Vertical velocity of a small sphere in a sheared granular bed
Authors: Gao Song , Ottino Julio M. , Lueptow Richard M. , Umbanhowar Paul B. 
Published: April 2024

Small particles fall through sheared beds of larger particles in settings ranging from geophysics to industry, but the study of large-to-small size ratios R, spanning the trapping threshold Rt, has been neglected. In simulations of noncohesive spheres for R<Rt, the small-sphere vertical velocity vp first increases with shear rate γ̇ as trapping time decreases, but vp then decreases as velocity fluctuations frustrate downward mobility. For R>Rt, vp is constant at low γ̇, but again decreases at high γ̇. We model these behaviors and discuss analogies with electron transport in solids.

Does digital transformation help mitigate firm innovation dilemma? A quasi-natural experiment based on the COVID-19 pandemic in China
Authors: Yang Yaru , Zhu Yingming , Du Jiazhen 
Published: April 2024

Purpose
The purpose of this paper is to investigate the impact of the COVID-19 pandemic on company innovation, specifically centering on the quantity and quality of innovation. The paper aims to provide a comprehensive understanding of whether the epidemic inhibits innovation and the role of digital transformation in mitigating this negative impact.

Design/methodology/approach
The paper uses a quasi-experimental study of the COVID-19 pandemic and constructs a differential model to analyze the relationship between the epidemic and firm innovation in three dimensions: total, quantity and quality. The paper also uses a difference-in-difference-in-differences model to test whether digital transformation of firms mitigates the negative impact of the epidemic and its mechanism of action.

Findings
The results show that COVID-19 significantly reduced the overall level of firm innovation, primarily in terms of quantity rather than quality. Furthermore, this study finds that digital transformation plays a pivotal role in mitigating the pandemic’s adverse impact on innovation. By addressing financing constraints and countering demand insufficiency, digital transformation acts as a catalyst for preserving and fostering innovation during and after the pandemic.

Originality/value
This study extends the current research on the pandemic’s impact on firm innovation at the micro level. It offers valuable insights into strategies for fostering digital transformation among Chinese enterprises in the post-pandemic era.

Published: April 2024

PurposeThe purpose of this paper is to critically examine the multinational oil companies’ (MOCs) corporate social responsibility (CSR) initiatives in Nigeria. Its special focus is to investigate the impact of the global memorandum of understanding (GMoU) on mainstreaming gender sensitivity in cash crop market supply chains in the Niger Delta region of Nigeria.Design/methodology/approachThis paper adopts an explanatory research design with a mixed method to answer the research questions and test the hypotheses. A total of 1,200 rural women respondents were sampled across the Niger Delta region.FindingsResults from the use of a combined logit model and propensity score matching indicate a significant relationship between the GMoU model and mainstreaming gender sensitivity in cash crop market supply chains in the Niger Delta.Research limitations/implicationsThis study implies that MOCs’ CSR interventions that improve women’s access to land and encourage better integration of food markets through improved roads and increased mobile networks would enable women to engage in cash crop production.Social implicationsThis implies that improving access to credit through GMoU cluster farming targeted at female farmers would improve access to finance and extension services for women in cash crop production in the Niger Delta.Originality/valueThis research contributes to the gender debate in the agricultural value chain from a CSR perspective in developing countries and is rational for demands for social projects by host communities. It concludes that businesses have an obligation to help solve problems of public concern.
Effects of socialization mechanisms on managers’ desire to have a significant impact through work: evidence from the banking sector
Authors: Frare Anderson Betti , Horz Vagner , Cruz Ana Paula Capuano da 
Published: April 2024

Purpose
This study aims to analyze the effects of socialization mechanisms (belief system and peer mentoring) on managers’ job engagement and their desire to have a significant impact through work, that is, the desire to substantially improve or facilitate the lives of others by performing their work. The study also examines the moderating role of organizational identification.

Design/methodology/approach
A survey was conducted with middle and lower-level managers at one of the largest banks in Brazil, the BankCo. The authors obtained a sample of 201 respondents and tested the research hypotheses with structural equation modeling. The authors also performed a complementary data analysis with fuzzy-set qualitative comparative analysis.

Findings
The results suggest that belief systems and peer mentoring directly promote job engagement and indirectly promote desire to have a significant impact to a better world through work (through full mediation of job engagement). The effects of job engagement on desire to have a significant impact through work are even greater when managers have high organizational identification. Finally, several causal combinations are sufficient for high levels of desire to have a significant impact through work.

