Integrated local and systemic communication factors regulate nascent hematopoietic progenitor escape during developmental hematopoiesis
Authors: Shalaby Carson , Garifallou James , Thom Christopher S 
Published: October 2024

ABSTRACTMammalian blood cells originate from specialized hemogenic endothelial (HE) cells in major arteries. During the endothelial-to-hematopoietic transition (EHT), nascent hematopoietic stem cells (HSCs) bud from the arterial endothelial wall and enter circulation, destined to colonize the fetal liver before ultimately migrating to the bone marrow. Mechanisms and processes that facilitate EHT and the release of nascent HSCs are incompletely understood, but may involve signaling from neighboring vascular endothelial cells, stromal support cells, circulating preformed hematopoietic cells, and/or systemic factors secreted by distal organs. In this study, we used single cell RNA sequencing analysis from human embryonic cells to identify relevant signaling pathways that support nascent HSC release. In addition to intercellular and secreted signaling modalities that have been previously functionally validated to support EHT and/or developmental hematopoiesis in model systems, we identify several novel modalities with plausible mechanisms to support EHT and HSC release. Our findings paint a portrait of the complex interregulated signals from the local niche, circulating hematopoietic/inflammatory cells, and distal fetal liver that support hematopoiesis.
Assessing microstructural damage in paediatric aortic coarctation tissue during benchtop balloon angioplasty and stenting

Published: October 2024

AbstractEndovascular stenting of native aortic coarctation has become standard treatment for children and young adults due to the shorter hospital stay and recovery time, lower procedural risk and less invasive nature. However, despite these advantages, neonatal coarctation remains a surgically treated lesion, owing to the challenges of vessel growth and stent design. Plain old balloon angioplasty (POBA) of neonatal coarctation has been used as a treatment modality in the past but concern around vessel damage and aneurysm formation limited its widespread adoption. To-date, stenting has often been preferred over POBA treatment to minimise tissue damage but very little evidence has been gathered to establish the degree of tissue damage during intravascular procedures in neonatal coarctation tissue.The aim of this study was to perform balloon angioplasty and stenting on coarctation the aorta samples harvested at the time of surgery from neonatal patients and visualise the deformation under ultrasound guidance. From this, the novel collagen hybridizing peptide (CHP) was used to assess the level of collage denaturation and microstructural damage this tissue experienced when undergoing these procedures. The results demonstrate that balloon angioplasty singularly is not a viable treatment option at maintaining the lumen diameter unless higher levels of stretch are achieved to permanently deform the tissue. Five out of six neonatal coarctation samples were successfully stented with no stent failure, proving that stent insertion is a viable option to achieve the desired lumen diameter. In addition, for both procedures, increased collagen damage was observed with higher tissue strain. Overall, this work would suggest stent placement as the best option to achieve reliable lumen gain and to limit the level of the level of collagen damage when stretching the tissue to achieve the required lumen diameter.

ABSTRACTWildmeat is crucial for the food security of Indigenous Peoples and Local Communities, yet information about its nutritional profile remains scarce. This study systematically reviewed the impact of anatomical part and taxonomic class (mammals, birds, reptiles) on the nutritional composition of wildmeat. Using the PRISMA protocol, we selected articles from Web of Science, Scopus, and Medline/PubMed databases, with criteria including original articles on wild animal meat composition consumed by humans, excluding studies presenting secondary data or lacking detailed methodologies. We employed a quality questionnaire and concordance analysis (Fleiss’ Kappa = 1.00) for robustness. Artificial intelligence techniques (eg., K-Nearest Neighbors) estimated missing nutritional values in all 21 articles included in our study, covering 26 species and 10 nutrients. Results show statistically significant nutritional variations between anatomical parts and animal classes. Reptile viscera have over twice the fat content and triple the iron compared to muscles. Mammal viscera contain five times more omega-6 and selenium, four times more iron and manganese, and almost double the zinc compared to muscles. Among classes, bird muscles have over 90% higher fat content than mammal muscles and 20% higher than reptile muscles. Mammals have over 100% higher zinc levels than birds, and reptiles have over 400% more selenium than birds. No significant difference in iron content between mammals and birds was noted, likely due to bird slaughter methods. This study highlights the importance of wildmeat for food security. Importantly, we demonstrate an enormous variation in nutritional composition, underscoring how different anatomical parts and taxonomic classes can contribute to tackling different nutritional deficiencies. Additionally, it introduces a novel methodology for handling missing nutritional composition data, providing a comprehensive approach to understanding the nutritional value of wildmeat. Our findings can inform food security policies and wildlife management, balancing conservation and subsistence.
Maintenance of Bound or Independent Features in Visual Working Memory is Task-dependent
Authors: Cao Ruoyi , Deouell Leon Y. 
Published: October 2024

