Published: July 2021

Purpose
This paper aims to focus on studying the batch desorption of adsorbed crystal violet (CV) from date stones (Phoenix dactylifera), untreated (UDS) and treated using NaOH (TDS).

Design/methodology/approach
The process variables such as different desorbing agents, volume and concentration of the desorbing agent, contact time, dye concentration before adsorption and temperature affecting CV desorption from CV-loaded untreated date stones (CV@UDS) and treated adsorbent (CV@TDS) were optimized. The UDS and TDS were regenerated using 0.6 m HCl as eluent.

Findings
The HCl solution was an excellent eluent for the CV desorption from CV@UDS (96.45%) and CV@TDS (98.11%). The second-order model and the Langmuir model well exemplified experimental data with maximum desorption capacities were 63.29 mg g−1 for the CV@UDS and 243.90 mg g−1 for the CV@TDS. The calculated thermodynamic showed that the CV desorption was spontaneous, endothermic and physical. Good regeneration and reusability of UDS and TDS for the CV removal for four consecutive adsorption–desorption cycles.

Practical implications
This study provided a good example of reusing UDS and TDS with NaOH for fast removal of a toxic organic pollutant, CV from the wastewaters.

Originality/value
The use of UDS and TDS with NaOH for the first time for desorption study and their reusability to removing CV from their aqueous solutions.

Published: July 2021

Purpose
This study aims to provide control of liquids, especially against water-based ink on the paper and paperboard surface with natural substances, in also practical and greenway.

Design/methodology/approach
The paper surface was treated with natural rosin and its derivatives to obtain a hydrophobic effect and to improve printing properties. The oleoresin samples collected from Pinus nigra Arnold and Pinus pinaster Aiton trees in the controlled area and turpentine content removed was by hydrodistillation. The gum rosin (GR), fortified 10% with maleic anhydride (MGR) and esterified with 10% pentaerythritol (PMGR) samples solved in a simply alcohol and sprayed the base paper surface directly with a spray gun. Base paper samples were paperboard, bleached paper and test liner paper. Then, flexo printing was applied and printability properties were measured.

Findings
The treatment weights of these paper samples were 1.8 ± 0.5, 1.3 ± 0.5 and 0.7 ± 0.2 g/m2, respectively, compared to the base paper. Greater Cobb60 results were obtained from modified rosin samples than unmodified gum rosin-sized paperboards and the PMGR surface treatment reduces Cobb60 values by 20% and MGR treatment reduces 15% comparing to the base sheet. Then, the printing procedure was applied to the surface of the treated materials using a flexo printing system. As a result of the treatment better print density, chroma and print lightness value consumed a less hydrophobic agent and controlling water-based flexo ink on the base paper surface.

Originality/value
The unique aspect of this work was improving the hydrophobicity of the paper surfaces was achieved by spraying with natural rosin and derivatives.

PurposeDue to increase in operational risk, banks are facing huge losses. In order to avoid losses, banks need to manage operational risk. This study aims to analyze the impact of operational risk management (ORM) processes, which include identification, assessment, analysis, monitoring and control in the presence of corporate governance (CG) that can also contribute to effective ORM practices.Design/methodology/approachOperational risk management processes are used to manage operational risk along with CG. Primary data are collected through questionnaire from (167) operational risk managers of commercial banks. Multiple linear regressions has been run to analyze the data.FindingsResults indicate significant impact of CG and operational risk identification (ORI), monitoring and control on ORM practices in commercial banks of Pakistan.Originality/valueThe study suggests policy makers to improve the ORM framework by CG. Beside this, in order to lessen operational risk, proper identification, monitoring and control of operational risk could also contribute.
Reviving the Indian hospitality industry after the Covid-19 pandemic: the role of innovation in training
Authors: Gupta Vikas , Sahu Garima 
Published: July 2021