Social implications
Beyond studies that examine how organizational mechanisms influence employee outcomes (e.g. performance), this study explores how socialization mechanisms can promote desire to have a significant impact through work. Thus, the authors demonstrate how organizational core values, mission statement and peer mentoring collaborate for managers to develop altruistic behavior, that is, directly related to other human values, such as empathy and ethics, being able to contribute to a world better.

Originality/value
This study developed and empirically tested a model that connects socialization mechanisms, job engagement, organizational identification and managers’ desire to have a significant impact through their work. Therefore, the paper provides insights into the relevance of socialization mechanisms for orchestrating managers’ proactive and altruistic behaviors.

AbstractBackgroundNasopharyngeal carcinoma (NPC) is a multifactorial malignancy associated with both genetic and environmental factors. Polymorphic deletions of the phase I and phase II genes involved in the detoxification of potential carcinogens may be a risk factor for nasopharyngeal carcinoma. In this study, we investigated the relationship between CYP2E1 (rs3813867), CYP2A6, GSTM1(rs1183423000) and GSTT1(rs1601993659) gene variations and NPC risk in North African countries with the highest incidence of NPC (Morocco, Algeria and Tunisia). and the evaluation of the potential use of these variants as potential biomarkers for NPC management.MethodsA total of 600 NPC cases and 545 controls frequency‐matched on ethnicity, sex, age and childhood household type, were recruited from three North African countries (Morocco, Algeria and Tunisia) and analysed. Genotyping of CYP2A6 and CYP2E1(rs3813867) was performed by polymerase chain reaction restriction (PCR)‐fragment length polymorphism (RFLP) analysis and the GSTM1 (rs1183423000) and GSTT1(rs1601993659) genetic variations were evaluated using the PCR technique.ResultsThe genotype distributions of CYP2E1(rs3813867), CYP2A6, GSTM1(rs1183423000) and GSTT1(rs1601993659) genotypes did not differ significantly among NPC cases and controls (p > 0.05). Furthermore, our data did not reveal any association with smoking and the studied variants, even when the samples were stratified by the duration period of smoking.ConclusionIn this large studied North African population, our findings suggest that the functional CYP2E1, CYP2A6, GSTM1 and GSTT1 variations did not influence NPC susceptibility.

SummaryJuvenile myelomonocytic leukaemia (JMML) is a rare myeloproliferative neoplasm requiring haematopoietic stem cell transplantation (HSCT) for potential cure. Relapse poses a significant obstacle to JMML HSCT treatment, as the lack of effective minimal residual disease (MRD)‐monitoring methods leads to delayed interventions. This retrospective study utilized the droplet digital PCR (ddPCR) technique, a highly sensitive nucleic acid detection and quantification technique, to monitor MRD in 32 JMML patients. The results demonstrated that ddPCR detected relapse manifestations earlier than traditional methods and uncovered molecular insights into JMML MRD dynamics. The findings emphasized a critical 1‐ to 3‐month window post‐HSCT for detecting molecular relapse, with 66.7% (8/12) of relapses occurring within this period. Slow MRD clearance post‐HSCT was observed, as 65% (13/20) of non‐relapse patients took over 6 months to achieve ddPCR‐MRD negativity. Furthermore, bone marrow ddPCR‐MRD levels at 1‐month post‐HSCT proved to be prognostically significant. Relapsed patients exhibited significantly elevated ddPCR‐MRD levels at this time point (p = 0.026), with a cut‐off of 0.465% effectively stratifying overall survival (p = 0.007), event‐free survival (p = 0.035) and cumulative incidence of relapse (p = 0.035). In conclusion, this study underscored ddPCR's superiority in JMML MRD monitoring post‐HSCT. It provided valuable insights into JMML MRD dynamics, offering guidance for the effective management of JMML.
“It's good for the forest and it's traditional”: Indigenous ecologies and land management at the community/NGO interface in southern Belize
Authors: Baines Kristina , Miss (Miis) Pablo 
Published: April 2024

