Published: April 2022

PurposeIn order to determine the range of medium temperature zone of road asphalt, it is hoped that the evolution of viscoelastic characteristics of road asphalt under medium temperature state can be deeply explored.Design/methodology/approachIn this paper, the needle penetration test and temperature scanning test were designed for 90# and 70# bitumen as test materials, and the boundary of medium temperature zone of 90# and 70# bitumen was accurately determined by data analysis method. A mathematical model was established based on principal component analysis, and a comprehensive evaluation index was proposed to evaluate the evolution of temperature viscoelastic characteristics of road asphalt by means of standardization and rotational dimensionality reduction.FindingsThe test results show that the medium temperature zone of 90# asphalt is [−5 ± 1°C, 38 ± 1°C], and the medium temperature zone of 70# asphalt is [0 ± 1°C, 51 ± 1°C]. According to the viscoelastic response of road asphalt in the medium temperature zone, the medium temperature zone can be divided into three evolution stages: weak viscoelastic stage, viscoelastic equilibrium stage, strong viscoelastic weak stage. Analysis based on the intrinsic viscosity fillip target describing the various intrinsic viscoelastic index represents the viscoelastic properties of bitumen from different angles, and limitations inherent stick fillip for target put forward the integrated the inherent stick fillip mark information, as well as targeted and accurate evaluation of road asphalt temperature comprehensive evaluation indexes in the evolution of the viscoelastic properties of IM-T. Finally, the temperature data of asphalt pavement in several representative regions of China are compared with the determined medium temperature region, and it is proved that the research on the evolution of viscoelastic characteristics of asphalt pavement under the medium temperature condition has important practical significance.Originality/valueThe boundary of medium temperature zone of 90# and 70# base asphalt was determined, and the viscoelastic characteristic evolution of road asphalt under medium temperature state was studied deeply. Aiming at the limitation of intrinsic viscoelastic index, a comprehensive evaluation index IM-T which not only integrates the information of intrinsic viscoelastic index but also can accurately evaluate the evolution of temperature viscoelastic characteristics in road asphalt is proposed.

Authors: Chughtai Aamir Ali 
Published: April 2022

Purpose
The purpose of this study is to examine the impact of ethical leadership on negative feedback-seeking behavior (NFSB). In addition, it sought to investigate the mediating role of psychological safety and job involvement in this relationship.

Design/methodology/approach
The sample for this study comprised 238 primary and secondary school teachers who were selected from three private sector schools operating in Pakistan. Structural equation modeling was used to test the research hypotheses.

Findings
Results revealed that as expected, psychological safety and job involvement fully mediated the effects of ethical leadership on NFSB.

Originality/value
To the best of the author’s knowledge, this is the first study that has empirically established a connection between ethical leadership and NFSB. Furthermore, it uncovers two distinct mechanisms in the form of psychological safety and job involvement through which ethical leadership can influence NFSB.
The impact of ownership structure and corporate governance on energy intensity: evidence from Indian business groups
Authors: Jadiyappa Nemiraja , Hickman Emily , Saikia Namrata 
Published: April 2022

PurposeEnergy efficiency is critical for global sustainability (International Energy Agency, 2019). The purpose of this paper is to examine how agency conflicts arising from pyramidal ownership structures impact the energy intensity (EI) of group-affiliated Indian firms. Group-affiliated firms face unique governance challenges. For instance, parent owners (promoters) may transfer profits from one group-affiliated firm to another firm in which they have greater ownership. The authors hypothesize that such governance issues will lead to underinvestment in energy-saving projects among group firms in which promoters have a low ownership stake, resulting in their greater EI.Design/methodology/approachThe authors measure EI as the ratio of total energy expense to total sales revenue (EI) and as the industry-adjusted version of this ratio. Group-affiliated Indian firms are divided into high- and low-stake firms based on the sample’s median promoter ownership.FindingsResults support the authors’ prediction: group firms in which promoters have low ownership are more energy intensive, consistent with these firms being exposed to greater governance challenges and agency conflicts that result in operating inefficiencies and/or underinvestment in energy-saving projects.Practical implicationsGiven energy efficiency will be key in addressing climate change, this study could raise awareness among activists, motivate regulators to consider agency problems among group-affiliated firms in emerging markets and may underscore the importance of environmental-related corporate disclosures.Originality/valueTo the best of the authors’ knowledge, this study is the first to identify the significant impact that firm ownership structure and associated governance challenges have on corporate EI.
Do words matter?: Using inquiry and the politics of naming to promote critical global citizenship education
Authors: Johnson Aaron Paul , Hamblin Taylor 
Published: April 2022