PurposeThis study aims to identify the innovative training programmes used by the hotel industry in India to support guests and employees during the Covid-19 pandemic. It also discusses the role of contemporary training programmes in boosting consumer confidence and enhancing their re-visit intentions.Design/methodology/approachThe study centres on 28 virtual in-depth interviews (conducted via video conferencing applications) with hotel industry stakeholders in India based on two sets of semi-structured questionnaires. The study included hotel training managers, operations staff and some hotel guests. Interviewees were selected using a non-random purposive sampling method.FindingsResults suggest that the implementation of new training programmes has significantly and positively influenced the re-visit intentions of guests. The study highlights the fact that the majority of guests prefer hotels that have stringent hygiene and sanitation protocols and where the hotel staff appeared to be more concerned about the safety of the guest during service delivery. Hotels were also found to be implementing various innovative programmes, especially Covid-19 awareness training and environmental management certificate training among other specialist programmes.Originality/valuePrior research on pandemics (such as Middle-Eastern respiratory syndrome [MERS], severe acute respiratory syndrome [SARS], Spanish flu, etc.) has been undertaken and the role of training as a response, but there is little prior work on the role of these confidence-building training programmes in the Indian context and their influence on the re-visit intentions of guests after the Covid-19 pandemic.
Just say no to postmortem drug dose calculations
Authors: Maskell Peter D. 
Published: July 2021

AbstractFor years, a number of professional groups have warned forensic and clinical toxicologists against calculating an administered dose of a drug based on postmortem blood drug concentrations. But to date, there has been limited information as to how unreliable these dose calculations may actually be. Using amitriptyline as a model drug, this study used empirically determined pharmacokinetic variables for amitriptyline from clinical studies coupled with clinical overdoses (where the individual survived), and death case studies (ascribed to amitriptyline toxicity) in which the dose of amitriptyline was known. Using these data, standard pharmacokinetic equations, and general error propagation, it was possible to estimate the accuracy of calculated doses of amitriptyline, compared with the doses that were consumed. As was expected in postmortem cases, depending on the pharmacokinetic equation used, the accuracy (mean +128% to +2347%) and precision (SD ± 383% to 3698%) were too large to allow reliable estimations of the dose of amitriptyline consumed prior to death based on postmortem blood drug concentrations. This work again reinforces that dose calculations from postmortem blood drug concentrations are unreliable.

SummaryThe pharmaceutical industry faces a growing demand and recurrent shortages in many anticancer plant drugs given their extensive use in human chemotherapy. Efficient alternative strategies of supply of these natural products such as bioproduction by microorganisms are needed to ensure stable and massive manufacturing. Here, we developed and optimized yeast cell factories efficiently converting tabersonine to vindoline, a precursor of the major anticancer alkaloids vinblastine and vincristine. First, fine‐tuning of heterologous gene copies restrained side metabolites synthesis towards vindoline production. Tabersonine to vindoline bioconversion was further enhanced through a rational medium optimization (pH, composition) and a sequential feeding strategy. Finally, a vindoline titre of 266 mg l−1 (88% yield) was reached in an optimized fed‐batch bioreactor. This precursor‐directed synthesis of vindoline thus paves the way towards future industrial bioproduction through the valorization of abundant tabersonine resources.
Changes in creatinine‐to‐cystatin C ratio over 4 years, risk of diabetes, and cardiometabolic control: The China Health and Retirement Longitudinal Study
Authors: Qiu Shanhu , Cai Xue , Yuan Yang , Xie Bo , Sun Zilin , Wu Tongzhi 
Published: July 2021

AbstractBackgroundCreatinine‐to‐cystatin C ratio has attracted substantial interest as a measure to reflect health well‐being, but no studies have assessed whether its longitudinal changes are associated with risk of diabetes. We aimed to examine their association, along with the exploration of the relationship of such changes with cardiometabolic control in middle‐aged and older adults.MethodsWe included a total of 3278 participants aged ≥45 years who provided measurements of creatinine and cystatin C at baseline and 4 years later from the China Health and Retirement Longitudinal Study. Diabetes was diagnosed based on glucose, hemoglobin A1c (HbA1c), medical history, or use of antidiabetic mediations. Odds ratio (OR) and 95% confidence interval (CI) were obtained using logistic regression analyses.ResultsAfter 4‐year follow‐up, 272 participants developed diabetes. Larger increases in creatinine‐to‐cystatin C ratio were associated with lower risk of diabetes. The multivariable‐adjusted OR for diabetes per 1 SD increase in creatinine‐to‐cystatin C ratio was 0.84 (95% CI 0.72‐0.98). Compared with participants showing decreases in creatinine‐to‐cystatin C ratio but increases in body mass index (BMI), those experiencing increases in creatinine‐to‐cystatin C ratio and decreases in BMI had the largest risk reduction (multivariable‐adjusted OR 0.52). Changes in creatinine‐to‐cystatin C ratio showed inverse correlation with blood pressure, HbA1c, lipids, and C‐reactive protein at the 4‐year follow‐up. Moreover, they also correlated inversely with changes in HbA1c and C‐reactive protein (all P ≤ 0.004).ConclusionsIncreases in creatinine‐to‐cystatin C ratio led to reduced risk of diabetes and may benefit cardiometabolic control.

