Service robot acceptance in museums: an empirical study using the service robot acceptance model (sRAM)
Authors: Wong Amy , Wong Jimmy 
Published: February 2024

Purpose
This study aims to apply the service robot acceptance model (sRAM) to examine how attitude toward human–robot interaction (HRI) and engagement influence consumer acceptance of service robots in a frontline setting.

Design/methodology/approach
Data was collected from 255 visitors who interacted with a robotic tour guide at a city museum. The data was analyzed using smart PLS 4.0.

Findings
The findings show the positive effects of subjective norms, appearance, perceived trust and positive emotion on both attitude toward HRI and engagement. In addition, social capability impacted attitude toward HRI, whereas perceived usefulness affected engagement.

Practical implications
To deliver engaging museum experiences that bring about positive word-of-mouth and intention to visit, managers need to incorporate the sRAM dimensions in the design and deployment of service robots.

Originality/value
This research uses field data to empirically validate the sRAM in the context of service robot acceptance. It introduces engagement as a novel mediating variable, enriching current understanding of human-like qualities in HRIs.
The “problem” of Australian First Nations doctoral education: a policy analysis
Authors: Raciti Maria M. , Manathunga Catherine , Qi Jing 
Published: February 2024

Purpose
Social marketing and government policy are intertwined. Despite this, policy analysis by social marketers is rare. This paper aims to address the dearth of policy analysis in social marketing and introduce and model a methodology grounded in Indigenous knowledge and from an Indigenous standpoint. In Australia, a minuscule number of First Nations people complete doctoral degrees. The most recent, major policy review, the Australian Council of Learned Academies (ACOLA) Report, made a series of recommendations, with some drawn from countries that have successfully uplifted Indigenous doctoral candidates’ success. This paper “speaks back” to the ACOLA Report.

Design/methodology/approach
This paper subjects the ACOLA Report, implementation plans and evaluations to a detailed Indigenous Critical Discourse Analysis using Nakata’s Indigenous standpoint theory and Bacchi’s Foucauldian discourse analysis to trace why policy borrowing from other countries is challenging if other elements of the political, social and cultural landscape are fundamentally unsupportive of reforms.

Findings
This paper makes arguments about the effects produced by the way the “problem” of First Nations doctoral education has been represented in this suite of Australian policy documents and the ways in which changes could be made that would actually address the pressing need for First Nations doctoral success in Australia.

Originality/value
Conducting policy analysis benefits social marketers in many ways, helping to navigate policy complexities and advocate for meaningful policy reforms for a social cause. This paper aims to spark more social marketing policy analysis and introduces a methodology uncommon to social marketing.
Quasi-static compression and energy absorption behaviour of polymeric selective laser sintered open cell lattices under varying relative densities
Authors: K Mohan Kumar , G Arumaikkannu 
Published: February 2024

Purpose
The purpose of this paper is to compare the influence of relative density (RD) and strain rates on failure mechanism and specific energy absorption (SEA) of polyamide lattices ranging from bending to stretch-dominated structures using selective laser sintering (SLS).

Design/methodology/approach
Three bending and two stretch-dominated unit cells were selected based on the Maxwell stability criterion. Lattices were designed with three RD and fabricated by SLS technique using PA12 material. Quasi-static compression tests with three strain rates were carried out using Taguchi's L9 experiments. The lattice compressive behaviour was verified with the Gibson–Ashby analytical model.

Findings
It has been observed that RD and strain rates played a vital role in lattice compressive properties by controlling failure mechanisms, resulting in distinct post-yielding responses as fluctuating and stable hardening in the plateau region. Analysis of variance (ANOVA) displayed the significant impact of RD and emphasised dissimilar influences of strain rate that vary to cell topology. Bending-dominated lattices showed better compressive properties than stretch-dominated lattices. The interesting observation is that stretch-dominated lattices with over-stiff topology exhibited less compressive properties contrary to the Maxwell stability criterion, whereas strain rate has less influence on the SEA of face-centered and body-centered cubic unit cells with vertical and horizontal struts (FBCCXYZ).