Purpose US president Donald J. Trump has referred to the coronavirus disease (COVID-19) as the “Chinese” virus. Trump's choice of terms (i.e. naming) provides an illustrative entry point concerning the politics of naming and how analysis of language used within historical and political contexts can be used to engage students with global education principles.Design/methodology/approach This work aims to extend Hanvey's (1976) notion of perspective consciousness to include critical elements (e.g. Andreotti, 2014) that aim to uncover power structures that ultimately shape worldviews and manifest in communicative signs/signals (e.g. language). Utilizing Dewey's invocation of language as the “tool of tools,” the authors provide a series of three classroom-ready inquiries that serve to foster critical global citizenship education.Findings Three classroom-ready inquiries informed by the inquiry design model are presented along with resources needed to teach them.Originality/value Research has suggested the concept “global” is understood by much of the world as an instrument of US hegemony that commonly normalizes Western supremacy myths (see Andreotti, 2014; Myers, 2006). Running parallel with these concerns are research findings that suggest practitioner avoidance of global citizenship education (see Cogan and Grossman, 2009; Merryfield and Kasai, 2010; Zong, 2009). With these concerns in mind, this work provides teachers with accessible tools that promote critical notions of global citizenship education in the classroom.
“Hi! How can I help you today?”: investigating the quality of chatbots–millennials relationship within the fashion industry
Authors: Murtarelli Grazia , Collina Carolina , Romenti Stefania 
Published: April 2022

PurposeChatbots represent one of the most relevant trends within the communication settings and the management of relationships with consumers. New generations, such as millennials are favourable to interact with chatbots instead of human service assistants as they recognise the benefit linked to the technological advancements. Based on these premises, the paper intends to investigate what are the main factors affecting the quality of millennials–chatbots relationships and the new generations’ attitude and intention of using them within a specific industry such as the fashion one.Design/methodology/approachIn order to achieve the aim, an online survey based on Likert-scale items from previous research has been implemented to test developed hypotheses. Construct reliability and discriminant validity of the hypothetical research model has been tested. Additionally, a partial least square analysis technique has been used with a bootstrapping technique for evaluating the significance level of path analysis.FindingsA total of 191 responses have been collected. Most of millennials have familiarity with the concept of chatbot (52.4%). Perceived ease of use (PEOU) and perceived usefulness (PU) of chatbots positively influence the attitude towards using them by millennials. Attitude towards using chatbots positively influence the behavioural intention to use chatbots. Finally, also perceived trust and perceived risk affect the behavioural intention to use chatbots.Research limitations/implicationsThis study enriches the stream of research focused on investigating the acceptance of new technologies and their use for the development of high-quality relationships with customers. This study presents some limitations: the research model has been tested by using a convenient sample; then the study has been tailored for investigating millennials' perceptions in a specific industry; finally, the study focused on relational variables as determinants of using chatbots.Practical implicationsThis study provides professionals operating in the fashion industry with practical and managerial insights relating to the perceptions collected among a precise customer cluster represented by millennials.Originality/valueThe paper investigates millennials' perceptions about chatbots within a specific industry related to the fashion system. Additionally, the paper explores at what extent relational variables such as trust and risk could affect the quality of millennials–chatbots relationship.
The power of unbiased phenotypic screens – cellulose as a first receptor for the Schitoviridae phage S6 of Erwinia amylovora
Authors: Römling Ute 
Published: April 2022

SummaryBacteriophages, host‐dependent replicative non‐cellular entities which significantly shape the microbial genomes and consequently physiological and ecological properties of the microbial populations are exploited to restrict plant, animal and human pathogens. Unravelling of phage characteristics aids the understanding of the basic molecular mechanisms of phage infections which can subsequently lead to the development of rationalized strategies to combat microbial pathogens. In an unbiased screen to investigate the molecular basis of infectivity of the fire blight pathogen Erwinia amylovora by the lytic Schitoviridae phage S6, the biofilm extracellular matrix component cellulose has been identified as a cyclic di‐GMP dependent first receptor required for infection with the phage to possess beta‐1,4‐glucosidases to degrade the exopolysaccharide. This absolute receptor dependency allows maintenance of a phage‐microbe equilibrium with a low bacterial density.
Healthy narcissism and individuation – clinical, cultural and political manifestations
Authors: West Marcus 
Published: April 2022

