Authors: Zhou Qiwei , Wu Qiong , Sun Yuyuan , Cormican Kathryn 
Published: November 2024

PurposeShared leadership has received significant empirical and theoretical attention in the project management literature. However, a dearth of studies reveals how shared leadership promotes project performance. Drawing on the theory of conservation of resources, this research proposes a serial mediation model that investigates the relationship between shared leadership and project performance through team failure learning and team resilience.Design/methodology/approachA field study was conducted that surveyed 79 project teams in various industries (comprising 380 project team members and 79 project managers) using a multisource, time-lagged survey design.FindingsOur findings show that shared leadership has a positive impact on project performance. More importantly, team failure learning and team resilience play sequential mediating roles in the relationship between shared leadership and project performance.Practical implicationsThis research offers new ways for project managers to manage project performance effectively. Project managers are encouraged to recognize the benefits of shared leadership. To do this, they should facilitate team failure learning and improve team resilience, which serves to boost project performance.Originality/valueThis research provides a novel perspective on how shared leadership influences project performance. To the best of our knowledge, we are among the first to explore the serial mediating effects of team failure learning and team resilience on the relationship between shared leadership and project performance.
An analytical approach to incomplete spherical conformal contact: application on self-lubricating spherical plain bearings
Authors: Xue Yahong , Kang Dongzhuang 
Published: November 2024

Purpose
Contact pressure is a critical factor that significantly influences the wear of self-lubricating spherical plain bearings. The purpose of this paper is to address the issue of conformal contact in spherical plain bearings with a self-lubricating fabric liner, and then a universal theoretical analytical model for conformal contact between frictionless spheres is proposed.

Design/methodology/approach
This study establishes an analytical model to calculate the conformal contact in spherical plain bearings and verifies the new model by finite element analysis.

Findings
The new model proposed in this paper overcomes the limitations of elastic half-space and small-deformation assumptions. After conducting accuracy validation, it was observed that the computational error of the new model has significantly decreased in comparison to the Johnson model. For a conformal contact with a clearance of 0, the error is nearly 0.

Practical implications
The analytical model can calculate the contact pressure distribution of self-lubricating spherical plain bearings bonded with a self-lubricating layer and can be extended to the conformal contact problem of spherical contact surfaces in biomechanics and other fields.

Originality/value
The model presented here overcomes the limitations of the elastic half-space and small deformation assumptions. It accurately calculates the contact pressure distribution of self-lubricating spherical bearings. Moreover, the complex nonlinear relationship between variables such as normal force, clearance, maximum contact pressure and contact radius was investigated using this model. The model can also be extended and applied to the conformal contact problem of spherical contact surfaces in various fields, including biomechanics.

How hotel VR photography previews enhance customers’ immediate booking intention through mental imagery and perceived value
Authors: Wu Xiaohong , Lai Ivan Ka Wai , Chen Junwei 
Published: November 2024

Purpose
The purpose of this study is to examine how a hotel virtual reality photography (VRP) preview enhances customers’ immediate booking intention compared to a picture preview.

Design/methodology/approach
Data were collected using a one-factor between-subject experimental design and time-based systematic sampling. Respondents were asked to read a scenario on an iPad and assess a hotel preview (VRPs vs pictures) before answering the questionnaire.

Findings
The results show that a hotel VRP preview generates more mental imagery than a picture preview in terms of quantity, vividness, modality and valence. These four dimensions of mental imagery indirectly influence customers’ immediate booking intentions through perceived utilitarian value and hedonic value, among which modality has the greatest influence on utilitarian value and valence has the greatest influence on hedonic value. Moreover, utilitarian value has a stronger impact on customers’ immediate booking intentions than does hedonic value.

Originality/value
The results obtained in this study contribute to hospitality research by using cognitive consistency theory as the overarching framework, combining mental imagery theory, media richness theory and perceived value theory to explain the mechanism of tourists’ hotel booking decision-making from hotel previews. Comparing this study’s results with previous studies shows the difference in the effects of 360° (head-mounted) videos, VRPs and pictures on evoking mental imagery across tourism and hotel products, updating our knowledge of VR technology in tourism marketing.

