Published: November 2024

PurposeThe process of introducing a new robotic technology into a service system is complex, and its impacts on work practices can be challenging. By adopting a system perspective, this study investigates how human–robot collaboration (HRC) transforms work practices (i.e. customer care).Design/methodology/approachWe conducted a two-year longitudinal analysis of an international company specializing in natural health products, examining changes in customer care practices following the introduction of chatbots. The study leverages expansive learning theory, which emphasizes activity systems and the transformations that occur within them, to trace the integration of robots and their effects on work practices.FindingsThe findings reveal that HRC enhances customer care practices by creating a human–robot activity system organized around shared goals. This system, mediated by tools, rules and the community, evolves through expansive learning dynamics. The process begins by identifying and addressing the contradictions and tensions between current human work practices and robotic capabilities, often revealing challenges and opportunities to improve HRC.Originality/valueThis research offers a novel conceptualization of the systemic and dynamic nature of HRC by placing it within broader frames of activity systems and expansive learning. Collaborations between humans and robots entail an expansive performativity that extends beyond the traditional roles or tasks of either actor or actant. It spans a diverse range of objects, tools, procedures and institutional setups, culminating in transformations of customer care practices.

PurposeThis study explores the effects of virtual streamer characteristics, virtual scene characteristics and streamer image-scene fit on users’ watching intention from the perspective of flow experience.Design/methodology/approachThe survey data for this study were collected from the QQ fan group of virtual streamers between November 26th 2022 and December 5th 2022. The authors survey 274 viewers who have experience of watching virtual streaming and employ the partial least squares structural equation model to test the research hypotheses.FindingsAmong the characteristics of virtual streamers, interactivity significantly influences users’ perceived enjoyment and concentration, while vividness only affects perceived enjoyment. In addition, the novelty of the virtual scene has a notable impact on users’ perceived enjoyment and concentration, whereas aesthetic appeal serves as an important indicator solely for concentration. Furthermore, the virtual streamer image-scene fit also affects users’ perceived enjoyment and concentration. Finally, perceived enjoyment and concentration equally contribute to users' watching intention.Originality/valueThis study explores the impact of virtual streamer characteristics, virtual scene characteristics and streamer image-scene fit on users’ watching intention, which enriches the research on user behavioral intention in virtual streaming. Additionally, this study attempts to combine the stimulus-organism-response (S-O-R) model and flow theory in the field of virtual streaming, expanding the research areas. Finally, this study also provides valuable insights for virtual streamers and virtual streaming platforms. By enhancing their virtual personas and optimizing their streaming strategies, virtual streamers can more effectively retain users and maintain audience engagement. Meanwhile, virtual streaming platforms can gain a deeper understanding of user preferences, enabling them to launch high-quality events that sustain user popularity. These efforts collectively contribute to the advancement of the virtual streaming industry.

Published: November 2024

PurposeOwing to the limitations of traditional infectious disease dynamic systems in accurately encapsulating the nuances of China’s dynamic epidemic prevention policies and considering the varying sensitivity of local governments to the unfolding of public health emergencies (PHEs), this paper introduces a novel infectious disease dynamic system.Design/methodology/approachThis system, rooted in the distinct characteristics of infectious diseases and nuanced prevention and control measures, leverages a learning model for enhanced precision. It intricately incorporates factors such as the infectivity in sealed and controlled areas and the role of asymptomatic patients, thereby refining the dynamics of isolation, sealing, control and the transition from asymptomatic to confirmed cases. Employing the Markov Chain Monte Carlo (MCMC) parameter estimation approach significantly augments the accuracy in pinpointing the valid parameters of disease spread. Empirical analysis was meticulously carried out, using data from the Shanghai epidemic from 1 Mar 2022 to 1 Jul 2022.FindingsThis analysis not only illuminates the profound impact of control efforts on the trajectory of the epidemic but also underscores the pivotal role of social distancing in curbing the rapid transmission of infectious diseases. Furthermore, it reveals that an accelerated detection rate during the swift spread and peak of the epidemic paradoxically leads to a surge in confirmed cases and a consequent strain on medical resources, thereby impeding the pace of medical intervention.Originality/valueA stage-wise dissection of the Shanghai epidemic and comparative analyses against the evolution profiles in ASEAN countries elucidates the five stages of PHE risk evolution in alignment with the crisis lifecycle theory. These stages encompass hidden transmission, multi-point dissemination, multi-chain parallelism, rapid spread, fluctuation rebound and multi-community spread, each presenting unique challenges and dynamics in the control and management of the epidemic.
Petrol Prices, Food Prices, and Inflation Perceptions in New Zealand—Evidence From a Threshold Analysis
Authors: Vatsa Puneet , Pino Gabriel 
Published: November 2024