AbstractThis paper explores the healthy narcissism related to self‐expression and looks at how this is frequently pathologized and split‐off, with problematic consequences for the individual and for culture. This is explored through Yeats’ poem, ‘The Second Coming’, as are other personal, cultural and clinical manifestations, with a split evident between those who advocate self‐denial and those who are ‘full of passionate intensity’ and seen as narcissistic. The paper argues that the process of individuation requires us to embrace a multiplicity of self‐states, and thus a broadening of ego‐identifications, including states of vulnerability, self‐denial, self‐centredness, murderousness and power, in contrast to the unworkable unitary identifications of previous eras, where such states were projected onto scapegoat groups in, for example, racism. The neurobiological underpinnings of the core self are outlined which, the paper argues, help us better understand and accept the broad range of narcissistic phenomena. Embracing guilt, out of care and concern as described by Loewald (1979), and thus addressing states of both passive and active blindness to the other, allows us to put a ‘human head on the lion’s body’, described in Yeats’ poem. Some clinical manifestations and dynamics are also outlined.
Individual analysis: a failure or a shared experience of social justice
Authors: Fogarty Harry Wells 
Published: April 2022

AbstractThe process of Jungian analysis is reviewed and considered as inexorably intertwined with our lives in society and with aspects of our social interactions that long for interpersonal and restorative justice. Various models are reviewed, including Fanon, Gambini, Kimbles, Levine, Saban – each with an eye toward Jung’s injunction that we must move beyond ‘knowledge’ toward ‘eating and digesting’, thereby metabolizing and shifting our way of living. Dissociated aspects of the analytic couple are discussed, both as represented by and articulating transgenerational issues, phantoms, and as presented in often neglected aspects of embodiment. Jeremy Harris’s Slave Play is offered as an amplification of ubiquitous and unacknowledged transgenerational presences in our analytic interactions. Clinical examples explore countertransference aspects that illustrate Jung’s challenge, such as an unwitting prejudice toward analysis as equalling transformation and integrating resolution, or toward analysis as leaving unexamined the presumptions of class structures and privilege. A personal dream is offered to illustrate a necessary reorientation of the analyst’s ego toward an attitude in which rebirth comes only in and through interaction with the collective. It is argued that only with such interaction, which manifests movement toward social justice, is there an efficacious analysis.

Published: April 2022

AbstractObjectiveAcute aortic syndrome (AAS) comprises a triad of life‐threatening aortic conditions that are difficult to diagnose because of their non‐specific clinical presentations. Contrast‐enhanced computed tomography aortography (CTA) has a high sensitivity and specificity for these conditions. However, under‐ and over‐investigation of patients with suspected AAS using CTA carries significant risk. The aim of the present study was to evaluate the diagnostic imaging practices of CTA use for patients presenting to an ED with suspected AAS.MethodsAll atraumatic thoracic CTAs performed on patients aged ≥15 years old with suspected AAS who presented to Auckland City Hospital between 2009 and 2019 were included. Outcomes of interest were the annual ED and population incidences of AAS, and the rate of CTAs performed.ResultsA total of 1646 CTAs were included. There were 135 (8.2%) cases of at least one AAS diagnosis and 220 (13.4%) cases where an alternative diagnosis was made. The population‐adjusted number of AAS diagnoses remained relatively stable over the study period, with a mean annual AAS incidence of 19.6 (95% confidence interval 9.9–33.7) per 100 000 patients, and 3.2 (95% confidence interval 1.6–5.4) per 100 000 population. The number of ED presentations increased during the study period, along with the population‐adjusted rate of CTAs performed, from approximately 150 per 100 000 patients (2009) to 350 per 100 000 patients (2019).ConclusionsThoracic CTA use for investigating suspected AAS in our ED has recently increased. However, the annual incidence of AAS did not increase over the same period, but was higher than reported in overseas institutions.