Published: November 2024

Purpose
Residential Medication Management Reviews (RMMR) are a key component of safe, high-quality aged care service delivery. The RMMR is an interdisciplinary approach to medication management that relies on collaboration, communication and integration of systems. Acting as an improvement opportunity, the purpose of this paper is to present findings from a regional study, aimed at assessing the impact of RMMR on falls and hospital admissions and identifies barriers to impactful research in this area.

Design/methodology/approach
A three-year retrospective quantitative longitudinal practice audit was conducted in a regional state-managed high-care residential facility in Queensland, Australia. Data was collected pre-RMMR and six months post-RMMR.

Findings
The data collected was insufficient to achieve statistical significance or demonstrate the impact of RMMR on health outcomes. Factors impeding the research included limited ability to collect the data due to the lack of integration of information systems and limited stakeholder engagement resulting in poor recruitment. This highlights the need for improvement in RMMR processes and practices, and indeed wider research collaboration in the aged care sector.

Research limitations/implications
Thís paper acts as a call to action to improve research and interprofessional collaboration in Australian aged care.

Originality/value
The aged care industry needs high-quality research to drive practice improvement and collaborative care and service delivery. This paper advocates for improvements in the aged care sector with respect to research engagement and communication pathways between service providers. Advancement in systems integration for information sharing, recruitment of participants and stakeholder engagement will support evidence-based practice and process change.
Erythroderma in the elderly
Authors: Yamamoto Toshiyuki 
Published: November 2024

AbstractErythroderma is the end‐stage condition caused by various inflammatory diseases, presenting with widespread generalized coalesced erythema on the trunk and extremities. Erythroderma is not a disease itself, but rather is a symptom expressing erythrodermic condition, which is frequently associated with inguinal lymphadenopathy, chills, and mild fever. The clinical characteristics include sparing the folds of the trunk and extremities (deck‐chair sign), and cobblestone‐like disseminated grouping prurigo; however, the deck‐chair sign is not specific to papulo‐erythroderma (Ofuji disease). Erythroderma is induced by various causes, such as eczema, psoriasis, atopic dermatitis, drug eruption, lymphoma, lichen planus, pityriasis rubra pilaris, autoimmune bullous diseases, graft‐versus‐host disease, dermatomyositis, internal malignancy, and others. By contrast, it is not uncommon for even thorough investigations to often fail to identify any significant underlying or occult diseases. Such cases are often diagnosed as idiopathic erythroderma. In elderly cases, some regard erythroderma as late‐onset atopic dermatitis, even if the patient does not have a history of childhood atopic dermatitis, while others consider it as a distinct condition with immune responses similar to atopic dermatitis. The etiology of erythroderma is suggested to be a Th2‐dominant condition with IL‐4/IL‐13 playing a central role, suggesting that therapies targeting those Th2 molecules may result in sufficient effects. In this review, the characteristics of erythroderma in the elderly and new therapeutic approaches are discussed.
Landscape diversity, habitat connectivity, age and size determine the conservation value of limestone quarries for diverse wild bee communities
Authors: Kirsch Felix , Hass Annika , Alfert Thomas , Westphal Catrin 
Published: November 2024

Abstract

Abandoned and even active limestone quarries (excavation sites) can represent important secondary habitats for many species, including wild bees, associated with dry grasslands, which are threatened biodiversity hotspots in Europe. However, is not well understood how interactions between local habitat and landscape characteristics influence the value of limestone quarries for wild bees and how this could guide conservation schemes.

We studied how wild bee communities in limestone quarries are affected by landscape variables (connectivity to neighbouring dry grasslands, landscape diversity), local quarry characteristics (area, age, woody vegetation cover, flowering plant species) and their interactions. We surveyed bee communities during 208 transects in 19 quarries in southern Lower Saxony, Germany.

