ABSTRACTAge-related cognitive decline associations with human electroencephalography (EEG) have previously focused on periodic activity. However, EEG is primarily made up of non-oscillatory aperiodic activity, which can be characterised with an exponent and offset value. In a secondary analysis of a cohort of 111 healthy participants aged 17 – 71 years, we examined the associations of the aperiodic exponent and offset with a battery of cognitive tests consisting of the Colour-Word Interference Test, Wechsler Adult Intelligence Scale IV Digit Span Test, Rey Auditory Learning Test, Delis-Kaplan Executive Function System Trial Making Test, and the Verbal Fluency Test. Using Principal Component Analysis and K-Means Clustering, we identified clusters of electrodes that exhibited similar aperiodic exponent and offset activity during resting-state eyes-closed EEG. Robust linear models were then used to model how aperiodic activity interacted with age and their associations with performance during each cognitive test. Offset by age interactions were identified for the Verbal Fluency Test, where smaller offsets were associated with poorer performance in adults as early as 33 years of age. Greater aperiodic activity is increasingly related to better verbal fluency performance with age in adulthood.

ABSTRACTVentilatory thresholds (VT1 and VT2) are critical in exercise prescription and athletic training, delineating the transitions from aerobic to anaerobic metabolism. More specifically, VT1 signifies the onset of lactate accumulation whilst VT2 signifies the onset of metabolic acidosis. Accurate determination of these thresholds is vital for optimizing training intensity. Fractal correlation properties of heart rate variability (HRV), particularly the short-term scaling exponent alpha 1 of Detrended Fluctuation Analysis (DFA-α1), have demonstrated potential for this purpose. This study validates the accuracy of commercial ventilatory threshold estimation algorithm (VT-algorithm) developed by Kubios. The VT-algorithm employs instantaneous heart rate (HR) relative to HR reserve and respiratory rate (RF), along with the DFA-α1. Sixty-four physically active participants underwent an incremental cardiopulmonary exercise test (CPET) with inter-beat interval (RR) measurements. DFA-α1 and the Kubios VT-algorithm were used to assess HR and oxygen uptake (VO2) at ventilatory thresholds. On average VO2 at true VT, DFA-α1, and VT-algorithm derived ventilatory thresholds were 1.74, 2.00 and 1.89 l/min (VT1) and 2.40, 2.41 and 2.40 l/min (VT2), respectively. Correspondingly, average HRs at the true VT, DFA-α1, and VT-algorithm thresholds were 141, 151 and 142 bpm (VT1) and 169, 168 and 170 bpm (VT2), respectively. When compared to the true thresholds, Bland-Altman error statistics (bias ± standard deviation of error) for the DFA-α1 thresholds were -0.26±0.41 l/min or -10±16 bpm at VT1 and 0.00±0.34 l/min or 1±10 bpm at VT2, whereas the VT-algorithm errors were - 0.15±0.28 l/min or -1±11 bpm at VT1 and 0.01±0.20 l/min or -1±7 bpm at VT2. HRV based VT determination algorithms accurately estimate ventilatory thresholds, offering insights into training zones, internal loading, and metabolic transitions during exercise without the need of laboratory equipment. The Kubios VT-algorithm, which incorporates instantaneous HR and RF along with DFA-α1, provided higher accuracy for VO2 and HR values for both VT1 and VT2.

The fabrication process is presented for a typical transition section located between each cylindrical corrugated waveguide structure comprising the wakefield accelerator module. The transition section includes couplers for extracting the 180 GHz TM01 accelerating mode and separate couplers for extracting the 190 GHz HE11 dipole mode, both modes induced by the electron bunch traversing the cylindrical corrugated waveguide structure. Extraction of the high-power accelerating mode reduces the heat load due to the subterahertz wave power dissipation within the corrugated accelerating structure. Extraction of the low-power dipole mode serves the purpose of detecting the electron bunch transverse oscillations within the wakefield accelerator and identifying the onset of beam breakup instability. Comprehensive testing of the fully functional transition section with an electron beam was done at the Accelerator Test Facility in Brookhaven National Laboratory which verified the functionality of the transition section.

