Community conservatism is widespread throughout microbial phyla and environments
Authors: Malfertheiner Lukas , Tackmann Janko , Rodrigues João F Matias , von Mering Christian 
Published: November 2024

AbstractEvolution gives rise to various long-term phenomena, includingPhylogenetic signal,which describes the tendency of related biological taxa to resemble each other in morphology and function. Related taxa tend to also live in similar ecological niches – this trend is termedNiche conservatism. Both concepts are widely used to understand crucial aspects of evolu1on and specia1on and are well-established in animals and plants. The extension of these concepts to microorganisms is however challenging and thus far only assumed. Here, we hypothesize that two closely related microbial species, if indeed similar in both their morphology and their ecological niche, should be found in samples with similar community compositions. We propose “community conservatism” to refer to this, and leverage a database with millions of samples and hundreds of thousands of pairs of microbial taxa to assess their relatedness and the similarity of the communities they occupy.Our findings reveal that community conservatism can be observed globally in all environments and phyla tested, to varying extents. Ecologically specialized taxa show a stronger community conservatism signal than generalists, and the signal can be discerned over nearly all taxonomic ranks. Analyzing community conservatism shows promise to advance our understanding of evolution, speciation, and the mechanisms governing community assembly in microorganisms. Furthermore, we propose it can be used to reintegrate ecological parameters into Operational Taxonomic Unit delimitation.

AbstractFungi of Ophiostomatales (Sordariomycetes, Ascomycota) always have a symbiotic relationship with bark beetles (Coleoptera: Scolytinae). In this study, we investigated the fungi associated withCryphalus piceaeandHylastessp in Fushun. Based on the four gene fragments of TUB, ITS, LSU, and TEF and morphological characteristics, 206 strains of Ophiostomatales were identified to be distributed in 21 taxa; these included an undescribed taxon. Here, we described it asCeratocystiopsis fushunensissp. nov. The results of this study provided valuable information on the relationship between fungi and bark beetles.

AbstractIntroductionDacron graft replacement is the standard therapy for ascending aorta aneurysm, involving the insertion of a prosthesis with lower compliance than native tissue, which can alter downstream hemodynamics and lead to adverse remodeling. Digital human twins (DHT), based on in-silico models, have the potential to predict biomarkers of adverse outcome and aid in designing optimal treatments tailored to the individual patient.ObjectiveWe propose a pipeline for deploying a digital human twin of the thoracic aorta to explore alternative solutions to traditional Dacron grafting, utilizing more compliant prostheses for reconstructing the ascending aorta.MethodsWe propose a DHT based on fluid-structure interaction (FSI) analysis of the thoracic aorta. We create 3 models of the patient, representing: i) the pre-operative baseline, ii) the post-operative with Dacron graft, and iii) a virtual post-operative using a compliant fibrous prosthesis. 3D geometry of the thoracic aorta for a patient with a congenital aneurysm, before and after the surgery, were reconstructed from magnetic resonance imaging (MRI). As inlet boundary condition (BC), we assigned a time-varying 3D velocity profile extrapolated from 4D flow MRI. For the outlet BCs, we coupled 0D Winkler models, tuned to match the flow rate measured in the descending aorta from 4D flow. The aortic wall and the prosthetic graft were modeled as hyperelastic materials using the Holzapfel-Gasser constitutive model and tuned to patients distensibility. FSI analysis was run for two cardiac cycles.ResultsResults were validated against 4D flow data. Quantitative comparison of outflows between FSI and 4D flow yielded relative squared errors of 5.28% and 0.33% for models (i) and (ii), respectively. Wall shear stress (WSS) and strain increased in both post-surgical scenarios (ii) and (iii) compared to (i), with a lower increase observed in the virtual scenario (iii) (p¡0.001). However, the difference between scenarios (iii) and (ii) remained moderate on average (e.g., 0.6 Pa for WSS).ConclusionsFSI analysis enables the deployment of reliable thoracic aorta DHTs to predict the impact of prostheses with different distensibility. Results indicate moderate yet promising benefits of more compliant fibrous devices on distal hemodynamics.Graphical AbstractHighlightsThe coupled momentum method for fluid-structure interaction analysis can be used to deploy a high fidelity digital twin of the aortaDacron graft induces an altered hemodynamic state in the descending aorta after ascending aorta correction.Electrowriting can be used to fabricate more compliant grafts that mitigate the adverse effect of Dacron in the descending aorta.The stress induced by a 2-folds more compliant (with respect to Dacron) graft is significantly lowerDespite the difference being relevant, it is moderate (1 Pa).