AbstractConflicting findings exist regarding whether features of an object are stored separately or bound together in visual working memory. This controversy is based on an implicit assumption about a default, or fixed, mode of working memory storage. In contrast, here we asked whether the anticipated task might determine the format in which information is maintained in working memory, consistent with its task-oriented function. To test this flexible maintenance hypothesis, we recorded EEG while subjects performed a delayed (Yes/No) recognition task with different requirements and loads. Across three experiments, we compared event-related potentials (ERPs) in conditions with and without the necessity of maintaining conjunctions between features, while controlling for differences in visual stimulation. In Experiment 1 (N=24), involving color-location conjunctions, we identified a delay-period effect characterized by a positive potential shift in central-parietal channels when conjunction was not required by the task. This pattern, distinct from the effect caused by an increased working memory load, was confirmed in Experiment 2 (N=23) with an independent group of subjects using a similar paradigm, while also controlling for the physical appearance of probes. Finally, the observation of color and location conjunction in Experiments 1 and 2 was extended to Color and Orientation conjunction in Experiment 3 (N=22). Collectively, these three experiments provided reliable evidence demonstrating that the maintenance of feature conjunctions in working memory, whether spatial (location) or non-spatial (non-location), depends on the task goal.HighlightsTask demands determine whether objects are represented as separate features or as conjoined items (maintenance format) in visual working memory.EEG recordings show differential activity despite similar stimulation, reflecting task demands.The effect of the task is evident in the early stages of working memory processing.Flexibility in maintenance format was observed for both color-location and color-orientation conjunctions.The findings challenge the notion of fixed maintenance format during visual working memory.
Antecedents and consequences of distributed leadership in Indian higher education
Authors: Madan Anishya Obhrai , Jain Ajay K. , Bolden Richard 
Published: October 2024

PurposeThe concept of distributed leadership (DL) has been widely advocated within higher education (HE). Yet, there have been few empirical investigations and little theory development outside Western contexts to date. This study presents a unique conceptualisation of DL and tests it empirically in India.Design/methodology/approachThis study tests a moderated-mediation model by exploring the antecedents and consequences of DL in HE. Standardised questionnaires were drawn from literature and completed by a sample of 269 respondents from six top-ranked (elite) Indian higher education institutions (HEIs). Structural equation modelling (SEM) and multi-group analysis techniques were used to analyse the data.FindingsResults demonstrated that empowering power structure (EPS) is positively related to DL, whilst participation in decision-making (PDM) strengthened this relationship. Further, it is also noted that DL mediates the relationship between EPS and behavioural outcomes of employee voice and silence.Practical implicationsThe findings suggest that a DL approach can be effective at enhancing employee voice and reducing employee silence within HEIs in (and perhaps beyond) India. The research also suggests that where institutions implement EPS alongside opportunities for PDM, this can help foster and sustain DL.Originality/valueBy exploring antecedents (EPS and PDM) and consequences (voice and silence), this paper presents a novel approach to studying DL. The focus on Indian HE offers a more nuanced empirical understanding of DL in a non-Western context.
Blockchain technology and consumers’ organic food consumption: a moderated mediation model of blockchain-based trust and perceived blockchain-related information transparency
Authors: Duong Cong Doanh , Nguyen Thanh Hieu , Ngo Thi Viet Nga , Dao Thanh Tung , Tran Nhat Minh 
Published: October 2024

