Non-redundant inertial parameters determination for dynamic identification of branched articulated robots
Authors: Tan Chao , Zhao Huan , Ding Han 
Published: June 2022

Purpose
Branched articulated robots (BARs) are highly non-linear systems; accurate dynamic identification is critical for model-based control in high-speed and heavy-load applications. However, due to some dynamic parameters being redundant, dynamic models are singular, which increases the calculation amount and reduces the robustness of identification. This paper aims to propose a novel methodology for the dynamic analysis and redundant parameters elimination of BARs.

Design/methodology/approach
At first, the motion of a rigid body is divided into constraint-dependent and constraint-independent. The redundancy of inertial parameters is analyzed from physical constraints. Then, the redundant parameters are eliminated by mapping posterior links to their antecedents, which can be applied for re-deriving the Newton–Euler formulas. Finally, through parameter transformation, the presented dynamic model is non-singular and available for identification directly.

Findings
New formulas for redundant parameters elimination are explicit and computationally efficient. This unifies the redundant parameters elimination of prismatic and revolute joints for BARs, and it is also applicable to other types of joints containing constraints. The proposed approach is conducive to facilitating the modelling phase during the robot identification. Simulation studies are conducted to illustrate the effectiveness of the proposed redundant parameters elimination and non-singular dynamic model determination. Experimental studies are carried out to verify the result of the identification algorithm.

Originality/value
This work proposes to determine and directly identify the non-redundant dynamic model of robots, which can help to reduce the procedure of obtaining the reversible regression matrix for identification.
Sponsoring many or few sports properties? Moderated mediation effect of perceived sponsor ubiquity depending on sponsor–property fit
Authors: Kang Taeahn , Matsuoka Hirotaka 
Published: June 2022

Purpose
This study aims to examine the effect of the perceived sponsor ubiquity on sponsor favorability via perceived sponsor sincerity and the moderating effect of perceived sponsor–property fit.

Design/methodology/approach
Two studies via a questionnaire survey of spectators attending a Japanese professional basketball game were conducted, and Hayes’ PROCESS macro was used for data analyses. Study 1 (n = 134) assessed how perceived sponsor ubiquity affected sponsor favorability via perceived sponsor sincerity. Study 2 (n = 206) examined a moderated mediation model incorporating a perceived sponsor–property fit.

Findings
In Studies 1 and 2, spectators perceiving a higher degree of sponsor ubiquity reported a lower degree of sponsor sincerity compared with those perceiving a lower degree of sponsor ubiquity and less favorability toward sponsors. In Study 2, the less positive effect of highly perceived ubiquity was weakened when spectators perceived a higher degree of sponsor–property fit.

Practical implications
The findings provided sponsors with insights into effectively communicating perceived ubiquity and perceived sponsor–property fit. Hence, sponsors must be careful about their ubiquitous sponsorships, as their engagement in each property can be perceived as less distinctive among consumers.

Originality/value
To the best of the authors’ knowledge, this study is the first to highlight the mediating mechanism of perceived insincerity between perceived ubiquity and favorability toward sponsors. Furthermore, evidence that fit acted as a moderator on perceived ubiquity–outcome relationships extended previous studies mainly treating fit as a direct antecedent of sponsor response.
Dynamic and ambidextrous: international expansion of digital economy ventures from an emerging market
Authors: Buyukbalci Pinar , Dulger Meral 
Published: June 2022

Purpose
This study aims to explore the internationalization trajectory of emerging country digital economy ventures by specifically concentrating on how ambidexterity facilitates international market expansion. Further, this paper examines how these ventures develop dynamic capabilities by using their ambidextrous skills in the entrepreneurial ecosystem (EE).

Design/methodology/approach
This study adopts a multiple-case research design where data were gathered from five digital economy ventures in Turkey, serving an international array of customers.

Findings
The analyses reveal that, to a large extent, internationalization is enabled by the extensive use of ambidextrous skills in the ecosystem domain. We found evidence for practicing exploration and exploitation while interacting with several ecosystem pillars grouped as founder-related, firm-related and business context-related factors. These interactions portray how ventures sense, seize and transform resources to support their international expansion.

