Bioenergetic signature of Synaptic mitochondria
Authors: Faria-Pereira Andreia , Morais Vanessa A. 
Published: November 2024

ABSTRACTSynaptic transmission is the most energy-demanding processes in the brain and here we show that mitochondria have developed specific properties to efficiently support neurotransmission. It is a known fact that mitochondria at synapses need to be able to deal with a dynamic range of energetic needs overtime and to adapt between resting and high stimulation conditions. However, how mitochondria are adjusting to this requirement was not yet clear. Here, we show that synaptic mitochondria have a distinct bioenergetic profile presenting a stronger ability to respond to respiratory stimulus. These features are explained by a dichotomic Complex I activity pattern where synaptic mitochondria present a decreased enzymatic activity of individual Complex I, yet mitochondria at synapse present a dramatically enhanced Complex I+III combined activity. These bioenergetics features may endow synaptic mitochondria with the necessary mechanisms to adapt to the flexible bioenergetic environment present at synapses.

Authors: Wu Yannian , Kim Euisoo , Zhang James J. , Li Fengyan , Duan Haixia 
Published: November 2024

PurposeGrounded in social cognitive theory, social exchange theory and “cognition-emotion-behavior intention” analysis framework, a theoretical model of cause-related sport marketing (CRSM) affecting consumers’ purchase intentions was constructed through a case study. This model was then empirically validated to confirm CRSM's impact on consumers' purchase intentions.Design/methodology/approachThis study embraces a mixed-methods approach that combines both qualitative and quantitative research methodologies to investigate the mechanisms through which CRSM influences consumers' purchase intentions.FindingsThe results indicate that: (1) consumers’ perception of CRSM has no direct impact on purchase intentions; (2) consumers’ perception of CRSM directly affects gratitude; (3) consumer gratitude acts as a complete mediator between perceived CRSM and purchase intentions.Originality/valueThese findings shed light on the role of gratitude in CRSM and offer practical guidance for sports enterprises in improving their philanthropic marketing strategies.

Published: November 2024

PurposeDespite the growing interest in closed-loop manufacturing, there is a lack of comprehensive frameworks that integrate product development, production processes, people and policies (4Ps) to optimize sustainable manufacturing performance. This study investigates the influence of the four Ps of closed-loop manufacturing systems (product development, production processes, people and policies) on sustainable manufacturing performance (SMP).Design/methodology/approachTo investigate the influence of the four Ps on SMP, a hybrid analytical model was employed, combining structural equation modeling (SEM) with artificial neural networks (ANN). Data were collected through a structured survey administered to 353 manufacturing firms in Malaysia. SEM was used to assess the relationships between the variables, while ANN was employed to capture nonlinear relationships and improve prediction accuracy.FindingsThe research findings demonstrate that product development practices, including eco-design, life cycle assessment and resource planning, exert the most significant influence on SMP. Furthermore, implementing green and lean manufacturing techniques, energy modeling and material utilization/toxicity planning significantly enhances sustainability outcomes. While the social setting (employee motivation, turnover and work–life quality) does not directly impact SMP, it plays a pivotal role in facilitating the implementation of internal environmental policies. Moreover, environmental management practices, both mandatory and voluntary, serve as intermediaries between the four Ps and SMP within closed-loop manufacturing systems.Practical implicationsThe findings offer valuable insights for policymakers, industry leaders and manufacturing organizations. By prioritizing product development, implementing green and lean manufacturing practices and fostering a positive social setting, organizations can significantly enhance their sustainable performance. Additionally, the study highlights the importance of effective environmental management practices in mediating the relationship between other factors and SMP.Originality/valueThis study contributes to the literature by providing a comprehensive framework for understanding the factors that drive sustainable manufacturing performance. The hybrid SEM-ANN model offers a robust and innovative approach to analyzing the complex relationships between the four Ps and SMP.

Published: November 2024

PurposeThis study aims to (1) develop an artificial intelligence (AI)-based model to accurately forecast rebar prices and (2) propose procurement strategies to reduce the subjectivity involved in rebar price trend forecasting and minimize procurement costs for construction project general contractors.Design/methodology/approachCorrelation analysis was used to identify the key factors influencing changes in rebar prices over time. An AI-based inference model, symbiotic bidirectional gated recurrent unit (SBiGRU), was developed for rebar price forecasting. The performance of SBiGRU was compared with other AI techniques, and procurement strategies based on the SBiGRU model were proposed.FindingsThe SBiGRU model outperformed the other AI techniques in terms of rebar price forecasting accuracy. The proposed rebar price forecasting model (RPFM) and procurement patterns, which integrate inventory management principles and rebar price forecasts, were demonstrated to effectively optimize procurement costs, realizing a remarkable 6.13% reduction in procurement expenses compared to the conventional monthly procurement approach.Research limitations/implicationsThe accuracy of AI models may be impacted by disparities in the data used for model training. Future research should explore approaches incorporating price predictions and order factors.Originality/valueThis study significantly extends the bounds of traditional rebar price prediction by integrating AI-driven forecasting with inventory management principles, highlighting the potential of AI-based models to improve construction industry procurement practices, reduce related risks and costs, optimize project operations and maximize project outcomes.