Practical implications
This comparative study is expected to provide new prospects for designing end-user parts that undergo various impact conditions like automotive bumpers and evolving techniques like hybrid and functionally graded lattices.

Originality/value
To the best of the authors' knowledge, this is the first work that relates the strain rate with compressive properties and also highlights the lattice behaviour transformation from ductile to brittle while the increase of RD and strain rate analytically using the Gibson–Ashby analytical model.

AbstractObjectiveTo evaluate risk for adverse obstetric outcomes associated with the coronavirus disease 2019 (COVID‐19) pandemic period and with COVID‐19 diagnoses.DesignSerial cross‐sectional study.SettingA national sample of US delivery hospitalisations before (1/2016 to 2/2020) and during the first 10 months of (3/2020 to 12/2020) the COVID‐19 pandemic.PopulationAll 2016–2020 US delivery hospitalisations in the National Inpatient Sample.MethodsDelivery hospitalisations were identified and stratified into pre‐pandemic and pandemic periods and the likelihood of adverse obstetric outcomes was compared using logistic regression models with adjusted odds ratios (aOR) with 95% confidence intervals (CI) as measures of association. Risk for adverse outcomes was also analysed specifically for 2020 deliveries with a COVID‐19 diagnosis.Main Outcome MeasureAdverse maternal outcomes including respiratory complications and cardiac morbidity.ResultsOf an estimated 18.2 million deliveries, 2.9 million occurred during the pandemic. The proportion of delivery hospitalisations with a COVID‐19 diagnosis increased from 0.1% in March 2020 to 3.1% in December. Comparing the pandemic period to the pre‐pandemic period, there were higher adjusted odds of transfusion (aOR 1.12, 95% CI 1.05–1.19), a respiratory complication composite (aOR 1.37, 95% CI 1.29–1.46), cardiac severe maternal morbidity (aOR 1.30, 95% 1.20–1.39), postpartum haemorrhage (aOR 1.19, 95% CI 1.15–1.24), placental abruption/antepartum haemorrhage (OR 1.04, 95% CI 1.00–1.08), and hypertensive disorders of pregnancy (OR 1.23, 95% CI 1.21–1.26). These associations were similar to unadjusted analysis. Risk for these outcomes during the pandemic period was significantly higher in the presence of a COVID‐19 diagnosis.ConclusionsIn a national estimate of delivery hospitalisations, the odds of cardiac and respiratory outcomes were higher in 2020 compared with 2016–2019. COVID‐19 diagnoses were specifically associated with a range of serious complications.
Antithrombotic effects of Protaetia brevitarsis seulensis larvae in a rat tail thrombosis model using κ‐carrageenan
Authors: Lee Kwang Yeon , Bae In Young 
Published: February 2024

AbstractThe present study aimed to investigate the preventive role of Protaetia brevitarsis seulensis (P. brevitarsis) larvae in the κ‐carrageenan‐induced rat tail thrombosis model, in comparison with that of heparin. Thrombosis was induced in Sprague–Dawley (SD) rats by intraperitoneal injection with a dose of 30 mg/kg κ‐carrageenan after receiving oral pretreatment with P. brevitarsis larvae at doses of 300 or 900 mg/kg. The control group was only given physiological saline for 7 days without the administration of κ‐carrageenan. The results indicate that pretreatment with P. brevitarsis larvae at 300 or 900 mg/kg not only significantly reduced the average length of the thrombus but also markedly decreased the fibrinogen levels and serum P‐selectin in a dose‐dependent manner (P < 0.05). However, there were no notable effects on the blood clotting times, such as prothrombin time (PT) and activated partial thromboplastin time (aPTT). Moreover, the histological analysis of tail tissues treated with P. brevitarsis larvae supported the serum biochemical findings, thereby providing evidence of enhanced blood circulation. Based on these results, it was concluded that P. brevitarsis larvae had a positive effect on preventing thrombosis in vivo through the reduction of fibrinogen and P‐selectin levels, suggesting potential applications for thrombosis prevention.
The role of geographic market definition in analysis of grocery retailing
Authors: Wang Yanghao , Çakır Metin , Park Timothy A. 
Published: February 2024