Originality/value
This study extends the current literature on internationalization by discussing the role of ambidexterity as a dynamic capability. The findings also demonstrate the EE as a construct to explain international entrepreneurial activity. Further, the study extends the existing literature by considering the calls for research on dynamic capabilities of international new ventures (INVs). Finally, the findings point to several implications both for practitioners and policymakers.
Audit report construction: public sector organisation perspectives within a non-financial information context
Authors: Hecimovic Angela , Martinov-Bennie Nonna 
Published: June 2022

PurposeThis study aims to explore the challenges in the construction of the audit report by a public sector organisation within a non-financial information (NFI) audit context.Design/methodology/approachThis field study primarily uses data collected from semi-structured interviews, in addition to internal and external documents. The data are framed around the generic key audit report elements including audience, scope and criteria, and draw upon insights from Power (1999, 2003a, b) into NFI assurance and Fiske's (1990) insights into communication to draw inferences on the communicative value of the audit report under study.FindingsThe findings provide insights into the challenges in determining the appropriate stakeholder audience, objective, content and format of audit reports in a complex non-financial subject matter context. Despite the organisation going to considerable lengths to understand their audiences' needs and audit objectives/criteria when constructing the audit report as the literature suggests, unintended consequences resulted and the communicative value of the audit report was still questionable.Research limitations/implicationsThe evidence was analysed from an assuror's perspective. Future research may examine in more detail the user's perceptions on the communicative value of the NFI financial audit report.Practical implicationsThe paper's insights into one organisations' challenge in developing appropriate reporting practice(s) within a “new” NFI context have practical implications for the development of emerging assurance practices of other NFI both in public and private sector.Originality/valueThis paper is one of very few studies to use in-action field study approach to comprehensively examine how audit reporting practice develops in a complex non-financial subject matter context within a public sector context.
Vehicle-type strategies for manufacturer's car sharing
Authors: Liu Zhenfeng , Wang Yujie , Feng Jian 
Published: June 2022

PurposeThis paper aims to study vehicle-type strategies for the manufacturer's car sharing by accounting for consumers' behavior and the subsidy.Design/methodology/approachThe authors develop a game model, in which a monopoly manufacturer that can produce gasoline vehicles (GVs) or energy vehicles (EVs) not only sells vehicles in the sales market, but also rents them out in the sharing market by the self-built platform. The manufacturer strategically chooses which type of vehicles based on consumers' behavior and whether the government provides the EVs’ subsidy.FindingsWhen consumers' low-carbon awareness is relatively high or the marginal cost is low, the manufacturer chooses EVs. The manufacturer chooses GVs when the low-carbon awareness and the marginal cost are low. Only when the low-carbon awareness and the subsidy are not too low, the manufacturer who originally chose GVs launches EVs. When the low-carbon awareness is high, the excessive subsidy discourages the manufacturer from entering the sharing market. If the government provides the subsidy, the manufacturer launches high-end EVs. Otherwise, the manufacturer launches low-end EVs. Moreover, the subsidy increases consumer surplus and social welfare since the high subsidy makes EVs’ sharing market demand be negative.Originality/valueThis study enriches the literature on vehicle-type strategies for the manufacturer's car sharing, owns a practical significance to guide the manufacturer's operation management in the car sharing market and provides advice on whether the government should provide EVs’ subsidy.
Commentary on “Research priorities relating to communication and swallowing for individuals with learning disabilities across the lifespan”
Authors: Backhouse Anna , Howells Sophie 
Published: June 2022

Purpose
The purpose of this paper is to provide a commentary on the article by Chadd et al. The commentary sets out the key principles of good support and considers how the Royal College of Speech and Language Therapists research priorities impact on the practice of a team of Speech and Language Therapists who support people with learning disabilities, including autistic people and those with complex needs who display behaviour described as challenging. The commentary considers how the research priorities fit within current policies and frameworks and reflects on areas that could be considered further.

Design/methodology/approach
This commentary provides a narrative account of the reflections of a team of Speech and Language Therapists on the impact that the research priorities have had on their work.

Findings
The Speech and Language Therapy (SLT) team are all keen to be involved in research but identify barriers to this relating to time within their current roles and challenges in meaningfully involving people they support. The research priorities have provided a broad framework for them to use to consider areas for research, and the focus on measuring outcomes is welcome. The research priorities largely fit within the frameworks that support current social care practice; however, they are not written in a way that is accessible for most people with a learning disability, and some do not fully reflect the social model of disability. The wider involvement of people with lived experience may have led to different research priorities identified.