Authors: Shabbir Muhammad Salman 
Published: November 2024

Purpose
This study aims to examine the key factors influencing consumer behavioral intentions toward energy-efficient vehicles (EEVs) in the context of promoting renewable energy and achieving Sustainable Development Goals (SDGs). Specifically, it focuses on SDG 7 (“affordable and clean energy”) and SDG 13 (“climate action”). The research investigates how the theory of consumption values – functional, symbolic, emotional and conditional values – shapes consumers’ intentions, with attitudes toward EEVs as a mediating factor.

Design/methodology/approach
A quantitative research methodology was used, with data collected through structured surveys. The data was analyzed using partial least squares structural equation modeling (PLS-SEM) to assess the relationships between consumption values and consumer behavioral intentions toward EEVs. The mediating effect of attitudes toward EEV adoption was also examined in this model.

Findings
The study found that consumer behavioral intentions toward EEVs are significantly influenced by consumption values, with functional value having the greatest impact. Attitudes toward EEV adoption played a crucial mediating role in the relationship between consumption values and behavioral intentions. Symbolic, emotional and conditional values also contributed positively, though to a lesser extent than functional value.

Originality/value
This research offers novel insights into the factors driving consumer interest in EEVs, providing a comprehensive understanding of how consumption values shape attitudes and intentions. The findings provide practical value for policymakers and researchers in crafting strategies to accelerate EEV adoption, contributing to the achievement of global sustainability goals. The use of PLS-SEM enhances the rigor of the analysis, making this study a valuable contribution to both academic and practical discussions on sustainable transportation.

Authors: Hameli Kujtim , Aktaş Hakkı 
Published: November 2024

Purpose
This study examines the effects of organizational spirituality, leadership styles and organizational trust on employee well-being as explained by work engagement and job burnout. Specifically, the study aims to examine the moderating role of organizational trust on the relationships between these variables.

Design/methodology/approach
The study uses a quantitative approach and utilizes a survey for data collection involving 783 employees from Kosovo. Data analysis was conducted using structural equation modeling (SEM).

Findings
The research results show that organizational spirituality positively affects work engagement and negatively affects job burnout. Furthermore, both transformational and transactional leadership styles show a positive association with work engagement, while only transactional leadership is significantly associated with job burnout. The SEM results underscore that organizational trust does not moderate the relationship between organizational spirituality and employee engagement or job burnout. Organizational trust does, however, moderate the relationships between transformational and transactional leadership styles and both work engagement and job burnout.

Research limitations/implications
This study has several limitations, including the non-random sampling method and the cross-sectional nature of the study. In light of the findings, the implications of the study are discussed and recommendations for future studies are provided.

Originality/value
This study is an enrichment to the existing literature as it explores the subtle role of organizational trust as a moderator in the aforementioned relationships. It highlights the significant influence of organizational spirituality and leadership styles on work engagement and job burnout and provides new insights for researchers and practitioners alike.
Mobile robot localization method based on point-line feature visual-inertial SLAM algorithm
Authors: Xu Jintao , Fang Yu , Gao Weiwei , Liu Xintian , Shi Juanjuan , Yang Hao 
Published: November 2024

Purpose
The purpose of this study is to address the low localization accuracy and frequent tracking failures of traditional visual SLAM methods in low-light and weak-texture situations, and we propose a mobile robot visual-inertial localization method based on the improved point-line features VINS-mono algorithm.

Design/methodology/approach
First, the line feature information is introduced into VINS-mono. Subsequently, the EDlines line feature extraction algorithm is optimized with a short line merging strategy and a dynamic length suppression strategy to reduce redundant short lines and fragmented segments. In the back-end sliding window optimization, line feature reprojection errors are incorporated, and Huber kernel functions are added to the inertial measurement unit residuals, point-line feature residuals and loop closure constraints to reduce the impact of outliers on the optimization results.

Findings
Comparison and verification experiments are carried out on the EuRoC MAV Data set and real weakly textured environment. In the real low-light and weak-texture scenarios, the improved mobile robot localization system achieves over 40% higher accuracy compared to VINS-mono.

