Dynamics of infant white matter maturation from birth to 6 months
Authors: Risk Benjamin , Li Longchuan , Jones Warren , Shultz Sarah 
Published: February 2025

AbstractThe first months after a baby’s birth encompass the most rapid period of postnatal change in the human lifespan, but longitudinal trajectories of white matter maturation in this period remain uncharted. Using densely sampled diffusion tensor images collected longitudinally at a mean rate of 1 scan per 1.55 days, we measured non-linear growth and growth rate trajectories of major white matter tracts from birth to 6 months. Growth rates at birth were 6 to 11 times faster than at 6 months, with tracts less mature at birth developing fastest. When matched on chronological age, shorter gestation infants had less mature white matter at birth but faster growth rates than their longer gestation peers; however, growth trajectories were highly similar when corrected for gestational age. This is the first study to estimate white matter trajectories using dense sampling in the first 6 post-natal months, which can inform the study of neurodevelopmental disorders beginning in infancy.
Conformational Entropy of Intrinsically Disordered Proteins Bars Intruders from Biomolecular Condensates
Authors: Grigorev Vladimir , Wingreen Ned S. , Zhang Yaojun 
Published: February 2025

It was recently discovered that eukaryotic cells are host to a multiplicity of biomolecular condensates. These condensates typically contain protein and/or RNA components with intrinsically disordered regions (IDRs). While IDRs have been proposed and demonstrated to play many roles in condensate biology, we suggest here an additional crucial role of IDRs, which is to exclude unwanted “intruders” from condensates. This exclusion effect arises from the large conformational entropy of IDRs; i.e., there is a high free-energy cost to occupying space that would otherwise be available to the IDRs. By combining polymer theory with sticker-spacer simulations, we show that the relevant insertion free energy increases with the concentration of IDRs in the condensate as well as with intruder size, attaining a linear scaling with surface area for large intruders. We find that at realistic IDR concentrations, particles as small as the size of an average protein (4 nm in diameter) can be 97% excluded from condensates. To overcome this entropic barrier, molecules must interact favorably with condensate components to be recruited as clients. Application of the developed size-exclusion theory to biological condensates suggests that condensate IDRs may play a generic exclusionary role across organisms and types of condensates.

The role of the CFO in financial communication: implications for public relations and investor relations
Authors: Hoffmann Christian Pieter , Binder-Tietz Sandra , Bendahan Bitton Daniel 
Published: February 2025

PurposeMembers of the corporate C-suite are powerful and widely perceived communicators. Communication management research examines the role of the corporate communication function in facilitating the positioning of chief executive officers (CEO). The present study contributes to this research by extending the focus to another executive board member, the chief financial officer (CFO) and the domain of financial communication. It examines the role of the CFO in addressing financial audiences – compared to that of the CEO. It also analyzes the roles of the public relations (PR) and investor relations (IR) departments in facilitating CFO positioning.Design/methodology/approachThis study is based on an interview study of eight IR and PR professionals and a survey of 106 heads of investor relations and financial communication experts from listed companies in Germany, Switzerland and Austria.FindingsFindings show that CFOs are similarly visible in capital markets as CEOs. Their communicator roles differ according to task responsibilities, with CEOs focusing on strategy and CFOs conveying financial performance. While CEOs are more involved in press relations, CFOs focus on investor dialog. CFOs are less proactively positioned than CEOs. Also, CFOs are mostly positioned in the context of mandatory disclosure. PR departments influence CEO positioning more, while IR departments commonly report to the CFO. Communicator roles are rarely formally defined and are subject to the executives’ preferences, which encumbers strategic communication management.Research limitations/implicationsThis study is based on cross-sectional survey data, which are subject to self-selection. The examined markets represent advanced capital markets with strict disclosure requirements. Findings indicate a lack of formalization in CFO positioning in the context of financial communication. This study also highlights the need to examine C-suite positioning beyond the CEO and the PR department.Originality/valueThis study contributes to research on C-suite communication by extending the perspective beyond the CEO and public relations. It also contributes to communication management research by highlighting how resource allocation and establishing rules shape the management practices applied to C-suite positioning. Finally, it contributes to financial communication research by empirically exploring the CFO’s communicator role.