Purpose
While the application of blockchain technology in the organic food supply chain has been increasingly recognized, the extant knowledge of how blockchain-driven traceability influences consumer perceptions and purchase intentions remains underexplored. Grounded in the stimulus-organism-response theory, this study aims to construct a moderated mediation model to examine blockchain-enabled traceability’s direct and indirect impacts on organic food purchase intention through perceived blockchain-related information transparency, considering the moderating role of blockchain-based trust.

Design/methodology/approach
A purposive sample of 5,326 Vietnamese consumers was surveyed using the PROCESS macro to test the proposed hypotheses.

Findings
The findings indicate that blockchain-enabled traceability significantly enhances perceived blockchain-related information transparency, which positively influences organic food purchase intention. Furthermore, blockchain-based trust was found to positively moderate both the direct effect of transparency on purchase intention and the indirect impact of traceability on purchase intention through transparency.

Practical implications
Practical and managerial insights for stakeholders in the organic food sector are also discussed.

Originality/value
These results contribute to the literature by extending the stimulus-organism-response model to the context of blockchain technology in supply chains and highlighting the critical role of trust in moderating the effectiveness of technological innovations.
Corporate sustainability communication to promote pro-environmental behaviour: lessons learned from Balinese women in Indonesia
Authors: Yudarwati Gregoria A. 
Published: October 2024

PurposeThis study aims to (1) examine corporate sustainability communication that promotes pro-environmental behaviour and (2) explore women’s experiences and expectations in relation to sustainability communication. Based on the findings, the study proposes a sustainability communication model that can facilitate the needs of both companies and women.Design/methodology/approachA case study was conducted to examine sustainability communication within the support waste management project of one company in Bali, Indonesia. Following the appreciative inquiry method, focus group discussions involving Balinese women and in-depth interviews were conducted to discover the best experiences and most appropriate ways to participate in waste management initiatives.FindingsThe findings show a gap between women’s understanding of sustainability issues and the information provided by the company. The company and women construct their own understandings of sustainability issues, and each has different capacities, needs, interests and values. This study contends sustainability communication as a process for co-creating meaning. It should begin by using the livelihoods and tangible impacts on women groups as the entry point.Research limitations/implicationsThe proposed framework suggests communication intervention that acknowledges the importance of community participation and empowerment as well as three levels of impact: for themselves, their environment, and their communities. This study also recommends further studies in different contexts, as this study was conducted in collectivist rural communities.Originality/valueThe proposed framework accentuates the value of communication processes and management as well as sustainability outcomes, and considers women as actors, rather than as objects.

Published: October 2024

Purpose
This study aims to investigate the relationship between emergency response times and crash severity in New York City, focusing on spatial disparities and their implications. It examines how these disparities impact disadvantaged neighborhoods, particularly regarding traffic safety and emergency service accessibility.

Design/methodology/approach
The research uses comprehensive spatial analysis techniques, including hotspot mapping, network analysis for travel time modeling, local bivariate correlation analysis and service area calculations. It maps crash data alongside emergency facility locations, considering peak-hour traffic. The Area Deprivation Index (ADI) is integrated to evaluate socioeconomic factors influencing accessibility. This approach provides a nuanced understanding of how emergency response times correlate with crash severity at the census block level, accounting for socioeconomic disparities.

Findings
This study reveals significant disparities in emergency response times across New York City. In high-poverty, predominantly minority areas, response times are 2–3 min longer than average, correlating with a 15% increase in severe injury rates. Over 20% of neighborhoods show correlations between response times and crash severity, with positive linear (5.51%), negative linear (10.72%), concave (2.44%) and convex (2.80%) relationships. Blocks with positive linear relationships have a mean ADI rank of 3.918. During peak hours, 69.7% of Manhattan blocks show negative relationships, the highest among boroughs.