In total, we recorded 114 bee species (2360 individuals), including 35 endangered species. High flowering plant species richness positively affected bee abundance and richness. Large quarry area was important for determining the presence of endangered bee species. High levels of woody vegetation cover had a negative effect on bee abundance and richness. Bee abundance and richness can increase with quarry age, but only at sites with moderate woody vegetation cover.

We found potentially positive interactions between quarry age and landscape diversity and/or habitat connectivity to neighbouring dry grasslands. In particular, high habitat connectivity ensured stable richness of endangered species in old quarries.

Synthesis and applications. Observed negative effects of high woody vegetation cover on bee communities highlight the importance of local management to reduce shrub encroachment and reset successional processes in limestone quarries. Local management is particularly important in old quarries of great ecological value, where the adverse impact of high woody vegetation cover on wild bees appears to be most severe. Large and old quarries with high connectivity to neighbouring dry grasslands are especially valuable for endangered bee species. Therefore, landscape‐scale restoration and conservation of dry grasslands is the most promising approach to promote endangered bee species through enhanced habitat connectivity.
Detection of low‐level fentanyl concentrations in mixtures of cocaine, MDMA, methamphetamine, and caffeine via surface‐enhanced Raman spectroscopy

Published: November 2024

AbstractSurface‐enhanced Raman spectroscopy (SERS) was utilized to measure low‐level fentanyl concentrations mixed in common cutting agents, cocaine, 3,4‐methylenedioxymethamphetamine (MDMA), methamphetamine, and caffeine. Mixtures were prepared with a fentanyl concentration range of 0–339 μM. Data was initially analyzed by plotting the area of a diagnostic peak (1026 cm−1) against concentration to generate a calibration model. This method was successful with fentanyl/MDMA samples (LOD 0.04 μM) but not for the other mixtures. A chemometric approach was then employed. The data was evaluated using principal component analysis (PCA), partial least squares (PLS1) regression, and linear discriminant analysis (LDA). The LDA model was used to classify samples into one of three designated concentration ranges, low = 0–0.4 mM, medium = 0.4–14 mM, or high >14 mM, with fentanyl concentrations correctly classified with greater than 85% accuracy. This model was then validated using a series of “blind” fentanyl mixtures and these unknown samples were assigned to the correct concentration range with an accuracy >95%. The PLS1 model failed to provide accurate quantitative assignments for the samples but did provide an accurate prediction for the presence or absence of fentanyl. The combination of the two models enabled accurate quantitative assignment of fentanyl in binary mixtures. This work establishes a proof of concept, indicating a larger sample size could generate a more accurate model. It demonstrates that samples, containing variable, low concentrations of fentanyl, can be accurately quantified, using SERS.
Air DNA forensics: Novel air collection method investigations for human DNA identification
Authors: Bibbo Emily , Taylor Duncan , van Oorschot Roland A. H. , Goray Mariya 
Published: November 2024

AbstractModern techniques can generate highly discriminatory DNA profiles from minuscule biological samples, providing valuable information in criminal investigations and court proceedings. However, trace and touch DNA samples, due to their nature, often have lower success rates than other biological materials, such as blood. Further, forensically aware criminals can utilize gloves and meticulously clean the crime scene to remove DNA traces of themselves from contacted surfaces. Air sampling offers a novel approach to the collection of human DNA that has the potential to bypass some of these issues. This study reports on the results of research into the prevalence and persistence of human DNA in the air. The ability to collect human DNA from the air was investigated with the use of an AirPrep Cub Sampler ACD220 in different spaces, with and without the presence of individuals for various durations of sample collection. Results of this study demonstrate that level of occupation and sampling duration each have an influence on quantity and quality of DNA recovered from the air whereas the effects of orientation and distance of participants from the collection device as well as sequence of occupation remain unclear and require further investigation.
Single‐nucleus RNA sequencing reveals midgut cellular heterogeneity and transcriptional profiles in Bombyx mori cytoplasmic polyhedrosis virus infection