AbstractObjectiveChildren with acquired neutropaenia due to cancer chemotherapy are at high risk of severe infection. The present study aims to describe the prevalence and predictors of poor outcomes in children with febrile neutropaenia (FN).MethodsThis is a multicentre, prospective observational study in tertiary Australian EDs. Cancer patients with FN were included. Fever was defined as a single temperature ≥38°C, and neutropaenia was defined as an absolute neutrophil count <1000/mm3. The primary outcome was the ICU admission for organ support therapy (inotropic support, mechanical ventilation, renal replacement therapy, extracorporeal life support). Secondary outcomes were: ICU admission, ICU length of stay (LOS) ≥3 days, proven or probable bacterial infection, hospital LOS ≥7 days and 28‐day mortality. Initial vital signs, biomarkers (including lactate) and clinical sepsis scores, including Systemic Inflammatory Response Syndrome, quick Sequential Organ Failure Assessment and quick Paediatric Logistic Organ Dysfunction‐2 were evaluated as predictors of poor outcomes.ResultsBetween December 2016 and January 2018, 2124 episodes of fever in children with cancer were screened, 547 episodes in 334 children met inclusion criteria. Four episodes resulted in ICU admission for organ support therapy, nine episodes required ICU admission, ICU LOS was ≥3 days in four, hospital LOS was ≥7 days in 153 and two patients died within 28 days. Vital signs, blood tests and clinical sepsis scores, including Systemic Inflammatory Response Syndrome, quick Sequential Organ Failure Assessment and quick Paediatric Logistic Organ Dysfunction‐2, performed poorly as predictors of these outcomes (area under the receiver operating characteristic curve <0.6).ConclusionsVery few patients with FN required ICU‐level care. Vital signs, biomarkers and clinical sepsis scores for the prediction of poor outcomes are of limited utility in children with FN.

AbstractIntroductionThere is no standard for insoluble particulate matters in dialysate. We evaluated the insoluble particulate matters in online prepared substitution fluid.MethodsWe evaluated particle diameters and constituent elements of particles in online prepared substitution fluid and the final endotoxin retentive filter (ETRF).ResultsThe measurement results with particles in the online prepared substitution fluid and particles attached to the final ETRF revealed that Ca‐containing particles accounted for 11 particles and Si‐containing particles accounted for 19 particles of 30 particles detected in the online prepared substitution fluid and the final ETRF.ConclusionWe presume that insoluble particulates in online prepared substitution fluid were Ca and Mg precipitated from dialysate and Si precipitated from dialysis water. Even if two ETRFs were connected in series, these particles were formed in the final ETRF.
Population pharmacokinetics of doxorubicin: A systematic review

Published: April 2022

AbstractBecause of the high interindividual pharmacokinetic variability, several population pharmacokinetic (PopPK) models of doxorubicin (DOX) were developed to characterize factors influencing such variability. However, significant predictors for DOX pharmacokinetics identified using PopPK models varied across studies. Thus, this review aims to summarize PopPK models of DOX and its metabolites (if any) as well as significant covariates influencing DOX (and its metabolites) pharmacokinetic variability. A systematic search from PubMed, CINAHL Complete, Science Direct, and SCOPUS databases identified 503 studies. Of these, 16 studies met the inclusion criteria and were included in this review. DOX pharmacokinetics was described with two‐ or three‐compartment models. Most studies found a significant increase in DOX clearance with an increase in body surface area from the median value of 1.8 m2. Moreover, this review identified that while a 10‐year increase in patient age resulted in a decrease in DOX clearance in adults and the elderly, younger children had lower DOX clearance compared to older children. Further, low DOX exposure was observed in pregnant women, and thus dosage adjustment is required. Concerning model applicability, predictive performance assessment of these published models should be performed before implementing such models in clinical practice.

AbstractPurposeThe purpose of the study was to describe vitreoretinal surgery activity and vitreoretinal surgeons in private or public practice in metropolitan France over the year 2016 to anticipate surgical training needs.MethodsPatients aged ≥20 years who had undergone vitreoretinal surgery, alone or combined with cataract surgery were included using the French National Healthcare system database. For surgery performed by ophthalmologists carrying out ≥50 procedures during the year, the incidence per 100 000 of population ≥ 20 years of age, the number and mean age of surgeons and the number of surgeons aged >55 years were calculated.ResultsOverall, 57 947 posterior segment surgical procedures were included, 40% in the public sector and 49% in the private sector for private surgeons and/or public centres performing ≥50 procedures/year. The remaining 11% of procedures were from private surgeons and/or public centres performing <50 procedures/year. The analysis included 356 surgeons with a mean age of 41 ± 10 years (39% female) in the public sector and 47 ± 10 years (14% female) in the private sector. The majority of urgent surgery was for retinal detachment (n = 30 290 [52% of total surgical procedures]). Scheduled surgery involved surgery for macular holes and epiretinal membranes (n = 16 454 [28% of total surgical procedures]). Combined vitrectomy‐phacoemulsification surgery (n = 10 120) represented 17% of all vitreoretinal surgery. University regions with the fewest surgeons and regions with surgeons >55 years of age were identified, to anticipate the training need for new surgeons.ConclusionThis study demonstrated disparities in the geographic distribution of vitreoretinal surgery in France and identified regions that need increased training capacities to ensure a sufficient number of surgeons.
