AbstractSexual differentiation of the brain occurs in all major vertebrate lineages but is not well understood at a molecular and cellular level. Unlike most vertebrates, sex-changing fishes have the remarkable ability to change reproductive sex during adulthood in response to social stimuli, offering a unique opportunity to understand mechanisms by which the nervous system can initiate and coordinate sexual differentiation. This study explores sexual differentiation of the forebrain using single nucleus RNA-sequencing in the anemonefishAmphiprion ocellaris, producing the first cellular atlas of a sex-changing brain. We uncover extensive sex differences in cell type-specific gene expression, relative proportions of cells, baseline neuronal excitation, and predicted inter-neuronal communication. Additionally, we identify the cholecystokinin, galanin, and estrogen systems as central molecular axes of sexual differentiation. Supported by these findings, we propose a model of neurosexual differentiation in the conserved vertebrate social decision-making network spanning multiple subtypes of neurons and glia, including neuronal subpopulations within the preoptic area that are positioned to regulate gonadal differentiation. This work deepens our understanding of sexual differentiation in the vertebrate brain and defines a rich suite of molecular and cellular pathways that differentiate during adult sex change in anemonefish.Significance StatementThis study provides key insights into brain sex differences in sex-changing anemonefish (Amphiprion ocellaris), a species that changes sex in adulthood in response to the social environment. Using single nucleus RNA-sequencing, the study provides the first brain cellular atlas showing sex differences in two crucial reproductive areas: the preoptic area and telencephalon. The research identifies notable sex-differences in cell-type proportions and gene expression, particularly in radial glia and glutamatergic neurons that co-express the neuropeptide cholecystokinin. It also highlights differences in preoptic area neurons likely involved in gonadal regulation. This work deepens our understanding of sexual differentiation of the brain in vertebrates, especially those capable of adult sex change, and illuminates key molecular and cellular beginning and endpoints of the process.

Published: January 2024

AbstractHybridization between incipient lineages is a common feature of ecomorphological diversification. We examine these phenomena in the Pisgah clade ofDesmognathussalamanders from the southern Appalachian Mountains of the eastern United States. The group contains four to seven species exhibiting two discrete phenotypes, aquatic “shovel-nosed” and semi-aquatic “black-bellied” forms. These ecomorphologies are ancient and have apparently been transmitted repeatedly between lineages through introgression. Geographically proximate populations of both phenotypes exhibit admixture, and at least two black-bellied lineages have been produced via reticulations between shovel-nosed parentals, suggesting complex transmission dynamics. However, computational constraints currently limit our ability to reconstruct network radiations from gene-tree data. Available methods are limited to level-1 networks wherein reticulations do not share edges, and higher-level networks may be non-identifiable in many cases. We present a heuristic approach to recover information from higher-level networks across a range of potentially identifiable empirical scenarios, supported by theory and simulation. When extrinsic information indicating the location and direction of hybridization events is available, our method can yield successful estimates of non-level-1 networks, or at least a reduced possible set thereof. Phylogenomic data strongly support a single backbone topology with up to five overlapping hybrid edges. These results suggest an unusual mechanism of ecomorphological hybrid speciation, wherein a binary threshold trait causes hybrids to shift between two microhabitat niches, promoting ecological divergence between sympatric hybrids and parentals. This contrasts with other well-known systems in which hybrids exhibit intermediate, novel, or transgressive phenotypes. Finally, the genetic basis of these phenotypes is unclear and further data are needed to clarify the evolutionary basis of morphological changes with ecological consequences.
B
meson anomalies within the triplet vector boson model to the light of recent measurements from LHCb
Authors: Cabarcas J. M. , Muñoz J. H. , Quintero-Poveda Néstor , Rojas Eduardo 
Published: January 2024

The triplet vector boson (TVB) is a simplified new physics model involving massive vector bosons transforming as a weak triplet vector. Such a model has been proposed as a combined explanation of the anomalous b→sμ+μ− and b→cτν¯τ data (the so-called B meson anomalies). In this work, we carry out a revamped view of the TVB model by incorporating the most recent 2022 and 2023 LHCb measurements on the lepton-flavor universality ratios R(D(*))=BR(B→D(*)τν¯τ)/BR(B→D(*)ℓ′ν¯ℓ′), R(Λc)=BR(Λb→Λcτν¯τ)/BR(Λb→Λcμν¯μ), and RK(*)=BR(B→K(*)μ+μ−)/BR(B→K(*)e+e−). We perform a global fit to explore the allowed parameter space by the new data and all relevant low-energy flavor observables including the recent experimental progress from Belle, Belle II, and LHCb. Our results are confronted with the recent high-mass dilepton searches at the LHC. We find that for a heavy TVB mass of 1 TeV a common explanation of the B meson anomalies is possible for all data with the recent LHCb measurements on R(D(*)), consistent with LHC constraints. However, this framework is in strong tension with LHC bounds when one considers all data along with the world average values reported by the Heavy Flavor Averaging Group (, Belle, and LHCb) on R(D(*)). Future measurements will be required in order to clarify such a situation.