ABSTRACTInflation perceptions shape inflation expectations. However, little is known about the factors influencing these perceptions. In this study, we address this gap by employing threshold regressions to analyze the associations between changes in petrol and food prices—two of the most conspicuous prices—and inflation perceptions in New Zealand. Findings reveal a positive association between petrol and food price inflation on the one hand and inflation perceptions on the other, with some evidence suggesting closer associations for food price inflation. Furthermore, the relationships do not change when high inflation rates are considered instead of low inflation rates. Finally, inflation perceptions are more closely related to petrol and food price inflation over the previous year than just the most recent quarter.
The placing of care: ordinary ethics of mobility in the Sino‐Tibetan borderlands
Authors: Ran Peter Guangpei 
Published: November 2024

This article concerns the migratory experiences of a group of Naxi in the Sino‐Tibetan borderlands, framed by the drastic social changes brought about by market reform in the past few decades in rural China. The unprecedented level of mobility of a younger generation leaving home for education or work leads to tension between their deep ties to local lifeworlds and a yearning for prosperity envisioned elsewhere. The article looks at the ethical and existential implications of their routinized movements between home villages and nearby cities, which involve both those moving and those left behind in caring relationships. I argue that such movements negotiate a place‐based and gendered relationality that defines people's responsibilities for each other across space and time – including both humans and ancestral spirits – despite living through the fragmenting effects of displacement and separation.

Published: November 2024

AbstractLipids perform a diverse and unique array of functions in insects. Lipases are key enzymes in lipid metabolism, and their metabolic products are crucial for development and reproduction of insects. Here, a total of 110 lipase genes were identified in the genome of Spodoptera frugiperda. Cluster analysis indicated that neutral lipases constitute the majority of lipases. Tissue expression profile analysis displayed that most lipase genes were highly expressed in the larval gut of S. frugiperda. Some lipases exhibited a diet‐specific expression pattern, which implied their roles in host adaptation. Key domain analysis proved that none of the neutral lipases highly expressed in the gut has an integrated lid domain, while most lipases highly expressed in the fat body contained both the integrated lid domain and β9 loop, indicating the activity loss of neutral lipases in guts. The assay of triacylglycerol (TAG) hydrolytic activity confirmed that the gut had the lowest activity when compared to that of fat body and epidermis. Interestingly, the opposite TAG hydrolytic activity trends across mating were observed between adult males and females, implying that lipase played different roles in the reproduction of both sexes. In conclusion, neutral lipases lost TAG hydrolytic activity in S. frugiperda guts, but retained the activity in fat body. Neutral lipases would play vital roles in many physiological processes in insects, especially in insect reproduction, which provides palpable targets for novel insecticide development to control insect population growth.

SummaryIntroductionThe number of tracheal intubation attempts required to reach proficiency in videolaryngoscopy with hyperangulated blades is unknown. Understanding this training requirement might guide training for clinicians who perform laryngoscopy. We therefore performed a planned sub‐analysis of a randomised controlled trial comparing tracheal intubation success with videolaryngoscopy vs. direct laryngoscopy to determine the number of tracheal intubations with a hyperangulated videolaryngoscope blade needed to provide an acceptable first‐attempt success rate.MethodsWe included clinicians from a randomised controlled trial who were familiar with direct laryngoscopy and Macintosh‐blade videolaryngoscopy but inexperienced with hyperangulated videolaryngoscopy. Cumulative sum statistics were used to generate learning curves with acceptable success rates of 85% and unacceptable success rates of 70% for the primary outcome of first‐attempt tracheal intubation success.ResultsWe included 223 clinicians (25 consultants; 35 certified registered nurse anaesthetists; 36 student registered nurse anaesthetists; 46 fellows; and 81 residents) who attempted tracheal intubation in 4312 procedures. The median (IQR [range]) number of tracheal intubations per clinician was 15 (8–25 [1–77]). First‐attempt failure was low, with only 72 failed first attempts overall, and was comparable across clinician groups. In total, 133 (60%) clinicians crossed the acceptable success rate boundary while the remaining 90 (40%) clinicians crossed neither the acceptable nor unacceptable success rate boundaries. Among clinicians who crossed the acceptance boundary, the median (IQR [range]) number of attempts for learning was 12 (12–12 [12–26]).DiscussionClinicians experienced in tracheal intubation with direct laryngoscopy but unfamiliar with hyperangulated‐blade videolaryngoscopy can achieve proficiency after approximately 12 attempts.