Published: November 2024

AbstractThe caudal part of a vertebrate embryo consists of somites, neural tube, lateral plate mesoderm derivatives and the tailbud. However, the minimal conditions and factors sufficient to induce the caudal region, particularly in humans, remain unresolved. Here, we show that BMP4 alone, when administered at appropriate dosage, is sufficient to induce the formation of an organizer for caudal induction. This organizer induces caudal cell fate specification and morphogenesis in zebrafish embryos. In 3D human pluripotent stem cells (hPSCs) aggregates, BMP4 can induce an elongated embryonic structure characterized by caudal fates. Importantly, hPSCs instructed by BMP4 are sufficient to induce a secondary caudal region when grafted into the animal pole of the zebrafish embryo. Our study thus uncovers BMP4 as the inducer in the formation of a caudal organizer in the vertebrate embryo.Significance statementWe demonstrate that BMP4 alone can induce the formation of a caudal organizer, a critical structure that guides the development of the caudal region in vertebrates. Using zebrafish embryos, embryonic explants, human pluripotent stem cell xenografts, and 3D human stem cell aggregates, we show that this organizer replicates morphogenesis and key differentiation pathways seen in natural development. Our findings uncover a novel role for BMP4 and define the minimal requirements for inducing this organizer, offering new insights into vertebrate development and potential applications in regenerative medicine.

ABSTRACTAdvances in genome engineering enable precise and customizable modifications of bacterial species. Toolsets for metabolic engineering that exhibit broad-host compatibility are particularly valued owing to their portability. Tn5transposon vectors have been widely used to establish random integrations of desired DNA sequences into bacterial genomes. However, the iteration of the procedure remains challenging because of the limited availability of selection markers. Here, we present CIFR, a mini-Tn5integration system for iterative genome engineering. The pCIFR vectors incorporateattPandattBsites flanking an antibiotic resistance marker used to select for the insertion. Subsequent removal of these antibiotic determinants is facilitated by the Bxb1 integrase, and a user-friendly counter-selection marker, both encoded in auxiliary plasmids. Hence, CIFR delivers engineered strains harboring stable DNA insertions and free of any antibiotic resistance cassette, allowing for the reusability of the tool. The system was validated inPseudomonas putida, Escherichia coli, andCupriavidus necator, underscoring its portability across diverse industrially-relevant hosts. The CIFR toolbox was calibrated through combinatorial integrations of chromoprotein genes inP. putida, generating strains displaying a diverse colorpalette. Next, we introduced a carotenoid biosynthesis pathway inP. putidain a two-step engineering process, showcasing the potential of the tool for pathway balancing. The broad utility of the toolbox expands the synthetic biology toolkit for metabolic engineering, allowing for the construction of complex phenotypes, while opening new possibilities in bacterial genetic manipulations.
Multimode squeezed state for reconfigurable quantum networks at telecommunication wavelengths
Authors: Roman-Rodriguez Victor , Fainsin David , Zanin Guilherme L. , Treps Nicolas , Diamanti Eleni , Parigi Valentina 
Published: November 2024

Continuous variable encoding of quantum information requires the deterministic generation of highly correlated quantum states of light in the form of quantum networks, which, in turn, necessitates the controlled generation of a large number of squeezed modes. In this paper, we present an experimental source of multimode squeezed states of light at telecommunication wavelengths. Generation at such wavelengths is especially important as it can enable quantum information processing, communication, and sensing beyond the laboratory scale. We use a single-pass spontaneous parametric down-conversion process in a nonlinear waveguide pumped with the second harmonic of a femtosecond laser. Our measurements reveal significant squeezing in more than 21 frequency modes, with a maximum squeezing value exceeding 2.5 dB. We demonstrate multiparty entanglement by measuring the state's covariance matrix. Finally, we show the source reconfigurability by preparing few-node cluster states and measure their nullifier squeezing level. These results pave the way for a scalable implementation of continuous variable quantum information protocols at telecommunication wavelengths, particularly for multiparty, entanglement-based quantum communications. Moreover, the source is compatible with additional pulse-by-pulse multiplexing, which can be utilized to construct the necessary three-dimensional entangled structures for quantum computing protocols.

The risk of clustering of deprivations in Spain: a tale of two crises
Authors: García-Gómez César , Pérez Ana , Prieto-Alaiz Mercedes 
Published: November 2024

Purpose
The At Risk of Poverty or Social Exclusion (AROPE) rate is a key indicator for monitoring poverty in Europe. However, it is not sensitive to the degree to which individuals face multiple deprivations simultaneously. This paper aims to fill this gap by studying the relationship between the three dimensions of the AROPE rate at the lower tail of their joint distribution in Spain in the period 2009–2022.