Role of the triangle singularity in the isospin breaking process
J/ψ→ΛΛ¯π
and the possible evidence of
Σ*(12−)
states
Authors: Huang Qi , Ma Zi-Xuan , Wu Jia-Jun , Ping Rong-Gang , He Jun , Huang Hong-Xia 
Published: August 2024

In this study, the impact of triangle singularity is investigated in the isospin breaking process J/ψ→ΛΛ¯π. The triangle singularity is found to play a significant role in the process, resulting in the creation of a resonancelike structure around 1.4 GeV in the Λπ(Λ¯π) invariant mass spectrum. To amplify the impact of this triangle singularity, the presence of two Σ*(12−) states around 1.4 GeV and 1.6 GeV is essential, yet these states have not been definitively identified in the current baryon spectrum. We recommend that experiments, particularly the Beijing Spectrometer and the future Super Tau-Charm Factory, investigate the process J/ψ→ΛΛ¯π to offer direct evidence for our predicted triangle singularity and additional evidence regarding the Σ(12−) states.

Geometric and electronic structures of
Cs2BB′X6
double perovskites: The importance of exact exchange
Authors: Ji Yuyang , Lin Peize , Ren Xinguo , He Lixin 
Published: August 2024

A widely adopted computational protocol in contemporary materials research is to first relax materials' geometries using semilocal density functional approximations (DFA), and then determining their electronic band structures using the more expensive hybrid functionals. This procedure often works well, as the popular semilocal DFAs, such as the Perdew-Burke-Ernzerhof (PBE) generalized gradient approximation, yield rather good geometries for a wide range of materials. However, here we show that, for some of the lead-free halide double perovskites (HDPs) Cs2BB′X6 (B=Ag+, Na+; B′=In3+, Bi3+; X=Cl−, Br−), the validity of this common practice is questionable. We find that, for these HDPs, the geometrical structures, in particular, the B(B′)−X bond lengths predicted by PBE show large deviations from the experimental values. Additionally, the band gaps of some of these materials (specifically, the In-based HDPs) are sensitive to the B(B′)−X bond lengths. As a consequence, the band gaps obtained using the hybrid functionals (such as the Heyd-Scuseria-Ernzerhof functional) based on the PBE geometries can still be quite off, in particular, for HDPs with B′=In3+. The situation is significantly improved by using hybrid functionals with tuned portion of exact exchange, based on the geometries determined consistently under the same level of theory. The successes and failures of several popular exchange-correlation (XC) functionals are traced back to the so-called delocalization error, and can be quantitatively analyzed and understood via a three-atom linear-chain B−X−B′ molecular model. Finally, our findings provide a practical guide for choosing appropriate XC functionals for describing HDPs and point to a promising path for band structure engineering via doping and alloying.

Enhancing organic milk sales through cumulative power of product – extrinsic cues: empirical evidence from China
Authors: Zhao Liming , Wang Yingqiao , Cheng Xu 
Published: August 2024

PurposeTo examine the impact of manufacturer reputation, retailer reputation, and product price on consumers’ perceived quality and purchasing behavior regarding organic milk.Design/methodology/approachEmploying a 2 × 2 experiment, data were collected from 1,259 consumers in 32 provinces in China.FindingsWhen a low-reputation manufacturer sells products through a high-reputation retailer, it improves consumers’ perception of quality and positively influences their purchasing behavior. Interestingly, setting higher prices for products manufactured by low-reputation companies and selling them through high-reputation retailers did not significantly enhance consumers’ perceived quality and deter their purchasing behavior.Originality/valueThe analysis expands the framework for cue diagnosis. While the existing framework primarily focuses on the influence of cue-type combinations on perceived quality, it does not integrate purchasing behavior into the conceptual framework. This limitation hinders people understanding of the theoretical mechanisms underlying the use of cues in purchasing decisions. This paper address this by gradually introducing variables, such as retailer reputation and product price, into the baseline model, thereby extending this theory. In addition, this paper advances the marketing research literature within the business-to-business-to-consumer context by examining the additive effects of manufacturer reputation, retailer reputation, and product price on consumers’ perception of quality and purchasing behavior.