Originality/value
The main contribution of this study is to propose a new visual-inertial SLAM method combining point-line features, which can achieve good localization effect in low-light and weak-texture scenes, with higher accuracy and robustness.
Organizational strategy, abnormal cash holdings, and future operating returns
Authors: Magerakis Efstathios , Habib Ahsan 
Published: November 2024

PurposeThis paper empirically investigates (1) the association between business strategy and abnormal cash position and (2) the future performance implications of abnormal cash holdings conditional on business strategy for a sample of US firms.Design/methodology/approachWe use the firm-specific composite business score developed by Bentley et al. (2013) and examine its relationship with abnormal cash holdings. We employ the cash holding model of Opler et al. (1999) to determine the level of normal cash holdings with the residual being labeled as the abnormal cash holdings.FindingsUsing a sample of US firms, we confirm a positive and significant association between business strategy and abnormal cash holdings. We also reveal that a deviation from the estimated cash level can lead to an improved future performance but a prospector (defender) -type business strategy weakens (strengthens) the excess cash–firm performance relationship.Originality/valueWhile the prior evidence show the effects of business strategies on corporate cash holding, there is no evidence of the association between business strategy and abnormal cash holdings and the performance implications of the strategy-cash holdings nexus. Hence, through the lens of business strategy, this study aims to fill this gap in the literature.

Authors: Shahzad Faisal , Akhlaq Ather , Ghaffar Chaman 
Published: November 2024

PurposeThis study aims to investigate the factors influencing successful and unsuccessful succession in Pakistani family-owned businesses (FOBs), with a focus on the interplay between formal governance practices and socio-cultural dynamics. By examining key elements in succession planning and leadership transition, the study offers insights tailored to the unique challenges faced by FOBs in emerging markets such as Pakistan.Design/methodology/approachEmploying a multiple case study approach, this research examines generational transitions across ten Pakistani FOBs. Data were collected through semi-structured interviews with key family members involved in the succession process, with thematic analysis applied to identify patterns.FindingsThe findings indicate that proactive succession planning, formal governance mechanisms and thorough successor training are critical for achieving smooth leadership transitions in Pakistani FOBs. Companies that implement structured governance and clear succession processes experience fewer internal conflicts and greater business continuity. However, socio-cultural factors, such as seniority-based preferences and gender biases, present significant obstacles, often complicating the transition process. Additional challenges include resistance to modernized strategies, and sibling rivalry strongly influence succession outcomes in the Pakistani context and highlight the need for culturally sensitive governance approaches to improve business continuity.Practical implicationsPractical implications for family-owned businesses include early succession planning, structured governance mechanisms and comprehensive training for successors. Establishing family councils can minimize conflicts and align family goals. Addressing cultural biases, such as gender and seniority preferences, encourages merit-based succession, ensuring smoother transitions. These strategies enhance continuity, reduce disruptions and support sustained growth, particularly in culturally influenced contexts like Pakistani family-owned businesses.Originality/valueBy examining succession dynamics within the context of an emerging economy such as Pakistan, this study provides valuable insights into the unique cultural and organizational challenges facing FOBs. The findings enrich the understanding of succession in family enterprises and extend current knowledge on the influence of socio-cultural factors in business continuity.
Prisoner perceptions of the environmental impact on self-harm and suicidal behaviour
Authors: Nixon Lauren , Goldie-Chaplin Gemma 
Published: November 2024

Purpose
Improving prison safety by reducing self-harm and suicidal behaviour remains a government priority (Ministry of Justice, 2021). This involves developing a better understanding of the relationship between prison environments, self-harm/suicidal behaviour and the prison conditions supporting a reduction in such behaviour. Through interpretive phenomenological analysis, the authors aim to explore prisoners’ perceptions of one prison environment, considering if/how the environment has impacted prisoners need for support via the assessment, care in custody and teamwork (ACCT) process.

Design/methodology/approach
Data was collected through semi-structured interviews with seven prisoners at an adult male establishment who had not been on an ACCT since arriving there but had at least two active ACCT documents in the 12 months prior to transfer.

Findings
Analysis identified four superordinate themes: facilities, population, mentality and interaction with staff. This research increases understanding of specific factors contributing to prisoner’s lack of need for support via an ACCT document.

Research limitations/implications
A small sample within one prison for those convicted of sexual offences was used. Therefore, the findings are not fully generalisable to all establishments. The authors did not control for factors beyond the environment that could have contributed to prisoner’s lack of need for support via an ACCT document.

Practical implications
By conducting research, Forensic Psychologists are uniquely placed to increase research evidence to support the improvement of prison safety, whilst promoting its application in practice. Several recommendations about enhancing prison environments are made.

Originality/value
The findings provide insight into specific aspects of a prison environment that impacts prisoners’ level of self-harm and suicidal behaviour.
