Nonlinear resonance in an overdamped Duffing oscillator as a model of paleoclimate oscillations
Authors: Ryd Emil , Kantz Holger 
Published: September 2024

The cause of the dominant 100-kyr cycles in Earth's paleoclimate in the last 800 000 years has since long been debated. We analyze geological temperature proxy data and retrieve an anharmonic potential from time series data. The obtained potential has bistable features but has significant differences compared to the quartic potentials derived from theoretical energy-based models. Subsequently, we demonstrate the existence of vibrational resonance (VR) and nonlinear resonance phenomena at the combination tones of the driving frequencies in a simple bistable potential without self-sustained oscillations. We find that periodic forcing by the obliquity and frequencies similar to those of the precession cycle can generate output dominated by 100-kyr cycles, thereby offering a mechanism for explaining the observations in geological data. While previous studies of VR have assumed one periodic driver to have a frequency much higher than the other, we show that for a range of amplitudes, both phenomena can occur at the orbital cycle frequencies. We find that the nonlinear resonance phenomenon is more robust to noise than VR between eccentricity and obliquity and emerges within a much larger range of amplitudes of forcing. Finally, we conclude that it is conceivable that nonlinear resonance between obliquity and precession might explain the spectral frequencies observed in the late Pleistocene.

How and when internal marketing orientation affects frontline employees’ positive word of mouth: insights from a hotel in China
Authors: Hong Zijing , Xu Angela J. , Loi Raymond , Chow Cheris W.C. 
Published: September 2024

Purpose
Drawing on the theoretical underpinnings of job crafting, this study aims to investigate how and when internal marketing orientation (IMO) promotes employees’ positive word of mouth (PWOM).

Design/methodology/approach
The two-wave, multisource data came from frontline employees and their supervisors in a hotel located in Eastern China. The hypothesized relationships were tested with Mplus with multilevel path analysis.

Findings
The results reveal that IMO encourages frontline employees to change the task, cognitive and relational boundaries of their jobs. Nevertheless, it is through relational crafting that IMO ultimately affects employees’ PWOM, especially when they work with supervisors high in felt responsibility for constructive change (FRCC).

Research limitations/implications
To the best of the authors’ knowledge, this study is one of the first studies to investigate how organizations and supervisors can work together to encourage frontline employees’ PWOM.

Practical implications
The findings carry important implications for practitioners on how to encourage frontline employees’ PWOM in the service sector.

Originality/value
First, this research adds to the limited knowledge of how organizations and supervisors can work together to promote frontline employees’ PWOM in the service sector. Second, by proposing job crafting as a key intermediary mechanism underlying IMO’s impact on employee PWOM, this research not only offers a new theoretical perspective to understand how to promote frontline employees’ PWOM but also sheds new light on the underlying mechanisms through which IMO exerts its influence on frontline employees. Third, supervisors’ FRCC as a boundary condition of IMO can help service organizations more effectively capitalize on IMO to motivate frontline employees’ engagement in job crafting and subsequent PWOM.

Authors: Bergman Bo , Klefsjö Bengt , Sörqvist Lars 
Published: September 2024

Purpose
The aim of this paper is to investigate the development of the quality movement in Sweden since the mid-20th century. The authors are convinced that a summary of the Swedish quality journey so far will offer important lessons for further quality improvements in Sweden and elsewhere.

Design/methodology/approach
The authors study how the quality movement has been included in the industrial agenda and how it has been adopted in student curricula and in research. The authors have a focus on how business leaders have learnt, adopted, adapted and innovated with respect to quality development. often in collaboration with academia.

Findings
Although the quality movement has fit well with the Swedish culture and that successful corporate leaders have successfully used the specific cultural characteristics there is still a lot to be learnt with respect to the public sector, where the ideas from the quality movement have problem to overcome institutional barriers.

Research limitations/implications
The study is limited to the Swedish context.

Practical implications
There is a serious need to revitalize the public sector by getting leaders and politicians to understand the need for systematic quality improvement.