PurposeThe aim of this research was to explore and gain an understanding of the lived experiences of Black females transitioning from social work practice into academia and the support and barriers they experienced.Design/methodology/approachTo achieve this an adaptation of Wengraf (2004) Biographical Narrative Interview Model (BNIM) was employed alongside Braun and Clarke (2006) thematic analysis as foundation of the methodology employed in this study. Whilst the adverse issues relating to Black female academics is not new, the paper is original in the manner in which data was gathered.FindingsThe study identified four themes: (1) significance of early life, (2) passion for learning, (3) overcoming obstacles and (4) navigating academia. The case studies highlighted the various examples of resistance, rebellion and activism the Black female academics employed within UK universities. The paper concluded that despite the positive messaging from families and communities, about pursuing education, and the need for having a strong work ethic, the progress that can be achieved by Black female academics is limited due to the pervasive nature of racism, therefore dispelling the myth of meritocracy.Research limitations/implicationsThe research sample was small and therefore not easily generalisable to the whole population. The findings of the paper will need to be considered as a contribution of knowledge to the issue of structural racism.Originality/valueWhilst the adverse issues relating to Black female academics is sadly not new, the paper is original in the manner in which data was gathered. Namely, the academics were both researchers and the participants, therefore simultaneously providing and analysing the data.

Published: August 2024

PurposeArtificial intelligence (AI) technologies have led to significant transformations across industries and society, including the field of education. The integration of AI in educational settings has the potential to improve students' learning experience and support their individual competencies when paired with non-AI methods. Despite the growing importance of AI in modern education, there remains a noticeable research gap regarding its use in entrepreneurship education and the effects of Chatbots on students' entrepreneurial competencies. To address this gap, an exploratory study was conducted on undergraduate students who were tasked with using ChatGPT to improve their business model canvas.Design/methodology/approachThe chosen methodology aligned with the research purpose, aiming to explore the relationship between Generative AI and competencies. Due to the novel nature of the research problem, an exploratory study was conducted using a mixed methods approach. A survey with open- and closed-ended questions was designed, and statistical and text analyses were performed to interpret data and test identified propositions.FindingsThe findings of this study indicate that ChatGPT can enhance the types of students' entrepreneurial competencies considered in this study: spotting opportunities, creativity, vision, valuing ideas and ethical and sustainable thinking. The results show that ChatGPT can be particularly helpful to improve the ability of students of valuing ideas.Originality/valueOverall, this study highlights the potential of adopting ChatGPT in experiential learning methodologies for enhancing students' entrepreneurial competencies and improving their learning outcomes.

Authors: Saluja Omika Bhalla 
Published: August 2024

PurposeIt aims to understand crowdfunding’s effect on women’s entrepreneurship and summarize key findings, methods, and challenges women face in using crowdfunding for financing.Design/methodology/approachThis literature review examines 36 empirical studies on crowdfunding use by women entrepreneurs. It follows the PRISMA framework, using Scopus and citation tracking to categorize studies on crowdfunding’s potential to empower women financially and address their barriers to accessing finance.FindingsThe review identified seven key themes: opportunities and challenges for women in crowdfunding, equity crowdfunding’s potential, gender differences in crowdfunding outcomes, the role of social capital and networks, investor trust and decision-making, the influence of language, communication, and platform design, and the importance of considering intersectionality and context. Crowdfunding offers women entrepreneurs access to capital and helps them overcome traditional financing barriers. Women-led campaigns achieve comparable or even higher success rates compared to their male counterparts. However, under-representation, lower funding requests, pitching difficulties, and limited access to networks remain as challenges.Research limitations/implicationsThis study has limitations inherent to systematic reviews, including potential methodological flaws or biases in the included studies and the exclusion of relevant studies due to time and resource constraints.Practical implicationsCrowdfunding can be promoted as a viable financing option for women entrepreneurs and design targeted initiatives to support them. Building social capital, enhancing financial literacy, and creating networking opportunities can contribute to their success in navigating crowdfunding platforms effectively.Originality/valueThis review offers a comprehensive analysis of empirical studies conducted between 2012 and 2023. It provides up-to-date insights, identifies key themes, and offers actionable recommendations for policymakers and organizations seeking to support women entrepreneurs in effectively accessing and utilizing crowdfunding platforms.
Exploring the relationship between the built environment of prisons and the mental health of inmates
Authors: Gopinathan Bhavya , Vijayshankar Vaagdaa , Roy Sanghamitra 
Published: August 2024

Purpose
Around the world, prison complexes have always been fundamentally taxing environments. The strained atmosphere within these prisons often contributes to the deterioration of mental health, mostly those who may already be psychologically vulnerable. This paper aims to understand whether there exists a relationship between the built environment of prisons, particularly the central prisons of India and its effects on the mental health of inmates.