PurposeFollowing the job demands-resources theory, this study investigates the role of female managers in enhancing employee well-being in terms of psychological health via workplace resources.Design/methodology/approachTo accomplish this objective, we conducted a comprehensive literature review to identify key IPS. Subsequently, a fuzzy-based algorithm was employed to prioritize these skills. Following this, we developed an algorithm based on Extreme Gradient Boosting (XGBoost) to predict the quality of workers’ IC. The efficacy of the XGBoost model was assessed by applying it to three real-life construction projects.FindingsUpon application of the model to the case studies, we made the following conclusions: (1) “Leadership Style,” “Listening,” “Team Building” and “Clarifying Expectations” emerged as significant skills and (2) the model accurately predicted workers’ IC quality in over 78% of the cases. This algorithm has the potential to preempt interpersonal conflicts, enhancing job-site productivity, team development and human resources management. Furthermore, it can guide construction managers in designing IPS training programs.Originality/valueThis study contributes to the existing knowledge by addressing the crucial connection between IPS and IC quality in construction projects. Additionally, our novel approach, integrating fuzzy logic and XGBoost, provides a valuable tool for IC prediction. By identifying significant IPS and offering predictive insights, this research facilitates improved communication and collaboration in the construction industry, ultimately enhancing project outcomes.

PurposeThis study aims to explore how autonomy, competence and relatedness impact work-based learning (WBL) motivation and engagement, contributing to enhanced employability skills. Additionally, it examines whether there are significant differences in these effects between students from STEM and social humanities.Design/methodology/approachThis study employed a correlational design with 284 undergraduate students, collecting cross-sectional data through validated surveys on autonomy, competence, relatedness, WBL and employability skills. The analysis utilized structural equation modeling partial least squares (SEM-PLS) and partial least squares-multi-group analysis (PLS-MGA) to explore WBL’s mediating role in the relationship between SDT components and employability skills, with comparisons across different academic faculties.FindingsThe results show that autonomy, competence and relatedness significantly enhance students’ employability skills through WBL. WBL serves as a mediator that strengthens student motivation and engagement, with notable differences in the effects between STEM and social humanities students.Practical implicationsHigher education institutions should integrate SDT principles autonomy, competence and relatedness into WBL programs to enhance employability skills. Moreover, these programs should be tailored to accommodate the distinct needs of students from various academic backgrounds, such as STEM and social humanities.Originality/valueThis study establishes a novel connection between self-determination theory (SDT) and the development of employability skills through WBL. It provides new insights into the mediating role of WBL in the relationship between SDT components and employability, highlighting the differential impacts across academic disciplines, particularly between STEM and social-humanities students.

Published: February 2025

PurposeThe purpose of this study is to explore how CEOs’ interpersonal communication styles on social media can effectively enhance the relationship with employees and increase their engagement on social media platforms.Design/methodology/approachAn online survey was conducted with 404 full-time employees working in corporations across various industries in the US. Only employees who “follow” their company’s CEO on social media were included in the study.FindingsCEOs’ use of a conversational tone on social media helps employees perceive them as approachable and interactive leaders, thereby improving the quality of the CEO-employee relationship and increasing employees’ engagement on social media. CEOs’ personal disclosures on social media were found to promote employees’ perceptions of CEO approachability only when paired with a conversational communication style.Research limitations/implicationsOur study offers theoretical implications for communication and media literature by highlighting the potential of CEOs as chief “engagement” officers, capable of leveraging online platforms (i.e. social media) to foster employee interactions and support.Practical implicationsThis study provides CEOs and communication practitioners with practical guidelines for using social media for both professional and social purposes as a crucial tool for internal relationship management.Originality/valueThis study is one of the first empirical attempts to examine the value of CEO social media communication as a key tool for building and maintaining quality employee–CEO relationship and engagement.