Social implications
If future Swedish achievements with respect to healthcare and other social welfare elements are to once again become world-class, the public sector needs to be open-minded and collaborate with the industrial sector and academia to find cost-effective strategies for making quality improvements. However, the private sector must also be alert not to be overtaken by some highly active Asian countries.

Originality/value
Swedish large companies have been very successful in applying quality leadership – however, in the public sector, this has not been the case. Suggestions for improvement are made.

However, they have the potential to enhance the coach’s performance and serve as valuable assistants in intricate coaching interventions.Originality/valueThe review offered insights into the current capabilities of AI coaching chatbots, aligned with International Coaching Federation set of competencies. The review outlined the drawbacks and benefits of chatbots and their areas of application in coaching.
Increasing plant species diversity benefits soil protein accumulation in a subtropical forest
Authors: Zhu Zihong , Wanek Wolfgang , Gao Kun , Fang Yuantian , Li Dejun 
Published: September 2024

Abstract

Protein, derived from plant and microbial residues, constitutes a significant portion of soil nitrogen or organic carbon pool and plays a crucial role in determining soil nitrogen and carbon sequestration. Though diversifying plant species has been regarded as a promising strategy for promoting soil nitrogen or organic carbon accumulation during vegetation restoration or afforestation, how increasing plant species diversity (PSD) would influence soil protein pool remains unknown.

We selected 45 plots covering a natural gradient of PSD, which was reflected by the Shannon index and varied from 0.15 to 3.57, in a subtropical karst forest. The major objective was to investigate the impact of increasing PSD on soil protein abundance, with soil protein depolymerization rate and multiple biotic and abiotic variables being measured to explore the underlying mechanism.

The relative abundance of soil protein, that is proportion in soil organic matter varied between 24.1 and 34.0% with an average of 29.2 ± 2.3% across the 45 plots. Soil protein abundance increased on average by 1.56% with each unit of PSD increase. Nevertheless, soil protease activity, protein depolymerization rate and microbial amino acid uptake rate all significantly (p < 0.05) decreased as PSD increased. The mechanism underlying the increase of soil protein abundance in response to higher PSD included three aspects, that is stimulating microbial biomass and subsequent microbial residue input to the soil, promoting mineral protection of soil protein via elevating levels of soil exchangeable calcium and magnesium, and decreasing soil protease activity and protein depolymerization due to aggravated soil microbial phosphorus limitation.

Synthesis and application: Our study suggests that increasing PSD is an efficient way to promote soil protein accumulation. Given that protein is a major component of soil nitrogen or organic carbon pool, diversifying plant species during vegetation restoration or afforestation would hence benefit soil nitrogen and organic carbon sequestration.
Developing a care bundle for children who are eating and drinking with acknowledged risk: A Delphi study with speech and language therapists
Authors: Langeroudi Heideh , Feint Georgina , Smith Christina H. 
Published: September 2024

AbstractBackgroundThere is minimal research and no formal written guidance for speech and language therapists (SLTs) managing children eating and drinking with acknowledged risks (EDAR). Many SLTs lack confidence due to the complexity of these cases medically, ethically and emotionally. Guidance is recommended to aid paediatric EDAR management.AimsTo establish consensus amongst expert paediatric SLTs regarding core components of a care bundle guiding the management of children who are EDAR.Methods & ProceduresA two‐round online modified Delphi technique was used. An expert panel of UK SLTs working across paediatric settings (education, hospital, community) were recruited using snowball sampling. Both rounds comprised 36 statements related to potential components of a care bundle, which participants rated on a 7‐point scale (strongly agree to strongly disagree), and one open‐box question. Consensus was calculated using predetermined criteria (percentage, median and interquartile range) and the final list was ranked by level of importance (mean).Outcomes & ResultsA total of 35 participants completed round 1, with 31 completing round 2 (88.6% response rate). Thirty out of 36 statements achieved high to very high consensus. The nine statements reaching very high consensus covered topics such as documentation, capacity, safeguarding and person‐centred care.Conclusion & ImplicationsThere is a high level of consensus amongst SLTs about core components for a paediatric EDAR care bundle. This study provides a useful starting point for the future development of a care bundle to manage children who are EDAR.WHAT THIS PAPER ADDSWhat is already known on the subject
There is limited research and guidance for SLTs managing children who are EDAR. In adult populations, care bundles have been introduced with positive effects (e.g., better patient outcomes, increased standardisation of care and clinician confidence) and are seen as a promising avenue for paediatrics.What this study adds to the existing knowledge
To the research team's knowledge, this is the first published Delphi study on SLT opinion around a care bundle for paediatric EDAR. There were high levels of consensus amongst UK SLTs and the results highlighted documentation, capacity, safeguarding and person‐centred care as key areas in practice. Finally, the results provide a ranked list of components UK SLTs felt are important for developing a care bundle.What are the practical and clinical implications of this work?
This study could be a useful starting point for creating a care bundle to support the management of children who are EDAR.
Engaging with parents' voices to support children with neurodiversity, anxiety, trauma, and attachment issues: Towards more inclusive practice in schools
Authors: Shaw Tricia 
Published: September 2024

