factors remain unknown. This study aims to investigate the effects of the marketing elements of live-streaming commerce on consumers’ purchase intentions.

Design/methodology/approach
The research model is derived from the Yale model and the benefit–risk framework. To test the study hypotheses, data were collected through a questionnaire survey of 392 live-streaming shoppers and analyzed using SmartPLS.

Findings
The empirical results indicate that broadcaster competence and online crowding increase consumers’ perception of price attractiveness while reducing their perceived uncertainty. Information diagnosticity also reduces consumers’ perceived uncertainty. Furthermore, purchase intention is positively and negatively affected by perceived price attractiveness and perceived uncertainty, respectively. Finally, product scarcity moderates the relationships between broadcaster competence, online crowding, information diagnosticity, perceived price attractiveness and perceived uncertainty.

Originality/value
The study identifies the different marketing elements in live-streaming commerce and their effects on consumers’ value evaluations and purchase intentions. The findings provide comprehensive insights into the antecedents of live-streaming shopping and offer new perceptions and recommendations for practitioners.
Virtually present others and their influence on complainants’ follow-ups and firm response
Authors: Rios Rosa E. , Riquelme Hernan E. , Comai Alessandro 
Published: April 2023

PurposeThe purpose of this empirical research is to investigate the influence of interactive virtually present others (VPOs) on a firm response and customers’ reiterated complaints (follow-ups) during service failures. This research follows up on previous experimental studies that suggest VPOs affect the focal customers’ complaint intention.Design/methodology/approachMore than 16,000 posts (of complaints and complainants’ follow-ups) on 13 airline Facebook pages were analyzed using partial least squares.FindingsThis empirical study found that customers’ complaints are attended to the extent the complaints are followed up with more comments as supported by VPOs suggesting a contagion effect. Besides, it appears, the squeaky wheel is the one that gets the grease. The interactive virtual presence of others does not have an effect on a firm response toward them, despite their support to complainants and calling the airline to act.Originality/valueTo date, previous experimental studies have only featured a single VPO in potential complainants’ responses; however, in this empirical study the authors take into consideration the interaction of several VPOs in the service failure. Also, the focus is on the influence of VPOs on customers' complaints rather than the other way around.
Hedonic adaptation to preferential treatment: the moderating effect of the structural characteristics of loyalty programs
Authors: Fu Xiaorong , Ren Xiangming 
Published: April 2023

Purpose
As internet dividends are gradually disappearing, loyalty programs have become the panacea for monetizing traffic, attracting new customers and retaining existing customers. Improving their effectiveness has thus become key to enterprises’ market competitiveness. However, member customers’ hedonic adaptation to this relationship strategy undermines its effectiveness. Based on the hedonic adaptation theory, this study aims to analyze the process of member customers' hedonic adaptation to preferential treatment in loyalty programs and explore the boundary conditions of alleviating this effect.

Design/methodology/approach
This study surveyed 271 member customers in China and tested the hypothesized relationships using structural equation modeling and multigroup analysis.

Findings
Preferential treatment suffers from hedonic adaptation to member customer engagement and customer gratitude, and customer tenure is a key condition for these effects. Customer gratitude is an intermediary mechanism that explains the hedonic adaptation effect of preferential treatment to member customers engagement. In addition, the structural characteristics of loyalty programs form the boundary condition that alleviates hedonic adaptation. The authors found that high-tier and -payment strategies are more likely to mitigate hedonic adaptation of preferential treatment to customer gratitude.

Originality/value
This study elucidates the factors that influence the effectiveness of preferential treatment and provides constructive insights into customer relationship management and for improving enterprise performance.

Published: April 2023

Purpose
The durability of concrete containing recycled aggregates, sourced from concrete specimens that have been tested in laboratory testing facilities, remains understudied. This paper aims to present the results of experiments investigating the effect of incorporating such type of concrete waste on the strength and durability-related properties of concrete.

Design/methodology/approach
A total of 77 concrete cylinders sized Ø100 × 200 mm with varying amount of recycled concrete aggregate (RCA) (0%–100% by volume, at 25% increments) and maximum aggregate size (12.5, 19.0 and 25.0 mm) were fabricated and tested for slump, compressive strength, sorptivity and electrical resistivity. Disk-shaped specimens, 50-mm thick, were cut from the original cylinders for sorptivity and resistivity tests. Analysis of variance and post hoc test were conducted to detect statistical variability among the data.