Urban planning for wildlife connectivity: A multispecies assessment of urban sprawl and SLOSS renaturalization strategies

Published: February 2025

Abstract

Urban areas are under constant pressure to accommodate more people, leading to an increase in built surface, further reducing and fragmenting wildlife habitat areas within and around cities. Nonetheless, wildlife populations may persist by using a network of habitat fragments, such as urban green areas, but only if functionally interconnected. Therefore, a proactive approach considering prospective landscape connectivity changes, following proposed developments, and potential mitigation strategies is needed.

We predicted present‐day and prospective landscape connectivity for six taxa, in the Greater Toronto Area, under landscape changes across three future scenarios which include the conversion of agriculture to developed land with (1) no mitigation strategies, (2) renaturalization of single‐large areas and (3) renaturalization of small and widespread areas. We used Omniscape to identify shared movement corridors across taxa, and Graphab to estimate the importance of each habitat patch for the overall connectivity (IICk), the isolation degree of habitat patches (node degree) and the distribution of stepping‐stone pressure (betweenness centrality). We validated our connectivity assessment through a road mortality risk assessment near the predicted present‐day movement corridors.

Without mitigation strategies, the proposed developments will increase the isolation of currently near‐isolated patches and the importance of nearby patches as stepping‐stones. There will be a shift in the distribution of movement corridors to remnant green areas within newly developed land, and the fragmentation of three key corridors connecting peripheral areas to inner‐city forested areas. Mitigation strategies with small and widespread renaturalized green areas provided the best outcome in terms of connectivity and can compensate habitat loss following new developments.

The validation analysis supported our connectivity modelling assessment and revealed that road mortality risk was elevated near roads intersecting movement corridors. This finding strongly indicates that roads act as barriers to connectivity and should be explicitly addressed in wildlife connectivity strategies, such as natural heritage or greenspace planning.

Synthesis and applications. Notably, smaller but widely distributed natural areas can serve as a practical and effective management strategy for balancing the trade‐offs among economic costs, urban expansion and habitat conservation. To effectively support biodiversity conservation goals, such as the 30 × 30 target, these smaller natural areas should ideally be connected to nearby larger natural areas through natural corridors or mitigation infrastructure.
Ethnic Minority Representation After the 2024 General Election: Does Ethnicity No Longer Matter?
Authors: Sobolewska Maria 
Published: February 2025

AbstractWith a new record of ethnic minority MPs elected in 2024, Westminster is nearly fully representative of voters of ethnic minority origins. This outcome was not entirely dependent on Labour's landslide, with pre‐election analyses showing that diversity of MPs would have improved with all possible election results. The question is: does this parity in descriptive representation mean that race and ethnicity no longer matter for electoral outcomes? Using the example of voters’ evaluations of Rishi Sunak, this article shows that this is not the case. Sunak's ethnicity did matter for a small minority, with a clear ‘ethnicity bonus’ from Indian‐origin voters. He also received more support from ethnocentric voters and less so from racially liberal voters, more in keeping with his politics than his ethnicity. This suggests attitudes to ethnicity matter more than the ethnicity of politicians.
Energy Use, Energy Depletion, and Environmental Degradation: Exploitation of Natural Resources
Authors: Chen Nan , Usman Muhammad 
Published: February 2025

ABSTRACTThe energy demand has led to the depletion of fossil fuels, resulting in environmental degradation and negative impacts on human health. The depletion of natural resources has severe implications for the environment and human life. Energy use, depletion, and environmental degradation are major threats to the world's natural resources. As the global population grows, the demand for energy continues to increase. This increased demand for energy has led to increased energy consumption, resulting in energy depletion and environmental degradation. This article examines the impact of energy use and energy depletion on the natural resources depletion in China from 1973 to 2019, using CO2 emissions and forest rents as moderating variables. To this end, a time‐series analysis is employed to analyze the data from the World Development Indicators. The results suggest that natural resource depletion and energy use increase CO2 emissions, energy depletion, and energy use, while forest rents are negatively correlated with natural resource depletion. These significant results further prove the importance of managing natural resources and energy in China. Protecting and preserving natural resources is essential to reducing energy use and conserving resources. China should introduce policies to protect and preserve natural resources, such as setting up protected areas for wildlife, limiting the exploitation of resources, and encouraging sustainable use.