AbstractThe return to school following the significant disruption to education during the COVID‐19 pandemic presents challenges for students, teachers, and parents. In the English context, education leaders have expressed serious concerns about the significantly increased levels of anxiety and school absenteeism among students of all ages, particularly those with special educational needs (SEND). This article reports on the findings of a study with 10 parents of children with neurodiversity, anxiety, trauma, and attachment difficulties. The parents' views were solicited using innovative participatory tools, such as Community Asset Mapping, Blob Trees, and Unfinished Sentences, over the course of a year. The use of these tools is particularly significant as it introduces a novel approach to gathering insights in this field. The parents proposed various ways for teachers and schools to develop more inclusive practices for children with SEND. These suggestions are organised under the categories of Children, Parents, and Processes.
Linking geopolitical risk, load capacity factor, income, labor, population, and trade on natural resources: Evidence from top oil‐producing countries
Authors: Erdogan Sinan , Kartal Mustafa Tevfik , Pata Ugur Korkut 
Published: September 2024

AbstractThe global economy has been witnessing increasing geopolitical risk (GPR) in recent years. The rise in GPR has several consequences, and the impact of this situation on natural resource rent (NR) has not yet been analyzed for the major oil‐producing countries. Given this deficiency, this study analyzes the impact of GPR, gross domestic product, the labor force (LBR), load capacity factor, population density, and trade openness on the NR for the five major oil‐producing countries (namely, Canada, China, Russia, Saudi Arabia, and the United States of America). To this end, the study analyzes data for the period 1995/Q1‐2021/Q4 by using a cross‐sectional Autoregressive Distributed Lag approach. The results demonstrate that (i) an increase in GPR and load capacity factor declines the NR; (ii) an increase in gross domestic product stimulates the NR; and (iii) a rise in population density, labor force, and trade openness has a stimulating impact on the NR. Overall, the research shows that all variables substantially impact the NR. Based on the results, various policy options are discussed, such as assessing geopolitical tensions as leverage to sustainably regulate the natural resource market and growth to prevent negative impact from managing the NR effectively for the five major oil‐producing countries.
Consensus QTL map deciphered genes and pathways regulating tolerance to post‐flowering diseases in maize