AbstractWe examine how estimates of household food demand elasticities and store profit margins vary with alternative geographic market extents using structural models of household store choice and retailer competition. Our consumer store choice model is novel, simultaneously accounting for the heterogeneity of store choice sets, households' travel distance to stores, and their store‐specific shopping basket prices. We estimate the models using a unique combination of datasets on grocery purchases. We find that the geographic market extent is positively associated with household demand elasticity and negatively associated with store profit margins. The maximum market extent at which changes in demand elasticities become statistically insignificant varies by retailers, ranging between 10 and 16 km. These findings are robust to alternative assumptions of store competition. Our results imply that overlooking the locality of retail competition can result in overestimating the magnitudes of household demand elasticities while underestimating store profit margins, characterizing a relatively more competitive market.
Between victory and peace: Unravelling the paradox of hope in intractable conflicts

Published: February 2024

AbstractPrevious research on group‐based hope has predominantly focused on positive intergroup outcomes, such as peace and harmony. In this paper, we demonstrate that hope experienced towards group‐centric political outcomes, such as a victory in a conflict and defeating the enemy, can be detrimental to peace. In Study 1, conducted among Israeli Jews, hope for victory over the Palestinians was uniquely associated with more support for extreme war policies, whereas hope for peace generally showed the opposite associations. In Study 2, we replicated these results among Muslim Pakistanis regarding the Pakistan–India dispute. Notably, in both Studies 1 and 2, only hope for victory significantly predicted personal violent extremist intentions. In Study 3, conducted with a representative sample of Israeli Jews, we found three latent profiles of hope: victory hopers, peace hopers, and dual hopers (hoping for both peace and victory). Finally, in preregistered Study 4, we longitudinally investigated how hopes for victory and peace changed from a relatively calm period in 2021 to the Israel–Hamas War of 2023, utilizing a Bivariate Latent Change Score analysis. Increases in hope for victory during the highly intense war explained the increase in support for violence. We discuss implications, limitations, and directions for future research.
Icariin promotes osteogenic differentiation of human bone marrow mesenchymal stem cells by regulating USP47/SIRT1/Wnt/β‐catenin
Authors: Wang Hongrui , Zhang Hongyue , Zhang Yuntong , Wang Panfeng 
Published: February 2024

AbstractIcariin has been shown to promote osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs). However, the underlying molecular mechanism by which Icariin regulates osteogenic differentiation needs to be further revealed. The viability of BMSCs was assessed by cell counting kit 8 assay. BMSC osteogenic differentiation ability was evaluated by detecting alkaline phosphatase activity and performing alizarin red S staining. The protein levels of osteogenic differentiation‐related markers, sirtuin 1 (SIRT1), ubiquitin‐specific protease 47 (USP47), and Wnt/β‐catenin‐related markers were determined using western blot. SIRT1 mRNA level was measured using quantitative real‐time PCR. The regulation of USP47 on SIRT1 was confirmed by ubiquitination detection and co‐immunoprecipitation analysis. Icariin could promote BMSC osteogenic differentiation. SIRT1 expression was enhanced by Icariin, and its knockdown suppressed Icariin‐induced BMSC osteogenic differentiation. Moreover, deubiquitinating enzyme USP47 could stabilize SIRT1 protein expression. Besides, SIRT1 overexpression reversed the inhibiting effect of USP47 knockdown on BMSC osteogenic differentiation, and USP47 knockdown also restrained Icariin‐induced BMSC osteogenic differentiation. Additionally, Icariin enhanced the activity of the Wnt/β‐catenin pathway by upregulating SIRT1. Icariin facilitated BMSC osteogenic differentiation via the USP47/SIRT1/Wnt/β‐catenin pathway.