Published: July 2021

AbstractVasculitis may rarely be seen in the course of myeloproliferative neoplasms (MPN). In vasculitis associated with hematological diseases, mostly small‐ and medium‐vessel involvement is expected, aortitis is very rare. It is not exactly known whether large‐vessel vasculitis associated with MPN is a paraneoplastic phenomenon or coincidental. We aimed to present an uncommon case diagnosed with chronic myeloid leukemia and Takayasu arteritis concurrently.
What Determines Effective Tax Rates? The Relative Influence of Tax and Other Factors*†
Authors: Schwab Casey M. , Stomberg Bridget , Xia Junwei 
Published: July 2021

ABSTRACTMany studies use GAAP effective tax rates (ETRs) as a proxy for tax avoidance and assume that very low (high) ETRs represent the greatest (least) tax avoidance, yet ETRs can be affected by items unrelated to tax avoidance. Despite awareness of the potential limitations of ETRs versus other factors as a measure of tax avoidance, the literature lacks consistent evidence on the extent to which ETRs capture tax avoidance. We take a step toward filling this void using income tax footnote disclosures from 2008 through 2016 to investigate how well ETRs versus other factors capture cross‐sectional differences in tax avoidance. We document that ETRs below 5% and above 40% are significantly influenced by items largely unrelated to tax avoidance, such as valuation allowances and goodwill impairments. Truncating ETRs at zero and one, controlling for standard determinants of tax avoidance, and using industry‐size‐adjusted ETRs or multiyear GAAP ETRs do not eliminate the clustering of factors largely unrelated to tax avoidance in the tails of the ETR distribution. Cash ETRs attenuate but do not eliminate this clustering. Researchers can use ETR rate reconciliation data to construct an adjusted ETR that removes the influence of factors largely unrelated to tax avoidance. Our findings inform researchers about factors largely unrelated to tax avoidance that drive significant deviations in ETRs from the statutory tax rate. This is of increasing importance as the number of studies examining the consequences of very high and very low ETRs grows.

Published: July 2021

AbstractThe production of Ribes (Rosaceae) in temperate regions in Europe, Asia and New Zealand is severely constrained by damages of Cecidophyopsis mites (Acari: Eriophyidae) and blackcurrant reversion virus (BRV) (Nepovirus, Secoviridae). The infestation of Ribes plants with Cecidophyopsis mites and BRV infection is a complex tripartite system. This paper reviews scientific progress and knowledge gaps on the Cecidophyopsis‐BRV‐Ribes complex emphasising Cecidophyopsis mites as a pest and natural vector of BRV, BRV as a pathogen, and Ribes as a host plant with horticultural significance. Cecidophyopsis species occurring on Ribes, their host range, geographic distribution and the role in BRV transmission is reviewed. Blackcurrant reversion disease symptoms and BRV hosts are analysed. Resistance of Ribes to Cecidophyopsis and BRV, and resistance breeding aspects are discussed. Discrepancies in research data, controversies and problems are highlighted, and further research is suggested to clarify some of the controversial aspects.
Career calling and team member proactivity: The roles of living out a calling and mentoring

Published: July 2021

AbstractWith the growing interest in the joint effects of individual and contextual factors in predicting team member proactivity, this paper examines why and when pursuing one's career calling can lead to team member proactivity. Drawing on the Work as a Calling Theory, we propose that “living out a calling” explains why employees' perceived career calling positively relates to team member proactivity and especially when the employee receives high levels of mentoring support. Our hypotheses are tested using a multisource and time‐lagged study design with a sample of 296 dyads of Chinese employees and their direct supervisors. We found support for the mediating role of living out a calling (Time 2) in the positive relationship between perceiving a calling (Time 1) and team member proactivity (Time 3). Mentoring (Time 2) moderated the perceiving a calling and living out a calling link such that when employees received more mentoring, the relationship was positive, whereas under lower levels of mentoring, the relationship was negative. Similarly, the indirect relationship between perceiving a calling and team member proactivity through living out a calling was positive at higher levels of mentoring, but the relationship was negative at lower levels of mentoring.
Voices of students with intellectual disabilities: Experiences of transition in “inclusive schools” in Indonesia
Authors: Andriana Elga , Evans David 
Published: July 2021