Design/methodology/approach
To capture how the different dimensions of poverty are related at the lower tail of their joint distribution, this paper proposes a multivariate left tail concentration function based on copulas. This function quantifies lower tail dependence at a finite scale, which, for practical purposes, is more suitable than estimating asymptotic measures, and can be represented in a 2D graph, facilitating interpretation and temporal comparisons. This function also provides information on overall dependence, as it is closely related to the Blomqvist’s beta.

Findings
There is a considerable risk of clustering of deprivations in Spain, with low positions in one poverty dimension extending to others. This risk increased after the Great Recession but did not decrease with the economic recovery that followed. The crisis linked to COVID-19 did not have a significant impact on the risk of clustering of deprivations. Lower tail dependence provides new valuable insights on the dependence structure of poverty dimensions beyond the analyses based on overall dependence.

Originality/value
This paper provides new theoretical results and a pioneering application of multivariate lower tail dependence measures in welfare economics using non-parametric methods.
Getting the deal: a qualitative inquiry into the task and developmental i-deal obtainment process
Authors: Garg Swati , Sinha Shuchi 
Published: November 2024

PurposeIdiosyncratic deals, or i-deals, are customizations that employees make to their jobs with the consent of their organization. This study investigates how employees obtain their task and developmental (T&D) i-deals by using qualitative data obtained from professionals in India.Design/methodology/approachIn-depth, qualitative interviews were conducted with 27 professionals employed in diverse services firms in India. Data was analysed using the Gioia guidelines (Gioia et al., 2013).FindingsThe findings show a four-stage i-deal obtainment process that highlights how the desire for a T&D i-deal emerges, strengthens and materializes into an actual discussion or negotiation, and the routes employees take depending upon the success or failure of the i-deal discussion.Originality/valueI-deals obtainment is a four-stage cyclical process, encompassing several factors, including attempts at credibility building by the i-dealer, assessing the availability of the i-deal within the organization and using influence tactics during the i-deal discussion. The application of social learning theory accentuates understanding of the i-deal obtainment process, particularly how employees develop and recognize the desire for an i-deal and how they progress through the four stages.

Authors: Nair Sridevi , Hawaldar Aparna , Kumar Arti 
Published: November 2024

Purpose
This study aims to examine the role of employee experience in influencing employee well-being and turnover intentions within organizations. The mediating role of well-being will also be investigated, along with an exploration of whether these relationships differ across genders, specifically in the Indian corporate context.

Design/methodology/approach
A descriptive, quantitative study was conducted using structured questionnaires to gather data from 111 employees in the Indian corporate sector. The study used a non-probability judgment sampling method. Data was analyzed through SPSS for descriptive and inferential statistics, and partial least squares was used to explore mediation and model fit.

Findings
The study found a significant impact of employee experience on well-being, as well as a negative correlation between both employee experience and turnover intention and well-being and turnover intention. Well-being was found to partially mediate the relationship between employee experience and turnover intention. Gender-based analysis revealed no significant differences in the relationships between these variables for men and women.

Originality/value
This research highlights the universal applicability of employee experience as a predictor of well-being and turnover intention, irrespective of gender. By establishing that gender does not moderate these relationships, this study provides new insights challenging traditional assumptions about gender disparities in workplace outcomes.
Did you notice us? An eye-tracking investigation of sponsorship at the US Olympic swim trials
Authors: Mondt Ali B. , Morse Alan , Evans Zachary 
Published: November 2024

PurposeThis study aimed to investigate the ecological validity of sponsorship effectiveness by examining the visual attention paid to sponsorship at a live sporting event and the subsequent impact of that attention on cognitive outcomes using eye tracking in a natural, real-world environment.Design/methodology/approachTwo logistic regression analyses (i.e. sponsor recall and sponsor recognition) were conducted to evaluate the impact of sponsorship exposure time, fixation duration and fixation frequency on viewer attention.FindingsThe preliminary investigation unveiled that longer exposure, strategic placement and brand repetition led to more frequent and extended fixations. The statistical examination demonstrated that a greater fixation frequency yielded a higher probability of explicit memory. However, the amount of time did not appear to influence viewers’ explicit memory. Further, females exhibited a higher probability of explicit memory compared to their male counterparts. Finally, age emerged as a significant determinant of explicit memory.Originality/valueThe significance of conducting eye-tracking studies within an authentic sport environment enhances ecological validity, leading to the development of practical and realistic approaches to boost consumers' explicit memory of sponsors. Further, the tangible evidence of how sponsorship information is processed can inform and modify sport marketing strategies to enhance the effectiveness of sponsorships.
Beyond a simple yes or no: using signal detection theory to measure sponsorship identification accuracy
Authors: Madrigal Robert , King Jesse 
Published: November 2024