Findings
Compared to regular concrete, a reduction of slump (by 18.6%), strength (15.1%), secondary sorptivity (31.5%) and resistivity (17.0%) were observed from concrete containing 100% RCA. Statistical analyses indicate that these differences are significant. In general, an aggregate size of 19 mm was found to produce the optimum value of slump, compressive strength and sorptivity in regular and RCA-added concrete.

Originality/value
The results of this study suggest that comparable properties of normal concrete were still achieved by replacing 25% of coarse aggregate volume with 19-mm RCA, which was processed from laboratory-tested concrete samples. Therefore, such material can be considered as a potential and sustainable alternative to crushed gravel for use in light or nonstructural concrete construction.
How influencers’ social media posts have an influence on audience engagement among young consumers
Authors: Fan Fei , Chan Kara , Wang Yan , Li Yupeng , Prieler Michael 
Published: April 2023

Purpose
Online influencers are increasingly used by brands around the globe to establish brand communication. This study aims to investigate the characteristics of social media content in terms of presentation style and brand communication among online influencers in China. The authors identified how characteristics of social media posts influence young consumers’ engagement with the posts.

Design/methodology/approach
The authors analyzed 1,779 posts from the Sina Weibo accounts of ten top-ranked online influencers by combining traditional content analysis with Web data crawling of audience engagement with social media posts.

Findings
Online influencers in China more frequently used photos than videos to communicate with their social media audience. Altogether 8% and 6% of posts carried information about promotion and event, respectively. Posts with promotional incentives as well as event information were more likely to engage audiences. Altogether 22% of the sampled social media posts mentioned brands. Posts with brand information, however, were less likely to engage audiences. Furthermore, having long text is more effective than photos/images in generating likes from social media audiences.

Originality/value
Combining content analysis of social media posts and engagement analytics obtained via Web data crawling, this study is, to the best of the authors’ knowledge, one of the first empirical studies to analyze influencer marketing and young consumers’ reactions to social media in China.

ObjectivesTo evaluate patients with clinical (c)T4 prostate cancer (PCa), which represent both a heterogenous and understudied population, who often present with locally advanced disease and obstructive symptoms causing significant morbidity and mortality. We analysed whether receiving definitive local therapy influenced symptomatic and oncological outcomes.MethodsRetrospective analysis of 154 patients with cT4 PCa treated at a single institution in 1996–2020. Systemic therapy with or without local treatment (surgery, radiotherapy [RT], or both). Uni‐ and multivariate analyses of associations between clinicopathological features (including obstructive symptoms) and receipt of local therapy on overall survival (OS) and disease control were done with Cox regression.ResultsThe median follow‐up time was 5.9 years. Most patients had adenocarcinoma (88%), Gleason score 9–10 (77%), and median baseline prostate‐specific antigen (PSA) of 20 ng/mL; most (54%) had metastatic cT4N0–1M1 disease; 24% regionally advanced cT4N1M0, and 22% localised cT4N0M0. Local therapies were RT (n = 44), surgery (n = 28), or both (n = nine). Local therapy was associated with improved OS (hazard ratio [HR] 0.3, P < 0.001), longer freedom from local recurrence (HR 0.39, P = 0.002), less local progression (HR 0.41, P = 0.02), fewer obstructive symptoms with progression (HR 0.31, P = 0.01), and less death from local disease (HR 0.25, P = 0.002). On multivariate, local therapy was associated with improved survival (HR 0.58, P = 0.02), and metastatic disease (HR 2.93, P < 0.001) or high‐risk pathology (HR 2.05, P = 0.03) was associated with worse survival.ConclusionDefinitive local therapy for cT4 PCa was associated with improved symptomatic outcomes and survival even among men with metastatic disease. Pending prospective evaluation, these findings support definitive treatment with local therapy for cT4 disease in select cases.
Oral health promotion through health‐promoting schools in developing countries: A scoping review
Authors: Elsadek Yasmen E. , Baker Sarah R. 
Published: April 2023