Published: February 2024

AbstractObjectiveTotal thyroidectomy (TT) carries a risk of hypoparathyroidism (hypoPT). Recently, hypoPT has been associated with higher overall mortality rates. We aimed to evaluate the frequency of hypoPT and mortality in patients undergoing TT in Denmark covering 20 years.DesignRetrospective Cohort study.Patients and measurementsUsing population‐based registries, we identified all Danish individuals who had undergone TT between January 1998 and December 2017. We included a comparison cohort by randomly selecting 10 citizens for each patient, matched on sex and birth year. HypoPT was defined as treatment with active vitamin D after 12 months postoperatively. We used cumulative incidence to calculate risks and Cox regression to compare the rate of mortality between patients and the comparison cohort. We evaluated patients in different comorbidity groups using the Charlson Comorbidity Index and by different indications for surgery.Results7912 patients underwent TT in the period. The prevalence of hypoPT in the study period was 16.6%, 12 months postoperatively. After adjusting for potential confounders the risk of death due to any causes (hazard ratio; 95% confidence intervals) following TT was significantly increased (1.34; 1.15‐1.56) for patients who developed hypoPT. However, subgroup analysis revealed mortality was only increased in malignancy cases (2.48; 1.99‐3.10) whereas mortality was not increased when surgery was due to benign indications such as goitre (0.88; 0.68‐1.15) or thyrotoxicosis (0.86; 0.57‐1.28).ConclusionsThe use of active vitamin D for hypoPT was prevalent one year after TT. Patients with hypoPT did not have an increased risk of mortality following TT unless the indication was due to malignancy.

AbstractBackgroundGuidelines recommend kidney transplant alone (KTA) in compensated cirrhosis based on a few small studies, but this is not widely performed despite its potential benefit to patients and the organ supply. Our aim was to determine the outcomes of KTA in patients with compensated cirrhosis.Study designFrom 1/2012 to 12/2021, outcomes in KTA recipients with compensated cirrhosis were retrospectively compared to patients with chronic liver disease (CLD) but no cirrhosis. Patients with compensated cirrhosis were also compared to a matched cohort (based on age, time on hemodialysis, sex, and ethnicity) of KTA recipients without CLD. The outcomes included patient survival, allograft failure, allograft rejection, serious infection, liver decompensation, and length of stay (LOS).ResultsOver 9 years, 1562 KTAs were performed, with 150 (9.6%) patients having CLD mostly due to chronic hepatitis C, and a median follow‐up of 3.5 years. 32/150 (21%) had compensated cirrhosis at the time of KTA with a mean MELD‐Na of 22 (1.5). Matched controls (n = 189) were identified. We found no differences in patient survival (p = .07), allograft failure (p = .6), allograft rejection (p = .43), rates of serious infection (p = .31), as well as LOS (p = .61) among patients with compensated cirrhosis compared to patients with CLD but no cirrhosis, but with higher rates of liver decompensation (p = .004). Similarly, compared to patients without CLD, patients with cirrhosis had similar rates of patient survival (p = .20), allograft failure (p = .27), allograft rejection (p = .62) and LOS (p = .19) but with higher rates of serious infections (p = .001).ConclusionsOur study supports the safety and efficacy of KTA in patients with compensated cirrhosis.
Using icebreaker questions to improve Chinese students' engagement in transnational education – An action research
Authors: Liang Xiaoyan 
Published: February 2024