Published: September 2024

AbstractPost‐flowering diseases (PFDs), such as ear rot, stalk rot and smut, affect maize yield and quality by damaging the reproductive organs, stalks and seeds. We hypothesized that quantitative trait loci (QTL) associated with different PFDs colocalize and share similar defence mechanisms. Hence, to find a stable consensus meta‐QTL (MQTL) for single or multiple PFDs, MQTL analysis was performed. QTL conferring resistance to PFD reported in 31 independent studies were collated to develop a consensus map. As many as 49 MQTL conferring PFD resistance were projected using appropriate algorithms. Most MQTL regions encompass genes encoding a wide range of defence‐related proteins. MQTL1.1 and MQTL10.5 included QTL/genes for resistance to all PFDs, which supported our hypothesis. Candidate genes for PFDs in MQTL7.1 were associated with pathogenesis‐related 1 protein and mitogen‐activated protein kinase (MAPK) signalling. MQTL5.2 encompassed chalcone flavanone isomerase and cinnamoyl coenzyme A (CoA) reductase genes involved in flavonoid and phenylpropanoid biosynthesis, respectively. Furthermore, MQTL10.4 was found to harbour genes encoding E3 ubiquitin ligase, WRKY‐TF11, calcium‐binding domains and zinc finger motifs. Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis reiterated the role of genes within MQTL7.1 in the MAPK signalling pathway, phytohormone signal transduction and plant–pathogen interaction. Hence, we propose that these genes are potential candidates for PFD resistance. Furthermore, 75% of the genes within the MQTL showed orthology with sorghum and rice, indicating that these genes were conserved across species. The role of 27 MQTL, including the six most significant MQTL, was confirmed with reported genome‐wide association study (GWAS) results. Thus, the hotspots associated with PFDs identified in our study could be reliably used in marker‐assisted breeding for PFD resistance.
Fifty years of killing and letting die: On the limits of philosophical bioethics
Authors: Räsänen Joona , Häyry Matti 
Published: September 2024

AbstractIn 1975, The New England Journal of Medicine published James Rachels' article ‘Active and Passive Euthanasia’. The argumentative method that Rachels introduced, the Bare Difference Argument (also known as the Contrast Strategy), became one of the most widely used tools in ethical reasoning. The argument, however, fails to show active euthanasia being morally permissible. It fails because Rachels takes the intuitions from the case where letting die is morally impermissible and applies the intuitions to cases where letting die is morally permissible. While it is possible to create thought‐experiments that are more analogous to euthanasia, in this respect, than Rachels' cases, they too are disanalogous to euthanasia with some of the relevant features. Creating the perfect analogy, however, would be a mistake too. Such a case would be too analogous; people would simply be divided on what kind of moral intuitions they would have. The problem thus highlights a methodological limit in philosophical bioethics and raises questions related to the roles of philosophical ethicists in the context of assisted dying.

Published: September 2024

Background and PurposePsoriasis results from the interplay of innate and adaptive immunity in the skin. Oroxylin A (OA) has shown anti‐inflammatory effects in various disorders. This study explores oroxylin A potential in treating psoriasis, particularly its impact on type I macrophage (Mφ1) polarization.Experimental ApproachOroxylin A‐mediated therapeutic effects were evaluated using imiquimod‐induced or IL‐23‐injected psoriatic mice models, followed by proteomics assays to predict potential signalling and targeting proteins. Immunofluorescence and immunoblot assays verified that oroxylin A suppresses NF‐κB signalling in Mφ1 macrophages. Co‐immunoprecipitation and microscale thermophoresis (MST) assays further demonstrated that p62 (sequestosome 1) is the target protein for oroxylin A in macrophages. Oroxylin A‐p62‐mediated suppression of psoriasis was validated in an imiquimod‐induced p62 conditional knockout (cKO) mice model.Key ResultsOroxylin A demonstrated therapeutic efficacy in murine models induced by imiquimod or IL‐23 by attenuating cutaneous inflammation and mitigating Mφ1 polarization via NF‐κB signalling. Proteomics analysis suggested SQSTM1/p62 as a key target, confirmed to interact directly with oroxylin A. Oroxylin A disrupted the p62‐PKCζ interaction by binding to PB1 domain of p62. Its anti‐inflammatory effects were significantly reduced in macrophages from p62 cKO mice compared to the wild‐type (WT) mice in psoriasis model, supporting oroxylin A role in suppressing Mφ1 polarization through its interaction with p62.Conclusion and ImplicationsOur findings demonstrated oroxylin A suppressed psoriasiform skin inflammation in mouse models by blocking the PKCζ‐p62 interaction, subsequently inhibiting the activation of NF‐κB p65 phosphorylation in macrophages.