AbstractObjectivesTo explore and assess what is known about oral health promotion through health‐promoting primary schools in developing countries.MethodsA scoping review was conducted using the Arksey & O'Malley framework. Web of Science, PubMed, Scopus and Cochrane Library were searched, followed by the reference lists of the resulting studies. The UN classification of developing countries was used to define the countries included and the search was between 1986 and 2021. Quality assessment was carried out using Joanna Briggs Institute's quality appraisal tools.ResultsThe search resulted in 33 studies of which almost half were randomized controlled trials. The oral health promotion strategies were oral health education (n = 16) delivered by teachers, parents or peers, or multicomponent involving both toothbrushing (n = 15) and dietary components (n = 2). Most of the included studies were conducted in Asia (n = 25/33).ConclusionsFindings suggested that comprehensive, multicomponent theory‐based oral health promotion showed improvements in oral health outcomes of schoolchildren, particularly if delivered using a whole‐school approach. However, further research on feasibility and implementation of oral health promotion through health‐promoting primary schools in developing countries should be considered.

Published: April 2023

AbstractIn this paper, we tackle the challenging problem of rendering real‐world 360° panorama videos that support full 6 degrees‐of‐freedom (DoF) head motion from a prerecorded omnidirectional stereo (ODS) video. In contrast to recent approaches that create novel views for individual panorama frames, we introduce a video‐specific temporally‐consistent multi‐sphere image (MSI) scene representation. Given a conventional ODS video, we first extract information by estimating framewise descriptive feature maps. Then, we optimize the global MSI model using theory from recent research on neural radiance fields. Instead of a continuous scene function, this multi‐sphere image (MSI) representation depicts colour and density information only for a discrete set of concentric spheres. To further improve the temporal consistency of our results, we apply an ancillary refinement step which optimizes the temporal coherency between successive video frames. Direct comparisons to recent baseline approaches show that our global MSI optimization yields superior performance in terms of visual quality. Our code and data will be made publicly available.
Discrete wavelet transform based branched deep hybrid network for environmental noise classification
Authors: Shah Syed Aamir Ali , Bais Abdul , Alashaikh Abdulaziz , Alanazi Eisa 
Published: April 2023

SummaryWith ever growing urbanization, the environmental noise is becoming hazardous. Vehicular traffic, locomotives, heavy machinery in industry, and construction processes are the major sources of noise pollution. It has adverse effects on the health of humans as well as that of the wild life. World Health Organization (WHO) puts noise pollution as the second major cause of illness due to environmental reasons. The effects of noise pollution on the quality of life are usually ignored. Due to this reason it is common, even in the first world countries, to have the WHO's peak noise standards violated in residential areas. Therefore, there is a need to have a real time, portable and easy to replicate, mechanism to monitor the noise sources. In this work, we propose a novel architecture of a deep neural network to classify a 10‐class environmental noise data called URBANSOUND8K. This network is comprised of three components, (1) one dimensional two level Discrete Wavelet Transform (DWT) component, (2) branched component for feature extraction through auto‐encoders, and (3) LSTM and fully‐connected layers based classification component. With all components combined, we call this network DWTNet. By embedding the DWT component as a part of network, we eliminate the need of prior data conversion into spectral and/or spectro‐temporal domains. The efficiency of DWTNet is comparable to the state of the art networks with significantly lower number of trainable parameters. We analyze the contribution of classification accuracy. We further study some of the classification results individually and show that some of the mis‐classifications are actually multi‐class classifications with distributed decision confidence.
Clear cell tumor with melanocytic differentiation and MITF::CREM translocation

Published: April 2023

AbstractIn addition to melanoma, a large and diverse family of tumors shows melanocytic differentiation. The best characterized member of this family is clear cell sarcoma, which is characterized by EWSR1::ATF1 and EWSR1::CREB1 fusions. These fusions drive the transcription of MITF, the master regulator of melanocytic differentiation. Clear cell tumor with melanocytic differentiation and MITF::CREM translocation is a recently described tumor with some similarities to clear cell sarcoma. However, only a single case has been reported. Here, we describe a second molecularly proven case that arose on the scalp of a newborn baby. In contrast to the prior reported case, the current case showed predominantly high‐grade cytomorphologic features with only focal clear cell areas. Similar to the prior case, the tumor showed immunohistochemical evidence of neural crest origin/differentiation with prominent melanocytic differentiation. The fusion breakpoints were also similar and preserved the transcriptional activation domain of CREM, suggesting that CREM hyperactivity is a major feature of this tumor type. The current tumor showed a short‐interval recurrence. These results expand the clinical and pathologic spectrum of this potentially new entity.