Originality/value
The commentary provides an account of the impact that the research priorities have had on a team of Speech and Language Therapists working within a social care setting. It encourages readers to consider the wider context for people with learning disabilities and the role SLT plays within the social model of support for improving quality of life.
Coronavirus disease 2019 and pityriasis rosea: A review of the immunological connection

Published: June 2022

AbstractSevere acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) is characterized by the activation of a cytokine storm derived from an excess release of cytokine (interleukin [IL]‐6, interferon [IFN] I, C‐X‐C motif chemokine ligand [CXCL]10, tumor necrosis factor [TNF]‐α, macrophage inflammatory protein [MIP]1) due to an uncontrolled immune activation. There has been a fivefold increase in the number of cases of pityriasis rosea during the SARS‐CoV‐2 pandemic. Using the keywords “pityriasis” and “COVID‐19”, we carried out a PubMed search, including all articles in the English language published until November 2021. We aimed to investigate the possible connection between SARS‐CoV‐2 and pityriasis rosea (PR). Pityriasis could be considered an immunological disease due to the involvement of cytokines and chemokines. Our analysis yielded 65 articles of which 53 were not considered; the others (n = 12) concerning the association between PR and COVID‐19 were included in our study. We suggest two mechanisms underlying the involvement of the skin in viral infections: (i) viruses directly affecting the skin and/or inducing host immune response thus causing cutaneous manifestations; and (ii) viruses as a possible inducer of the reactivation of another virus. The first mechanism is probably related to a release of pro‐inflammatory cytokine and infection‐related biomarkers; in the second, several pathways could be involved in the reactivation of other latent viruses (human herpesviruses 6 and 7), such as a cytokine–cytokine receptor interaction, the Janus kinase–signal transducer and activator of transcription signaling pathway, and the IL‐17 signaling pathway. We thus believe that a cytokine storm could be directly or indirectly responsible for a cutaneous manifestation. More investigations are needed to find specific pathways involved and thus confirm our speculations.

AbstractThe chemical instability of gardenia yellow pigment (GYP) limits its utilization in the food industry. In this study, the effects of different antioxidants (0.2% of tea polyphenols, sodium phytate, potassium citrate, and ascorbic acid) and microencapsulating agents (gum Arabic, maltodextrin, inulin, and gum Arabic/maltodextrin) on the degradation of GYP under different conditions (heat, light, and ferric iron) were evaluated. Then, the characteristic properties of microcapsules coated with gum Arabic/maltodextrin, gum Arabic/maltodextrin/tea polyphenols, maltodextrin, and maltodextrin/tea polyphenols were investigated. Furthermore, food models were simulated to evaluate the GYP stability of the microcapsules. The results showed that tea polyphenols, maltodextrin, and gum Arabic/maltodextrin significantly improved the GYP stability. Moreover, the presence of GYP in microcapsules was confirmed by nuclear magnetic resonance and Fourier transform infrared spectroscopy. In addition, GYP‐MD/TP possessed high thermal stability under different cooking methods.Practical ApplicationGardenia yellow pigment (GYP) is easily degraded under light and high‐temperature conditions, which limits its applications in the food industry. This study will provide effective clues for expanding the practical applications of GYP in the natural pigment industry.
Morphometric study of the vestibuloauditory organ of the African clawed frog, Xenopus laevis

Published: June 2022

AbstractIndependent auditory end‐organs appear first in amphibians in vertebrate phylogeny. In amphibians, sound detection is carried out by the amphibian papilla, basilar papilla and macula saccule. Amphibians inhabit distinct habitats and exhibit specific behaviours and sound frequency responses, so the amphibian vestibuloauditory system is an excellent model for considering the relationships between behaviour and physiological/anatomical vestibuloauditory properties. The African clawed frog, Xenopus laevis, lives in shallow water throughout its life and is thought to use sound in a higher frequency range compared with terrestrial anurans. In this study, the size of each vestibuloauditory end‐organ and the distribution of ganglion cells in the vestibuloauditory ganglion were examined using haematoxylin and eosin staining and lectin histochemistry in Xenopus laevis. This study revealed that the size ratios among end‐organs in Xenopus are similar to those in terrestrial anurans. Large and small cells were observed in the ganglion, but their distribution patterns are different from those in general terrestrial anurans. Lycopersicon esculentum lectin stained a large number of ganglion cells. Lectin‐stained cells were found throughout the whole ganglion, but were especially abundant in the caudal part. These results suggested a unique distribution pattern of the vestibuloauditory ganglion cells in Xenopus.