AbstractPurposeTo investigate if the initial treatment response can predict the 1‐year treatment outcomes in patients with neovascular age‐related macular degeneration (nAMD) treated according to the observe‐and‐plan (O&P) regimen.MethodsIn this prospective cohort study, treatment‐naïve patients with nAMD were enrolled consecutively and followed for 1 year while being treated according to the O&P regimen. The treatment response was determined initially post‐loading doses and after 1 year. The functional treatment response (fTR) was determined by the change in best corrected visual acuity, while the morphological treatment response (mTR) was assessed by central retinal thickness and the presence of sub‐ and intraretinal fluid on optical coherence tomography and categorized as good, partial, and poor responders. The relative risk (RR) of the initial treatment response for predicting 1‐year treatment response was assessed.ResultsOne hundred patients were included and 94 completed the 1‐year follow‐up. Patients with an initial good fTR and initial poor fTR had an RR of 4.1 (95% CI 1.8–9.2) and 4.3 (95% CI 2.2–8.3), respectively, of remaining in the same response category at 1 year. Similarly, patients with an initial good mTR and initial poor mTR had an RR of 3.0 (95% CI 1.8–4.8) and 8.7 (95% CI 3.0–25.1), respectively, of remaining in the same response category at 1 year.ConclusionsBoth the anatomic and visual functional response after 3 loading doses are predictive of the anatomic and functional outcomes at 1 year in patients with nAMD treated according to the O&P regimen.

Published: November 2024

ABSTRACTContextPost‐bariatric hypoglycemia (PBH) is a complication of bariatric surgery including Roux‐en‐Y gastric bypass (RYGB). It remains unclear why only some individuals develop PBH.ObjectiveTo identify clinical characteristics distinguishing post‐RYGB individuals with PBH, versus without symptomatic hypoglycemia (RYGB non‐hypo).Design and SettingCross‐sectional observational study in academic referral centre. Adults 18–70, without current diabetes, were recruited into three groups: (1) PBH (n = 39); (2) RYGB non‐hypo (n = 25); and (3) individuals without history of upper gastrointestinal surgery (n = 17). Outcome measures included between‐group differences in medical history and medication use, and survey‐based scores for hypoglycemia, dumping syndrome, and autonomic symptoms.ResultsPBH participants were 92% female, age 53.4 ± 11.9 y, BMI 31.2 ± 5.6 kg/m2, versus RYGB non‐hypo (100% female, age 53.2 ± 10.5 y, BMI 32.2 ± 8.0 kg/m2) and controls (65% female, age 44.5 ± 14.6 y, BMI 30.8 ± 6.3 kg/m2). 87% of PBH reported level 3 hypoglycemia, with emergency visits in 28% and vehicle accidents in 8%. Reduced hypoglycemia awareness was reported by 82%; 13%–17% were classified as unaware (modified Clarke/Gold scores). Preoperative hypoglycemia symptoms and family history were reported by 26% and 18% of PBH. PBH had significantly higher survey scores for hypoglycemia, dumping syndrome, and autonomic symptoms, and higher self‐reported neuropathy, autonomic neuropathy, orthostatic hypotension, reflux esophagitis, intestinal dysmotility, and IBS (all p < 0.05 vs. RYGB non‐hypo). Gabapentin and PPI use was more frequent in PBH.ConclusionHigh rates of IBS, dumping symptoms, and orthostatic hypotension suggest disordered autonomic regulation as a potential contributor to PBH. Self‐reported preoperative symptoms and family history of hypoglycemia suggest possible preoperative differences in glucose metabolism in PBH.

ABSTRACTTo investigate the clinical features and mutational spectrum underlying hypertrophic cardiomyopathy (HCM) in São Miguel Island (Azores, Portugal), we analyzed 37 adult patients (12 sporadic, 25 familial) with positive genetic tests. Seven disease‐causing variants were identified, being two novels, in three sarcomeric genes (MYH7, TNNT2, and MYBPC3) and one non‐sarcomeric gene (ALPK3). The novel variants, classified as likely pathogenic (LP), involved large multi‐exon deletions in MYBPC3 (exons 26–32 and 28–33). These deletions were found in heterozygosity in two young males who remained clinically stable, though early onset may predict a more severe prognosis. Segregation analysis in a consanguineous family revealed two new genotypes: a digenic heterozygous for MYH7:c.1750G>C (p.Gly584Arg; P) and TNNT2:c.842A>T (p.Asn281Ile; LP) variants, and a homozygous for the TNNT2 variant. The 70‐year‐old homozygous patient remained stable and without arrhythmic events, challenging the belief that homozygous variants have a worse prognosis. This study is the first molecular and clinical analysis of HCM in the Azores.