Originality/value
This research highlights spatial justice issues in urban emergency response systems, emphasizing the need for localized, data-driven planning and infrastructure adjustments. By integrating the ADI, the multifaceted approach reveals the complex dynamics of socioeconomic factors and emergency service accessibility that have not yet been investigated in diverse urban communities.
Green technology acquisition strategies for chemical enterprises considering competition effects and spillover effects

Published: October 2024

PurposeGreen technology, characterized by its environmentally friendly attributes and sustainable practices, has emerged as a crucial tool in harmonizing the economic and ecological benefits. However, the challenge lies in selecting the most effective strategies for acquiring green technology. This paper aims to explore how chemical enterprises choose green technology acquisition strategies across diverse scenarios.Design/methodology/approachConsidering the influence of competition effects, spillover effects and their interactions on selecting green technology acquisition strategies, this paper develops three decision models (independent R&D, cooperative R&D and technology introduction). Drawing on the duopoly game theory as its theoretical framework, this paper delves into the examination of the economic and environmental benefits within distinct scenarios.FindingsCooperative R&D excels in promoting green technology R&D when spillover effects are strong, while independent R&D demonstrates superiority when spillover effects are weak. The threshold for the strength of spillover effects is related to competition effects. Additionally, cooperative R&D typically yields greater financial advantages than independent R&D and technology introduction. Moreover, the economic and environmental benefits may not be optimized simultaneously. Only enterprises that satisfy low competition and spillover effects as well as high competition and spillover effects, can achieve win-win economic and environmental benefits.Originality/valueAlthough green technology R&D and introduction are alternative strategies, they have typically been considered separately in prior literature. This study attempts to incorporate green technology R&D and introduction into a strategic system to investigate the selection of green technology acquisition strategies, taking into account competition effects, spillover effects and their interactions.
Time-variation in bank income and expense betas
Authors: Brigida Matt , Brigida Kathleen 
Published: October 2024

PurposeTo determine whether banks are able to hedge interest rate risk by matching interest income and expense betas each year, or only on average over longer time periods.Design/methodology/approachWe use state-space methods to estimate time-varying income and expense betas at the yearly frequency.FindingsWe find evidence that banks do match interest income to expense betas at the annual frequency, and the largest banks do the best job of matching interest income to expense sensitivities over time. Conversely, the smallest banks have the largest lag in matching interest income betas to changes in expense betas and have the largest net interest margins (NIM) sensitivity to the short-term rates.Originality/valuePrevious research was limited to constant deposit betas.
The intermorph breeding system is responsible for reproductive success in heterostylous Nyctanthes arbor‐tristis L.
Authors: Chaudhary Neha , Ghosh Dipayan , Kumar Narendra 
Published: October 2024

AbstractHeterostyly is a specialized reproductive system associated with self‐ and intramorph incompatibility. It reinforces the intermorph breeding system in heterostylous plant species. However, distyly has not been comprehensively studied in Nyctanthes arbor‐tristis. The present study demonstrates the floral traits, breeding system, fruit and seed set, and morph ratio in distylous N. arbor‐tristis. The length of style and filament showed reciprocal herkogamy between long style (L‐morph) and short style (S‐morph). Flower size, corolla tube size, stamen and anther length, ovary length, and pollen diameter were larger in S‐morph. However, the style was longer in L‐morph. Our results demonstrated strongly incompatible self‐ and intramorph pollination combinations. The intermorph pollination was compatible, showing normal pollen tube growth throughout the style and ovary. The embryo formation was also higher in intermorph interaction. Moreover, the fruit setting was higher when the intermorph plants grew in the vicinity of natural conditions. Collectively, all data indicate that N. arbor‐tristis is a distylous species with a self‐incompatible breeding system, resulting in less seed formation in nature.