Life cycle analysis results for engine blisk LCA
Authors: Fricke Kilian , Bergs Thomas , Ganser Philipp , Seimann Martin 
Published: January 2024

Purpose
The aviation industry has seen consistent growth over the past few decades. To maintain its sustainability and competitiveness, it is important to have a comprehensive understanding of the environmental impacts across the entire life cycle of the industry, including materials, processes and resources; manufacturing and production; lifetime services; reuse; end-of-life; and recycling. One important component of aircraft engines, integral rotors known as Blisks, are made of high-value metallic alloys that require complex and resource-intensive manufacturing processes. The purpose of this paper is to assess the ecological and economical impacts generated through Blisk production and thereby identify significant ‘hot-spots’.

Design/methodology/approach
This paper focuses on the methodology and approach for conducting a full-scale Blisk life cycle assessment (LCA) based on ISO 14040/44. Unlike previous papers in the European Aerospace Science Network series, which focused on the first two stages of LCA, this publication delves into the “life cycle impact assessment” and “interpretation” stages, providing an overview of the life cycle inventory modeling, impact category selection and presenting preliminary LCA results for the Blisk manufacturing process chain.

Findings
The result shows that the milled titanium Blisk has a lower CO2 footprint than the milled nickel Blisk, which is less than half of the global warming potential (GWP) of the milled nickel Blisk. A main contributor to GWP arises from raw material production. However, no recycling scenarios were included in the analysis, which will be the topic of further investigations.

Originality/value
The originality of this work lies in the detailed ecological assessment of the manufacturing for complex engine components and the derivation of hot spots as well as potential improvements in terms of eco-footprint reduction throughout the products cradle-to-gate cycle. The LCA results serve as a basis for future approaches of process chain optimisation, use of “greener” materials and individual process improvements.
An LLC resonant converter with wide output range fixed frequency PWM control for PEV charging applications
Authors: Wang Dangshu , Chang Menghu , Zhao Licong , Yang Yuxuan , Guan Zhimin 
Published: January 2024

Purpose
This study aims to regarding the application of traditional pulse frequency modulation control full-bridge LLC resonant converters in wide output voltage fields such as on-board chargers, there are issues with wide frequency adjustment ranges and low conversion efficiency.

Design/methodology/approach
To address these issues, this paper proposes a fixed-frequency pulse width modulation (PWM) control strategy for a full-bridge LLC resonant converter, which adjusts the gain by adjusting the duty cycle of the switches. In the full-bridge LLC converter, the two switches of the lower bridge arm are controlled by a fixed-frequency and fixed duty cycle, with their switching frequency equal to the resonant frequency, whereas the two switches of the upper bridge arm are controlled by a fixed-frequency PWM to adjust the output voltage. The operation modes of the converter are analyzed in detail, and a mathematical model of the converter is established. The gain characteristics of the converter under the fixed-frequency PWM control strategy are deeply analyzed, and the conditions for implementing zero-voltage switching (ZVS) soft switching in the converter are also analyzed in detail. The use of fixed-frequency PWM control simplifies the design of resonant parameters, and the fixed-frequency control is conducive to the design of magnetic components.

Findings
According to the fixed-frequency PWM control strategy proposed in this paper, the correctness of the control strategy is verified through simulation and the development and testing of a 500-W experimental prototype. Test results show that the primary side switches of the converter achieve ZVS and the secondary side rectifier diodes achieve zero-current switching, effectively reducing the switching losses of the converter. In addition, the control strategy reduces the reactive circulating current of the converter, and the peak efficiency of the experimental prototype can reach 95.2%.

Originality/value
The feasibility of the fixed-frequency PWM control strategy was verified through experiments, which has significant implications for improving the efficiency of the converter and simplifying the design of resonant parameters and magnetic components in wide output voltage fields such as on-board chargers.
Climate change exposure and dividend policy: evidence from textual analysis
Authors: Ongsakul Viput , Chintrakarn Pandej , Papangkorn Suwongrat , Jiraporn Pornsit 
Published: January 2024

Purpose
Taking advantage of distinctive text-based measures of climate policy uncertainty and firm-specific exposure to climate change, this study aims to examine the impact of firm-specific vulnerability on dividend policy.