AbstractIn 2019, the Maya Leaders Alliance unveiled “The Future We Dream,” a vision document sharing a common interest among the Mopan and Q'eqchi’ Maya people of Belize for a future in which they are committed to sustaining a reciprocal relationship with and stewardship of the land. In this context, this paper shares results from three communities bordering a forest reserve who were asked to identify important practices, which they considered “traditional” and “environmentally sustainable,” as part of a collaborative NGO project to promote indigenous forest management. Through analysis of data collected alongside Indigenous Community Promoters (ICPs), it explores how these terms were defined and deployed to discuss healthy forests and healthy communities. The paper discusses how collaborative and community‐led data collection addresses both the need to decolonize sustainability discourse and produce better data for better project outcomes (Maya, traditional ecological knowledge, forest management, environmental sustainability, indigenous land rights).
1079. Symphyotrichum laeve (L.) Á. Löve & D. Löve: Compositae
Authors: Hind Nicholas , Lambkin Deborah 
Published: April 2024

SummarySymphyotrichum laeve (L.) Á. Löve & D. Löve (Compositae: Astereae: Symphyotrichinae) is described and illustrated, and the species is provided with an expanded synonymy that includes type citations, known types, and supplementary comments for the presently accepted varieties. A commentary on the tribal position of Symphyotrichum, its recognition, infrageneric classification, and the placement of S. laeve within that classification, is provided. Most recently, Symphyotrichum laeve has been divided into four varieties, although it might be more appropriate to recognise just two subspecies; the appropriate synonymy is suggested by amalgamating the two pairs' synonymies. The material grown in the North American Prairie plantings at Wakehurst Place is more aptly called S. laeve var. laeve (or subsp. laeve) largely by the conspicuous diamond‐shaped apical green patch on the phyllaries, and the phyllaries markedly gradate nature. Notes are provided on cultivation and propagation, pests and diseases, and availability. Although illustrated previously, in 1830, the plate of Aster laevigatus was somewhat stylized, and the name, possibly applicable to Lamarck's, Willdenow's or Purch's concept, at best sensu auctt. A short commentary on Oliver Atkins Farwell, author of a few infraspecific names of, is provided.
1080. Coreopsis lanceolata L.: Compositae
Authors: Hind Nicholas , Lambkin Deborah , Tebbs Margaret 
Published: April 2024

SummaryCoreopsis lanceolata L. (Compositae: Heliantheae: Coreopsidinae) is described and illustrated, a full synonymy provided, and its taxonomic position discussed. The generic concepts are discussed in relation to Bidens L. and Cosmos Cav., noting that molecular studies have so far not been of much practical use. Cultivation requirements are also outlined, and the species long history in the literature, with three centuries of cultivation, is discussed. Methods of propagation, pests and diseases and the species' availability are also covered. Comments are also provided on the growth ‘phases’ of this somewhat variable species outlined in the literature. Rather than pointing to discreet infraspecific entities, they are simply considered part of the range of variation, to the extent that the species' synonymy covers all of the variation. Stemming from a recent literature assessment of plant phylogenies, the odd transfer of well‐known species, in Coreopsis L. and Cosmos, to Bidens, is critiqued. The UV‐absorption patterns reflecting the nectar guides in open capitula is discussed, noting that within the genus there are three distinct modes of distribution of the anthochlor pigments.
1082. Rudbeckia hirta L.
Authors: Hind Nicholas , Lambkin Deborah 
Published: April 2024

SummaryRudbeckia hirta L. (Compositae: Heliantheae: Rudbeckinae) is described and illustrated. Material in Wakehurst's North American Prairie planting would key out to the widespread Rudbeckia hirta L. var. pulcherrima Farw., in that it is a perennial, leafy in the upper half of the stem and with narrow‐lanceolate leaves. The issue of the rank of the currently recognized infraspecific taxa is highlighted and the cluttering of the synonymy with the recognition of minor, often horticultural variants discussed. A commonly cultivated species, this is one of several late‐season flowerers in the American Prairie at RBG, Kew at Wakehurst Place. Cultivars are commonly cultivated, offering a considerable colour variation in the ray limbs, but it appears that the true species is relatively uncommon, possibly having come in and gone out of fashion since it was first brought into cultivation. Statements of the species' distribution, habitat and ecological preferences, phenology, conservation status, and the etymology of both generic and specific epithets are given, along with an impressive array of vernacular names, reflecting its wide distribution and long cultivation. Comments are provided on the nectar, or honey, guides seen (under UV light) in Rudbeckia hirta. The guides are due to the presence of flavonol glucosides, these present only in the upper surface of the ray limbs. Historical uses of the species are noted, and phytochemical analyses have provided evidence that the anti‐inflammatory properties have a factual basis.