PurposeSponsorship identification accuracy is typically assessed as the percentage of consumers answering “yes” when asked if a brand is a sponsor (hits). However, this fails to consider misattribution (answering “yes” for a non-sponsor brand; false alarms). Misattribution reflects consumer confusion and dilutes the benefits of an official sponsorship, offers an advantage to a non-sponsoring rival and reduces a brand’s return on sponsorship investment. Informed by signal-detection theory (SDT), we show how hits may be disentangled from false alarms using a measure of sensitivity called d-prime (d’). A related measure of response bias (c) is also discussed.Design/methodology/approachIn Study 1, we report the results of an experiment. In Study 2, we rely on a field study involving actual sponsors and fans.FindingsThe use of d’ and c is superior to tallying “yes” responses because they account for accurate sponsor attribution and misattribution to non-sponsor competitors.Originality/valueIn the context of sponsorship, we demonstrate how d’ and c can be easily calculated using Excel. Our research also includes an experimental study that establishes the hypothesized effects and then replicate results in a field setting.
Managerial incentives and accounting quality: the role of ownership in banking
Authors: Gupta Mayank 
Published: November 2024

PurposeThe study investigates the influence of managerial discretion over accruals on banks' financial reporting quality. Furthermore, it examines the role of ownership in shaping managerial incentives to manipulate banks’ reporting quality in a developing economy.Design/methodology/approachThe sample includes 37 Indian public- and private-sector banks from the fiscal year 2001–2022. The discretionary LLP (DLLP) is used to examine various managerial incentives and accounting quality. The models are estimated using panel fixed-effect regression and the system generalized method of moments. The results survive several sensitivity checks.FindingsThe results exhibit a low quality of financial reporting in public-sector banks, which is evident through the higher use of DLLP for income smoothing and signaling. In contrast, the low-capitalized private-sector banks employ DLLP to manage capital.Research limitations/implicationsThe study’s sample size is relatively small and focuses on a single country. Future researchers can investigate other emerging economies to better generalize the findings of this study.Practical implicationsThe study highlights the influential role of ownership in shaping managerial incentives in the banking industry. Moreover, the study is of utmost importance for governments, regulators and policymakers in devising policies that reduce agency conflicts and improve financial stability in emerging economies.Originality/valueThe study subscribes to the growing literature on the role of ownership in influencing the banks’ financial reporting quality. To the best of the author’s knowledge, this is one of the limited studies in the context of government-owned vs private-owned banks in an emerging economy.
Sustainability tweeting triumphs during the COP events: analysing environmental, social and governance (ESG) communication on twitter
Authors: ElAlfy Amr , Quigley John , Tang Leilei , Al Hariri Youssef , Weber Olaf 
Published: November 2024

Purpose
With the recent conclusion of the United Nations Conference of the Parties (COP) 28 in the United Arab Emirates, this study aims to investigate the tweeting behaviour of firms surrounding COP events. The authors analyse the environmental, social and governance (ESG) tweets from the COP 26 and COP 27 events, aiming to deepen the understanding of the complex relationships between social media communication, industry characteristics and financial performance. This timely analysis is critical for assessing how the latest global discussions on climate change are influencing corporate communication strategies on sustainability, offering fresh insights into the evolving dynamics of ESG engagement in the context of these pivotal international meetings.

Design/methodology/approach
In this study, the authors embrace a grounded theory approach to gain insights into the ESG and sustainability initiatives presented by companies on social media, with an intensified focus on climate change discourse. Leveraging advanced social media analytics, this study expands its scope by conducting a thorough examination of ESG-related tweets from Standard and Poor’s (S&P) 500 companies. In addition, the authors explore the relationships between such communication efforts and financial performance, applying an advanced cumulative abnormal returns (CARs) model. This methodological enhancement enables a more sophisticated understanding of how ESG communication on Twitter correlates with, and potentially influences, a firm’s market valuation and financial health, offering invaluable insights into the strategic importance of digital sustainability discourse.

Findings
The research findings introduce four novel distinct groups – Unengaged, Catalysts, Cautious and Shapers – based on firms’ proactive or reactive sustainability communication patterns. The results explore the potential impact of COP event locations on tweeting behaviour, proposing that conferences held in different regions, such as Asia versus Europe, may elicit varied reactions from S&P 500 firms. Despite no significant inter-industry differences in tweeting habits, the authors discover a significant link between firms’ financial metrics, specifically CARs, and their categorised communication styles. The results challenge the simplistic view that higher social media engagement leads to positive financial outcomes, suggesting instead that lower financial performance may drive firms to adopt more extreme communication patterns, possibly as a strategic move to enhance corporate legitimacy.

Originality/value
This study offers new insights into how companies use social media during significant climate change events, namely, COP events. By classifying firms according to their ESG communication approaches, the results reveal uncharted correlations between how companies communicate on social media, namely, Twitter, and the correlation to financial performance.