AbstractObesity is a chronic, progressive and relapsing disease with a rising global prevalence associated with increased morbidity and mortality and reduced quality of life. Treatment of obesity requires a comprehensive medical approach that includes behavioural interventions, pharmacotherapy and bariatric surgery. The degree of weight loss with all approaches is highly heterogeneous, and long‐term weight maintenance remains challenging. For years, antiobesity medications have been limited in number, often delivering meagre efficacy and raising numerous safety concerns. Therefore, there is a need for the development of highly efficacious and safe new agents. Recent insights into the complex pathophysiology of obesity have increased our understanding of intervenable targets for pharmacotherapies to treat obesity and improve weight‐related cardiometabolic complications, namely, type 2 diabetes, hyperlipidaemia and hypertension. As a result, novel potent therapies have emerged, such as semaglutide, a glucagon‐like peptide‐1 receptor agonist (GLP‐1RA) recently approved for the treatment of obesity. Semaglutide 2.4 mg once weekly significantly reduces body weight by approximately 15%, with simultaneous improvement in cardiometabolic risk factors and physical functioning in people with obesity. Tirzepatide, the first dual glucose‐dependent insulinotropic polypeptide (GIP)/GLP‐1RA, has recently demonstrated that body weight reduction exceeding 20% in people with obesity and coupled with improved cardiometabolic measures is feasible. Thus, these novel agents promise to narrow the gap between the weight‐loss effects of behaviour interventions, previous pharmacotherapies, and bariatric surgery. In this narrative review, we highlight established and emerging therapeutic treatments for long‐term obesity management and position them in a framework according to their weight loss effects.

Published: April 2023

AbstractBackgroundTelepsychiatry has the potential to facilitate access to mental health services for young people with first‐episode of psychosis (FEP); however, limited attention has been given regarding the perceptions of mental health providers in this regard.ObjectiveTo assess service providers' perceptions on the use of telepsychiatry and changes over time.MethodsLongitudinal survey (conducted at two time points) of 26 service providers, including physicians, nurses, social workers, occupational therapists, and peer support workers, recruited from a specialized program for FEP providing telepsychiatry services through REACTS (videoconferencing platform).ResultsResponses during the initial and the follow‐up survey were similar. Most participants used REACTS nine times or more, with more than half reporting that sessions lasted more than 30 min. Over time, there was a trend towards higher frequency of use and lower duration of sessions. The majority perceived REACTS as safe and easy to use and indicated they would recommend REACTS to colleagues. Although participants reported some issues related to set‐up and initial use, internet accessibility, and sound and image, most of these concerns decreased during follow‐up. Participants appreciated the usability and utility of REACTS, and reported several benefits of telepsychiatry, including facilitating client engagement, assessment and continuity.ConclusionsService providers expressed positive perceptions regarding the use of telepsychiatry. Despite analysis being limited to a small sample, this study raises awareness of telepsychiatry's value and feasibility for offering services to young populations with FEP and the importance of conducting research on clinician perspectives in this regard.
Metabolic efficiency reshapes the seminal relationship between pathogen growth rate and virulence
Authors: Lindsay Richard J. , Holder Philippa J. , Talbot Nicholas J. , Gudelj Ivana 
Published: April 2023

AbstractA cornerstone of classical virulence evolution theories is the assumption that pathogen growth rate is positively correlated with virulence, the amount of damage pathogens inflict on their hosts. Such theories are key for incorporating evolutionary principles into sustainable disease management strategies. Yet, empirical evidence raises doubts over this central assumption underpinning classical theories, thus undermining their generality and predictive power. In this paper, we identify a key component missing from current theories which redefines the growth–virulence relationship in a way that is consistent with data. By modifying the activity of a single metabolic gene, we engineered strains of Magnaporthe oryzae with different nutrient acquisition and growth rates. We conducted in planta infection studies and uncovered an unexpected non‐monotonic relationship between growth rate and virulence that is jointly shaped by how growth rate and metabolic efficiency interact. This novel mechanistic framework paves the way for a much‐needed new suite of virulence evolution theories.