AbstractEnhancing student engagement yields a multitude of benefits for students. It not only improves their satisfaction but also increases their motivation, enriches their learning experience, reduces their sense of isolation and ultimately enhances their academic performance. However, Chinese students in transnational education are known for being silent in the classroom. With overwhelming and consistent research findings in the pedagogical literature that participation in class discussion and asking questions are crucial activities that cultivate independent learning skills and develop the ability to apply knowledge, how to get Chinese students to speak up in class has clearly become an issue of concern to educators. Informed by the UK professional standards framework (UKPSF) and underpinned by Brookfield's four lenses model, this action research examined and confirmed the positive effect of using both personal‐related and course content‐related icebreaker questions at the beginning of the class to increase Chinese students' engagement. It also identified different effects these two types of questions might have on students' engagement and the potential concerns associated.
A systems thinking approach to capture the complexity of effective routes to teaching

Published: February 2024

AbstractSTEM teacher shortage remains a serious problem in secondary education in many European countries, despite many interventions and many research studies over the last decades. The observation that past interventions and research outcomes have not significantly contributed to reduce teacher shortage implies that places to effectively intervene in the teacher education system have not been found yet. In this article, a systems thinking approach is presented to evaluate the fundamental and structural problems of an academic teacher education system regarding STEM student entry. A thorough understanding of the systemic structure of a teacher education system is essential to identify leverage points for STEM teacher recruitment. Based on systems thinking principles and theoretical frameworks, a stepwise research framework was defined, which was tested in the Dutch academic teacher education system. First, potential factors of concern were identified based on the collection of many data such as existing public information, reports and long‐term student entry data. These potential factors of concern were subsequently investigated by student surveys and structured interviews with stakeholders from science faculties and teacher training institutes. Synthesis of the results led to the identification of three leverage points for increasing STEM student entry in teacher training, which were all found at the organizational and structural level of the academic teacher education system. The systems thinking research framework presented in this article provides a valuable framework to address persistent problems in education and enables the identification of novel and potentially more effective interventions.
Full‐scale testing of near‐neutral pH stress corrosion cracking growth behavior of a vintage X52 oil pipe

Published: February 2024

AbstractThis study presents an experimental investigation conducted on a 40‐year‐old vintage X52 oil pipe segment to assess the growth behavior of near‐neutral pH stress corrosion cracking (SCC). Six cracks were introduced on the pipe specimen, each of which was associated with a unique combination of metallurgical and environmental condition. SCC growth was evident in two base metal cracks respectively exposed to C2 and NS4. Stress intensity factors at the two cracks were evaluated using extended finite element method. Near‐neutral pH environment effects were observed to have a more pronounced effect on the stress intensity factor threshold for growth than on the growth rate. Higher stress levels and aging likely contribute to the difference in growth rates of different cracks. Electrochemical analysis suggests the corrosion‐crack propagation interplay, with a faster corrosion in the NS4 solution than that in the C2 solution consistent with the observed slower crack growth in NS4.

Published: February 2024

AbstractBackgroundTrichoscopy is a noninvasive technique based on the analysis of hair structures and the scalp, which allows for early diagnosis of different forms of alopecia.MethodsWe conducted a descriptive cross‐sectional study in the Dermatology Department of Hospital Universitario “Dr. José Eleuterio González” in Monterrey, Northeastern Mexico. We included 25 patients with a confirmed diagnosis of leprosy. Ten dermoscopic characteristics were assessed in the eyebrows of these patients. Images of the medial and distal portions of the eyebrows were included. Cohen's kappa coefficient was used for the analysis of coherence between the findings of two dermatologists.ResultsOf the 25 patients, 14 were male (56%) and 11 were female (44%), with a median age of 60.28 years (IQR: 40–87). The most common findings in the medial eyebrow included vellus hair (96%) and white‐yellowish structureless areas (84%). Furthermore, the most common features of the distal eyebrow included vellus hair (96%), white yellowish structureless areas (92%), and pinpoint white dots (92%).ConclusionsTo the best of our knowledge, this study is the first of its kind to describe trichoscopy findings in different leprosy subtypes and classify them into medial and distal eyebrow findings, which seem to be the most affected areas. Identification of these changes is easier in the distal portion of the eyebrows in every subtype of leprosy. We also discovered new trichoscopic findings in the eyebrows: perifollicular hyperpigmentation and yellow dots.