Design/methodology/approach
To mitigate endogeneity, the authors apply an instrumental-variable analysis based on climate policy uncertainty as well as use additional analysis using propensity score matching and entropy balancing.

Findings
The authors show that an increase in climate policy uncertainty exacerbates firm-specific exposure considerably. Exploiting climate policy uncertainty to generate exogenous variation in firm-specific exposure, the authors demonstrate that companies more susceptible to climate change are significantly less likely to pay dividends and those that do pay dividends pay significantly smaller dividends. For instance, a rise in firm-specific exposure by one standard deviation weakens the propensity to pay dividends by 5.11%. Climate policy uncertainty originates at the national level, beyond the control of individual firms and is thus plausibly exogenous, making endogeneity less likely.

Originality/value
To the best of the authors’ knowledge, this study is the first attempt in the literature to investigate the effect of firm-specific exposure on dividend policy using a rigorous empirical framework that is less vulnerable to endogeneity and is more likely to show a causal influence, rather than a mere correlation.
Effect of corporate social irresponsibility on organizational workplace deviant behaviour: the meditating role of moral disengagement
Authors: Abbasi Munir A. , Amran Azlan , Sahar Noor e , Lim Chia Yon 
Published: January 2024

Purpose
This study aims to investigate the effects of both internal and external corporate social irresponsibility (CSI) on organizational workplace deviant behaviours (OWDB) by using social cognitive theory. The study also explores the role of moral disengagement as a mediator in this relationship.

Design/methodology/approach
Data was collected from a sample of 321 individuals employed in the textile industry of Pakistan. The study used partial least square-structural equation modelling (PLS-SEM) to estimate the relationships within the model.

Findings
The findings indicate that both internal and external CSI have a positive impact on moral disengagement. Secondly, moral disengagement drives OWDB positively. Thirdly, moral disengagement is a significant mediator that mediates between both internal and external CSI and OWDB positively.

Practical implications
This research offers novel perspectives to organizational leaders, highlighting the significance of addressing CSI in conjunction with sustainability endeavours. It is imperative for business managers to prioritize the morality of their employees.

Originality/value
This study’s novelty lies in its confirmation of the mediating role of moral disengagement in the relationship between internal and external CSI and OWDB.
Financial technology and banking market discipline in Indonesia banking
Authors: Yudaruddin Rizky 
Published: January 2024

Purpose
This study aims to assess the effectiveness of the banking market discipline in relation to the development of Financial Technology (FinTech) startups.

Design/methodology/approach
Using panel data collected from 144 banks in Indonesia from 2004 to 2018, this study’s regression models were estimated using fixed effects with robust standard errors.

Findings
This study finds that FinTech startups disturb bank deposits. Meanwhile, market discipline exists in Indonesian banks, as indicated by depositors’ behavior with higher credit and liquidity risks. However, market discipline does not exist for bank insolvency risk, which is indicated by a significant and positive relationship with the dependent variable. Therefore, the higher the number of FinTech startups, the more effective the market discipline. Empirical findings also revealed that the joint impact between FinTech startups and bank risk is also important in explaining the difference in the effectiveness of banking market discipline.

Practical implications
This study has policy implications for banks in mitigating risk associated with market discipline and instability of financial intermediation.

Originality/value
This study offers a significant contribution to the empirical literature because it specifically explores the effectiveness of the banking market discipline by focusing on the joint impact of FinTech startups and bank risk on deposits. Furthermore, this study contributes to providing empirical evidence that links between FinTech startups and bank risk affect depositor behavior at government-owned, private, large and small, as well as nonmobile and mobile adoption banks.
Tax evasion savings versus unlawful predicate proceeds: a substance-based approach
Authors: Kemsley Deen , Kemsley Sean A. 
Published: January 2024

Purpose
This paper aims to determine whether tax evasion savings qualify as unlawful proceeds for money laundering purposes. Litigators, regulators and academics have debated the question for decades. A common argument is that tax evasion allows a bad actor to save money that the perpetrator already has on hand. It does not produce a new inflow of wealth that could properly be classified as proceeds. This paper addresses the validity of this argument by using a substance-based approach.

Design/methodology/approach
This paper applies the substance-over-form principle and two specialized judicial doctrines to the matter: the economic-substance and step-transaction doctrines.

Findings
This paper finds that in substance, tax evasion savings qualify as unlawful proceeds. The opposing argument may be valid on the surface, but it does not withstand the scrutiny of the substance-based principle and insights from the doctrines.