Published: June 2022

AbstractWe compared the differences in testicular morphology and vascular anatomy between plateau‐type Tibetan sheep and low‐altitude Small‐tailed Han sheep to explore any adaptations of Tibetan sheep to high altitudes and hypoxia factors. Testicular artery architecture specimens of plateau‐type Tibetan sheep and lowland Small‐tailed Han sheep were used to compare the physical parameters of the testis, testicular artery architecture, arterial diameter, testicular leaflets and the characteristics of epididymal head arterioles. The results showed that the weight, major axis, minor axis, overall length, caput major axis and caput minor axis in Tibetan sheep were larger than those of Small‐tailed Han sheep; however, the caput major axis of epididymal head in Tibetan sheep was smaller than that of Small‐tailed Han sheep. Compared with Small‐tailed Han sheep, the testicular knot‐like arteries of Tibetan sheep had denser spiral distribution and more small arteries, and the diameters of centripetal arteries, knot‐like arteries, centrifugal arteries and epididymal microarterioles were also thicker. The ‘spindle’ indentation on the surface of the microarteriole of the head of the testicular leaflets and the epididymis in plateau Tibetan sheep was relatively shallow. The results showed that the physical testicular characteristics, testicular artery construction and arteriole surface structure of Tibetan sheep were adapted for the plateau environment.

AbstractBackgroundThe technical difficulty an operation creates for a surgeon is difficult to measure. Current measures are poor surrogates. In both research and teaching settings it would be valuable to be able to accurately measure this degree of difficulty. The National Aeronautics and Space Administration Task Load Index (NASA TLX) is a multi‐dimensional scale designed to obtain workload estimates relating to a task. This study aimed to evaluate the NASA TLX as an objective measure of technical difficulty of an operation.MethodsSeven surgeons performed 127 pre‐defined operations (minimally invasive right hemicolectomy & re‐do bariatric surgery) and recorded a NASA TLX score after each operation. These scores were compared to numerous clinical parameters and the score was correlated with the subjective measure of whether the surgeon categorized the operation as “easy”, “moderate” or “difficult”.ResultsThe NASA TLX score was significantly correlated with operative duration, blood loss, previous abdominal surgery and the surgeons' assessment of difficulty. It did not correlate with intra‐operative or post‐operative complications, conversion to open surgery or length of stay.ConclusionsThe NASA TLX score provides a graded numerical score that that correlated significantly with the surgeon's assessment of the technical difficulty, and with operative duration, intra‐operative blood loss and previous abdominal surgery. This novel application of this tool could be employed in both research and teaching settings to score surgical difficulty and monitor a trainee's proficiency over time.

Published: June 2022

AimsA recent review identified 19 anticholinergic burden scales (ABSs) but no study has yet compared the impact of all 19 ABSs on delirium. We evaluated whether a high anticholinergic burden as classified by each ABS is associated with incident delirium.MethodWe performed a retrospective cohort study in a Swiss tertiary teaching hospital using data from 2015–2018. Included were patients aged ≥65, hospitalised ≥48 hours with no stay >24 hours in intensive care. Delirium was defined twofold: (i) ICD‐10 or CAM and (ii) ICD‐10 or CAM or DOSS. Patients' cumulative anticholinergic burden score, calculated within 24 hours after admission, was classified using a binary (<3: low, ≥3: high burden) and a categorical approach (0: no, 0.5–3: low, ≥3: high burden). Association was analysed using multivariable logistic regression.ResultsOver 25 000 patients (mean age 77.9 ± 7.6 years) were included. Of these, (i) 864 (3.3%) and (ii) 2770 (11.0%) developed delirium. Depending on the evaluated ABS, 4–63% of the patients were exposed to at least one anticholinergic drug. Out of 19 ABSs, (i) 14 and (ii) 16 showed a significant association with the outcomes. A patient with a high anticholinergic burden score had odds ratios (ORs) of 1.21 (95% confidence interval [CI]: 1.03–1.42) to 2.63 (95% CI: 2.28–3.03) for incident delirium compared to those with low or no burden.ConclusionA high anticholinergic burden within 24 hours after admission was significantly associated with incident delirium. Although prospective studies need to confirm these results, discontinuing or substituting drugs with a score of ≥3 at admission might be a targeted intervention to reduce incident delirium.