Design/methodology/approach
By means of literature reviews, the study parameters were found to be connectivity to nature, lighting, acoustics, colour, air quality and thermal comfort. The data collected through interviews and email correspondences with identified experts were analysed thematically using a deductive approach to derive a set of practical recommendations, which could be implemented in Indian prisons.

Findings
The built environment of prisons impacts the prison population by further contributing to depressive symptoms. The effects of the built space persist regardless of social factors. A well-designed environment is healthy for its occupants and would yield positive changes. However, it is not the sole contributor to depression; social interactions, prison management, societal acceptance and meaningful activities are equally relevant factors. The sole focus of this paper is the relationship between the built environment and the mental health of inmates.

Originality/value
There is a paucity of research into the intersection between prison architecture and the mental health of inmates in the Indian subcontinent. This paper that addresses the gap may have significant consequences on how criminal reform is perceived, and also encourage further research in this field.

Authors: Sharma Anil Kumar , Prashar Anupama , Sharma Ritu 
Published: August 2024

PurposeGlobally, the landscape of corporate carbon disclosures (CCD) is continually evolving as societal, environmental and regulatory expectations change over time. The goal of this study is to examine the challenges faced by Indian firms’ corporate carbon reporting (CCR). The literature recognized the hurdles to reaching net zero emissions and decarbonization, which are equally applicable to carbon disclosure (CD).Design/methodology/approachThe scope 3 emission disclosure barriers (S3EDBs) identified from the literature were ranked, and their relationships were discovered using the “Grey-based decision-making trial and evaluation laboratory” (Grey- DEMATEL) technique.FindingsThe key findings are the S3EDBs, the most prominent barriers, their interrelationships and important insights for managers of organizations in prioritizing the action area for scope 3 CD. Eight S3EDBs were categorized in terms of cause and effect, threshold value is calculated as 0.78. “Quality, and reliability of data,” “Government policies and statutory requirement on emission disclosure” and “Traceability and managing supply chain partners” are the most prominent S3EDBs.Practical implicationsThe results will help industry people in countries with emerging economies that have significant scope 3 carbon footprints. The managers can plan to deal with top S3EDBs as a step towards decarbonization and ultimately fighting climate change (CC).Originality/valueThis study is one of the first to rank these barriers to CD so that industry practitioners can prioritize their actions. The core contribution of this research is to detect the most significant S3EDBs and their interdependencies.
Platform openness and value: the mediation effect of user interaction and psychological distance
Authors: Saucède Florent , Vidal David 
Published: August 2024

PurposeLinking platform governance and value, the article explains how platforms manage openness, which gives users access and authority, to shape the user experience and orchestrate interactive value co-creation within their ecosystem.Design/methodology/approachWe adopted an abductive approach, drawing on an embedded multiple case study of platform-based local alternative food networks. The strong symbolic dimension embedded into that context allowed for a full exploration of value in its interactive nature.FindingsPlatform openness influences value creation directly, but also through two mechanisms: one behavioural, involving interactions between users and sides, and the other cognitive, involving users’ abstraction level. Value co-creation goes beyond the online space and occurs in complex sets of interactions between users. Digital platforms can thus generate intrinsic value co-creation that enhances their utility.Originality/valueWe have adopted a marketing channel theory reading of openness and mobilised a broader conception of value as well as cognitive science to explain how this key element of platform governance affects value creation.
Discriminations in remote work contexts: the pivotal role of diversity and equality management
Authors: Tommasi Francesco , Ceschi Andrea , Sartori Riccardo , Trifiletti Elena , Vignoli Michela , Dickert Stephan 
Published: August 2024

PurposeWe examined the effect of management practices on overt and subtle forms of discrimination in remote working contexts. Management practices (i.e. diversity and equality management systems) may influence employees’ perception of the diversity climate and affect the occurrence of discrimination.Design/methodology/approachTo empirically investigate these associations, we administrated an online questionnaire with self-report measures via a 3-wave longitudinal research design.FindingsData analysis of our sample of N = 153 remotely working employees show that when managers invest in equality and diversity practices, employees perceive their workplace as more inclusive (i.e. diversity climate). In turn, this reduces the occurrence of subtle discriminations. Conversely, this relationship was not significant for overt forms of discrimination.Originality/valueThis result indicates that creating a diversity climate is especially important when combatting subtle forms of discrimination in remote work contexts. We discuss the theoretical and practical implications of our findings in light of managerial studies on discrimination at work and psychological literature on virtual environment and social networking.