AbstractBackgroundRheumatic diseases (RDs) include a broad group of disabling conditions with different phenotypes, from autoimmune to autoinflammatory, degenerative, metabolic or mixed manifestations. With the continuous efforts to identify therapeutic targets for new biologic drugs to treat overt clinical manifestations, research is also focusing on the discovery of new biomarkers to diagnose and manage early disease stages. In this context, we conducted a systematic review and meta‐analysis of Fetuin‐A (FtA), a glycoprotein synthesized by the liver that participates in several biological processes and has been proposed as a biomarker for several disorders, including rheumatoid arthritis.MethodsA systematic search in PubMed, Scopus and Web of Science, from inception to the 24th of August 2024, led to the identification of 13 manuscripts from 219 records; six additional studies were identified through reference hand‐search, for a total of 19 studies.ResultsThere was a significant decrease in FtA concentrations in RD patients (standardized mean difference, SMD = −.91; 95% CI −1.43 to −.39, p = .001), with no substantial contribution from any individual study nor publication bias. The effect size was significantly associated with erythrocyte sedimentation rate, various lipid fractions, geographical area of study conduction, study design and specific type of RD.ConclusionIn conclusion, our study identified significant reductions in FtA concentrations in RD patients versus healthy controls. These alterations were significantly associated with specific study and patient characteristics. Further research is required to identify the exact pathophysiological mechanisms underlying these alterations and the possible utility of measuring FtA for the diagnosis and management of RDs.

AbstractBackgroundLittle information describing the biologic behaviour and therapies for corneal lymphoma exist.ObjectivesTo characterise histologically confirmed equine corneal lymphoma considering breed, age or sex predisposition, histologic and immunologic features, therapies and outcomes.Study designRetrospective case series.MethodsA multicentre retrospective medical record review was used to identify horses that presented with corneal disease confirmed morphologically as corneal lymphoma from 2012 to 2022.ResultsMean age at diagnosis was 10.5 years. Males represented 18/26 cases. Warmblood (14) and Thoroughbred (6) breeds were most commonly represented. 25/26 had unilateral ocular involvement. No cases had evidence of multicentric lymphoma. Most eyes (77.7%) had a history of suspected immune‐mediated keratitis (IMMK) or eosinophilic keratitis. Morphological diagnosis confirming lymphoma was available for all cases. B‐cell lymphoma was diagnosed in 19/24 eyes for which immunohistochemistry was performed, with intermediate to large B‐cell lymphoma being most common. Fifteen of 27 eyes received at least one form of adjunctive therapy following keratectomy. Four eyes, which did not receive adjunctive therapy following keratectomy, experienced recurrence. No horses treated with adjunctive therapy following keratectomy experienced recurrence. Malignant transformation of IMMK to lymphoma was morphologically documented in one eye and suspected in three others based on recurrence of clinical signs. All globes were retained and visualised at the last follow‐up.Main limitationsIncomplete medical records, owner subjectivity concerning onset of disease and cases being lost to follow‐up.ConclusionsMalignant transformation of IMMK to corneal lymphoma likely occurs in horses. Lymphoma should be a differential for nonulcerative keratitis in horses. Keratectomy and histopathology may be considered in progressive or refractory cases of IMMK to rule out neoplastic disease. Recurrence of corneal lymphoma is unlikely following excision and adjunctive therapy. Cases with large corneal surface area or deep stromal involvement may have a likelihood for recurrence.
A Multiple‐Choice Exercise on Collocations: What Do Learners Actually Remember?
Authors: Li Alyssa Mengxue , Boers Frank 
Published: November 2024

ABSTRACTContemporary materials for second language (L2) learning feature exercises on collocations (i.e., word partnerships such as catch fire), many of which require learners to select correct word combinations from two or more candidates. A few studies of the effectiveness of these selected‐response exercises, which are essentially multiple‐choice exercises, have found that learners later reproduce wrong collocations that they were exposed to in the exercise. However, it is unclear if this is a side effect of the exercises or if the re‐emergence of wrong candidate responses is just accidental. The present study examines if wrong candidate responses that learners see in collocation exercises interfere with learners’ recall of the correct responses by having learners of L2 English tackle multiple‐choice items on verb‐noun collocations and verbally report two weeks later in a post‐test what they remember about them. The verbal reports revealed that the learners recalled reading and responding to most of the exercise items, but for only one‐ third of them did they also recall which candidate response had turned out to be correct according to the feedback they received. Furthermore, for close to one‐ fifth of collocations that learners said they already knew at the start of the exercise, these participants mistook a wrong candidate response for the correct one when they revisited the exercise two weeks later. The findings call for a cautious approach to the implementation of selected‐response exercises for collocation learning.