AbstractFebrile infection‐related epilepsy syndrome (FIRES) is a subset of new onset refractory status epilepticus (NORSE) that involves a febrile infection prior to the onset of the refractory status epilepticus. It is unclear whether FIRES and non‐FIRES NORSE are distinct conditions. Here, we compare 34 patients with FIRES to 30 patients with non‐FIRES NORSE for demographics, clinical features, neuroimaging, and outcomes. Because patients with FIRES were younger than patients with non‐FIRES NORSE (median = 28 vs. 48 years old, p = .048) and more likely cryptogenic (odds ratio = 6.89), we next ran a regression analysis using age or etiology as a covariate. Respiratory and gastrointestinal prodromes occurred more frequently in FIRES patients, but no difference was found for non‐infection‐related prodromes. Status epilepticus subtype, cerebrospinal fluid (CSF) and magnetic resonance imaging findings, and outcomes were similar. However, FIRES cases were more frequently cryptogenic; had higher CSF interleukin 6, CSF macrophage inflammatory protein‐1 alpha (MIP‐1a), and serum chemokine ligand 2 (CCL2) levels; and received more antiseizure medications and immunotherapy. After controlling for age or etiology, no differences were observed in presenting symptoms and signs or inflammatory biomarkers, suggesting that FIRES and non‐FIRES NORSE are very similar conditions.

ABSTRACTIntroductionHuman respiratory syncytial virus (RSV) is one of the most frequent causes of respiratory infections in children under 5 years of age, but its socioeconomic impact and burden in primary care settings is still little studied.MethodsDuring the 2022/2023 winter season, 55 pediatricians from five Italian regions participated in our community‐based study. They collected a nasal swab for RSV molecular test from 650 patients under the age of 5 with acute respiratory infections (ARIs) and performed a baseline questionnaire. The clinical and socioeconomic burden of RSV disease in primary care was evaluated by two follow‐up questionnaires completed by the parents of positive children on Days 14 and 30.ResultsRSV laboratory‐confirmed cases were 37.8% of the total recruited ARI cases, with RSV subtype B accounting for the majority (65.4%) of RSV‐positive swabs. RSV‐positive children were younger than RSV‐negative ones (median 12.5 vs. 16.5 months). The mean duration of symptoms for all children infected by RSV was 11.47 ± 6.27 days. We did not observe substantial differences in clinical severity between the two RSV subtypes, but RSV‐A positive patients required more additional pediatric examinations than RSV‐B cases. The socioeconomic impact of RSV infection was considerable, causing 53% of children to be absent from school, 46% of parents to lose working days, and 25% of families to incur extra costs.ConclusionsOur findings describe a baseline of the RSV disease burden in primary care in Italy before the introduction of upcoming immunization strategies.
Character strength traits, states, and emotional well‐being: A daily diary study
Authors: Wagner Lisa , Gander Fabian 
Published: April 2024

AbstractObjectiveDoes whole trait theory work for character strengths? This study examines the daily within‐ and between‐person variability of the manifestations of positively valued lower‐order personality characteristics, namely character strengths, their convergence with trait character strengths, and their relationships to daily measures of affect.BackgroundManifestations of personality traits vary both between‐ and within people. So far, research has focused on between‐person differences in character strengths, while within‐person differences have been neglected.MethodsGerman‐speaking participants (N = 199, 84.3% women; mean age = 26.0 years) participated in a two‐week daily diary study. They completed a baseline measure of character strength traits and daily measures of character strength states and positive and negative affect.ResultsResults suggested that character strength traits converged well with aggregated states. Further, we observed high within‐person variability in most character strengths. The trait‐state convergence and the amount of within‐person variability were predicted by whether the character strengths were rather phasic (i.e., more dependent on situational characteristics) or rather tonic (i.e., less dependent on situational characteristics). Higher within‐person variability in character strengths was related to trait levels of perspective, honesty, social intelligence, and fairness. Regarding relationships between character strengths and affect, within‐person associations were widely parallel to previously reported between‐person associations and largely independent of trait levels of character strengths.ConclusionThese findings inform research on whole trait theory and character–strengths‐based interventions.