Accessible summary

This paper reports the experiences of primary school students with intellectual disabilities in Yogyakarta, Indonesia, during transitions within various contexts such as from “regular school” to “inclusive school,” from special class to regular class and from one year level to the next year level after experiencing year(s) of grade retention.

Students with intellectual disabilities together with their typically developing peers were involved as co‐researchers using drawings and photographs to research their educational and social experiences and report their views.

Educational transitions are rarely discussed or taken into account in the Indonesian context.

The views of the students with intellectual disability in this study are a significant contribution to the development of meaningful inclusive education in the Indonesian context, which at this time continues to represent exclusionary practices or divisions between “regular children” and “inclusion children.”

AbstractBackgroundWithin the emergence of inclusive education in Indonesia, transitions take on various forms impacting the educational and social lives of students. This paper reports the experiences of primary school students with intellectual disabilities during transitions in various contexts.MethodsAn initial period of research used arts‐informed methods to support the students to capture their journey in education. While the voice of students about inclusive education was captured through photographs, drawings and conversations, students were supported to undertake a personal research project.ResultsStudents shared a range of experiences and feelings in the interviews using the photographs and drawings as prompts. Some reported on being expelled from regular school as a result of failure to meet academic standards and transitioning to “inclusive school.” These “inclusive schools” moved the students from special to the regular classroom, and back, based on their academic performance. While students valued the opportunity of having more friends in the regular class, they voiced a preference for the special classroom for social interactions. Some students reported their experiences of being retained at year level for lack of progress in a rigid curriculum. Students expressed their conflicting emotions of sadness when retained, of happiness when promoted and despair at the level of learning support provided to “survive” in the higher year level. The students also provided insight into the identity of students with intellectual disabilities as impacted by transition experiences.ConclusionsTransitions, and barriers to transitions, come in varying forms, and students with disabilities contextualise and report them in different ways.

Published: July 2021

Tumour diagnosis relies on the visual examination of histological slides by pathologists through a microscope eyepiece. Digital pathology, the digitalization of histological slides at high magnification with slides scanners, has raised the opportunity to extract quantitative information due to image analysis. In the last decade, medical image analysis has made exceptional progress due to the development of artificial intelligence (AI) algorithms. AI has been successfully used in the field of medical imaging and more recently in digital pathology. The feasibility and usefulness of AI assisted pathology tasks have been demonstrated in the very last years and we can expect those developments to be applied to routine histopathology in the future. In this review, we will describe and illustrate this technique and present the most recent applications in the field of tumour histopathology.LINKED ARTICLESThis article is part of a themed issue on Molecular imaging ‐ visual themed issue.

AbstractSeasonal variation in precipitation regimes influences species composition and plant–animal interactions. Such temporal variation is especially relevant in the Brazilian Caatinga, the largest Seasonally Dry Tropical Forest in South America, where bat pollination is unusually frequent in comparison with other tropical plant communities. Here, we describe seasonal and annual variations of the interaction networks between nectarivorous bats and flower species in the Caatinga. Five species of nectar‐feeding bats interacted with 30 plant species. Nectarivorous bats showed high levels of interaction overlap, which contributed to ecological generalization (low specialization and modularity) and lack of nestedness in the interaction networks. This pattern was consistent across seasons and years. Chiropterophilous and non‐chiropterophilous plants were equally important components of the interaction network. The generalized interaction patterns found may be a necessary condition for the persistence of nectarivorous bats and their specialized plants in the environmentally harsh and variable Caatinga. The underappreciated generalized interactions of bats with plants calls for studies testing the effectiveness of bats in pollinating the plants they visit, including those not typically categorized as “bat‐flowers”.Abstract in Portuguese is available with online material.