Published: November 2024

AbstractThe gut is not only used by insects as an organ for the digestion of food and absorption of nutrients but also as an important barrier against the invasion and proliferation of pathogenic microorganisms. Bombyx mori cytoplasmic polyhedrosis virus (BmCPV), an insect‐specific virus, predominantly colonizes the midgut epithelial cells of the silkworm, thereby jeopardizing its normal growth. However, there is limited knowledge of the cellular immune responses to viral infection and whether the infection is promoted or inhibited by different types of cells in the silkworm midgut. In this study, we used single‐nucleus RNA sequencing to identify representative enteroendocrine cells, enterocytes, and muscle cell types in the silkworm midgut. In addition, by analyzing the transcriptional profiles of various subpopulations in the infected and uninfected groups, we found that BmCPV infection suppresses the response of the antiviral pathways and induces the expression of BmHSP70, which plays a role in promoting BmCPV replication. However, certain immune genes in the midgut of the silkworm, such as BmLebocin3, were induced upon viral infection, and downregulation of BmLEB3 using RNA interference promoted BmCPV replication in the midgut of B. mori. These results suggest that viral immune evasion and active host resistance coexist in BmCPV‐infected silkworms. We reveal the richness of cellular diversity in the midgut of B. mori larvae by single‐nucleus RNA sequencing analysis and provide new insights into the complex interactions between the host and the virus at the single‐cell level.

Authors: Fang Yao‐Fan , Chang Shu‐Hao , Kuo Chang‐Fu , See Lai‐Chu 
Published: November 2024

AbstractObjectivesBiological disease‐modifying antirheumatic drugs have been the primary treatment option for moderate to severe rheumatoid arthritis (RA) in Taiwan since 2010. Tocilizumab is an interleukin‐6 receptor inhibitor, whereas tofacitinib is a Janus kinase inhibitor. The two medications were indicated to treat RA by direct and indirect inhibition of interleukin‐6 cytokine. We compared the safety outcomes of tocilizumab and tofacitinib in patients with RA in real‐world clinical settings, following the 7 key components of target trial emulation (TTE).MethodsThe data source was the Taiwan National Health Insurance Research Database. Patients with RA between 2010 and 2018 were eligible and assigned to either tocilizumab or tofacitinib based on their first prescription of these two medications. The index date was set as the first prescription date of either study medication. Propensity score stabilized weighting (PSSW) was used to balance the characteristics between the two medication groups. The incidences of safety outcomes were all‐cause mortality, cancer, coronary heart disease, stroke, venous thrombosis events, tuberculosis, joint replacement events, and herpes zoster infection. The intention‐to‐treat (ITT) effect was commenced from the index date until the study outcomes, independently, 3 years, withdrawal, or December 31, 2021, whichever occurred first. For the per‐protocol (PP) effect, patients were required to maintain the same medical group during the entire follow‐up period.ResultsA total of 2125 patients with RA who were prescribed tocilizumab (n = 844) or tofacitinib (n = 1281) were included in this study. The mean follow‐up duration was 2.78 years in the tocilizumab group and 2.83 years in the tofacitinib group. For ITT, the sample sizes were 721 and 1196 for the tocilizumab and tofacitinib, respectively, after PSSW. A substantially lower incidence rate of herpes zoster infection (per 100 patient‐years) was observed in the tocilizumab group (3.67) than in the tofacitinib group (7.61), with a hazard ratio of 0.48 (95%CI =0.37–0.63; p < .0001). All‐cause mortality, cancer, coronary heart disease, stroke, total hip replacement, and tuberculosis were similar between the two medication groups. For PP, the sample sizes were 619 and 1085 for the tocilizumab and tofacitinib, respectively, after PSSW. The results of the PP analysis were similar to those of the ITT analysis.ConclusionsTocilizumab and tofacitinib act along the same inflammatory pathway. A lower herpes zoster incident rate was observed in the tocilizumab group than in the tofacitinib group. The incidence rates of other safety concerns and mortality rates were comparable in both groups of patients with RA treated in real‐world settings.