Practical implications
The finding of this paper implies that any courts which value substance can embrace tax evasion savings as unlawful proceeds. Government prosecutors can adopt the position with confidence that substance backs them up. National regulators can push the point. The United Nations’ Financial Action Task Force can consider the option to more explicitly recommend treating tax evasion savings as unlawful proceeds for money laundering.

Originality/value
Using a unique substance-based approach, this paper demonstrates that a dollar of tax evasion savings is substantively equivalent to a dollar of unlawful tax refund proceeds for money laundering purposes. Focusing on an unlawful tax refund overcomes many of the common concerns raised against the treatment of tax evasion savings as unlawful proceeds.
The integration of education for sustainable development into accounting education: stakeholders’ salience perspectives
Authors: Al-Hazaima Huthaifa , Low Mary , Sharma Umesh 
Published: January 2024

PurposeThis paper applies a stakeholder salience theoretical framework to facilitate the understanding of the roles salient stakeholders can have in the integration of education for sustainable development, one of the important Sustainable Development Goals (SDGs), into Jordan’s university accounting education.Design/methodology/approachWe used stakeholder salience theory to inform our study. This study adopted a qualitative research method. The study used semi-structured interviews to collect qualitative, open-ended data that explored the salient stakeholders’ thoughts, beliefs and feelings about their roles in influencing the integration of education for sustainable development into the Jordanian accounting curriculum.FindingsThe results indicate that education for sustainable development in accounting is important; however, most Jordanian salient stakeholders indicate their inability to integrate sustainable education into the accounting curriculum due to their lack of power to do so. The findings show that there is currently an inappropriate distribution of power, legitimacy and urgency amongst the salient stakeholders, who indicate that a progressive education solution is required in the critical area of education for sustainable development in accounting. This research indicates that a significant number of salient stakeholders would like the Jordanian government to provide power, legitimacy and urgency to enable accounting educators to become definite stakeholders as this will enable them to integrate sustainable education into the accounting curriculum.Research limitations/implicationsThe study is limited to Jordan only. The paper draws attention to the need for an appropriate distribution of power, legitimacy and urgency amongst salient stakeholders in Jordan.Practical implicationsThis paper provides evidence that the salient stakeholders in this emerging economy want to make changes in their education system to address climate change concerns, an important SDG, through a better education curriculum for sustainable development in Jordanian universities.Social implicationsAccounting educators should be given the power to make changes in the accounting curriculum, such as integrating education for sustainable development.Originality/valueThere is an inappropriate distribution of power, legitimacy and urgency amongst the Jordanian salient stakeholders and this imbalance hinders the integration of education for sustainable development into the accounting curriculum.
Multiple diagnoses in the context of parallel epidemics: methamphetamine, opioid use disorder and psychiatric conditions
Authors: Zande Taylor , Kopak Albert , Hoffmann Norman 
Published: January 2024

Purpose
The most recent wave of the opioid epidemic in the USA has been complicated by a sharp increase in methamphetamine use. In addition, many people classified with opioid use disorder (OUD) and methamphetamine use disorder (MUD) present indications of psychiatric conditions. These diagnoses are also highly prevalent among people who are admitted to jails, but research conducted with this population is limited, due in part to the challenges associated with gaining access to local detention centers. This paper aims to examine the patterns of psychiatric conditions, OUD, and MUD among an understudied population to help inform the development of service delivery systems.

Design/methodology/approach
The present study was designed to assess the prevalence of OUD, MUD and common psychiatric conditions in a large sample of adults (n = 846) collected from four local jails. Diagnostic patterns were evaluated according to the current criteria established in the Diagnostic and Statistical Manual of Mental Disorders (5th ed; American Psychiatric Association, 2013).

Findings
More than half (57.3%) of the sample met criteria for MUD, one-third (37.2%) exceeded the threshold for an OUD diagnosis and 15.7% were classified with both conditions. Participants who met criteria for both MUD and OUD were significantly more likely to experience symptoms of major depression [adjusted odd ratios (aOR) = 1.76, 9, confidence intervals (CI) = 1.16–2.67], post-traumatic stress disorder (aOR = 2.51, 1.64–3.83), panic attacks (aOR = 3.24, 95% CI = 2.05–5.13), obsessive compulsive disorder (aOR = 2.74, 95% CI = 1.66–4.51) and antisocial personality (aOR = 3.03, 95% CI = 1.97–4.64).

Originality/value
These results, which were derived from an understudied population of adults detained in local jails, indicate the co-–occurrence of MUD and OUD are associated with certain psychiatric conditions.
