ABSTRACTGE-BOLD contrast stands out as the predominant technique in functional MRI experiments for its high sensitivity and straightforward implementation. GE-BOLD exhibits rather similar sensitivity to vessels independent of their size at submillimeter resolution studies like those examining cortical columns and laminae. However, the presence of nonspecific macrovascular contributions poses a challenge to accurately isolate neuronal activity. SE-BOLD increases specificity towards small vessels, thereby enhancing its specificity to neuronal activity, due to the effective suppression of extravascular contributions caused by macrovessels with its refocusing pulse. However, even SE-BOLD measurements may not completely remove these macrovascular contributions. By simulating hemodynamic signals across cortical depth, we gain insights into vascular contributions to the laminar BOLD signal. In this study, we employed four realistic 3D vascular models to simulate oxygen saturation states in various vascular compartments, aiming to characterize both intravascular and extravascular contributions to GE and SE signals, and corresponding BOLD signal changes, across cortical depth at 7T. Simulations suggest that SE-BOLD cannot completely reduce the macrovascular contribution near the pial surface. Simulations also show that both the specificity and signal amplitude of BOLD signals at 7T depend on the spatial arrangement of large vessels throughout cortical depth and on the pial surface.

ABSTRACTBackgroundGestational protein intake restriction induces long-lasting harmful outcomes in the offspring’s organs and systems.AimsThis study sought to evaluate the effects of protein restriction during pregnancy and breastfeeding in 42-day-old male offspring on the structure of the hippocampus, behavior tests related to memory and emotions, and the influence of an enriched environment on these parameters.Results and DiscussionThe current study demonstrated that maternal protein restriction during neural development causes crucial morphological changes in the hippocampus, making the LP offspring vulnerable to specific neural disorders in adulthood. In addition, it supports the ‘selfish brain’ theory, a paradigm that postulates the brain maintains its mass ‘selfishly’ by reallocating resources from other body parts when faced with nutritional stress. However, the hippocampus cellularity pattern was profoundly altered, significantly reducing the number of neurons after the breastfeeding period. This may expand the understanding of nutritional stress affecting the brain area’s constitution and its supposed effects on posterior behavioral disorders. Here, reciprocal data was observed between brain masses, changes in the hippocampus cell pattern, and decreased body mass in the LP progeny.In conclusionit was demonstrated that neuronal composition and structure profoundly modified by dietary restriction are surprisingly restored from primordial cells by exposure to the enriched environment. In addition, we must emphasize that although we have observed a significant reduction in the number of neurons after gestational and breastfeeding periods, we demonstrated for the first time a substantial reduction in the fear-reflecting behavior, which an enriched environment exposure may revert. The enriched environment also significantly modified the discrimination ratio, increasing the ability of both progenies to discriminate between novel and familiar objects in a short time associated with reverse abnormal hippocampus cell patterns. These findings underscore the potential for environmental interventions to mitigate the effects of early=life nutritional stress on brain development and behavior.
The mediating role of organizational learning culture in the nexus of human resource development practices and employee competencies
Authors: Otoo Frank Nana Kweku 
Published: May 2024

PurposeA learning-focused culture promotes creativity, innovativeness and the acquisition of novel insights and competencies. The study aims to explore the relationship between human resource development (HRD) practice and employee competencies using organizational learning culture as a mediating variable.Design/methodology/approachData were collected from 828 employees of 37 health care institutions comprising 24 (internationally-owned) and 13 (indigenously-owned). Construct reliability and validity was established through a confirmatory factor analysis. The proposed model and hypotheses were evaluated using structural equation modeling.FindingsData supported the hypothesized relationships. The results show that training and development and employee competencies were significantly related. Career development and employee competencies were significantly related. Organizational learning culture mediates the relationship between training and development and employee competencies. However, organizational learning culture did not mediate the relationship between career development and employee competencies.Research limitations/implicationsThe generalizability of the findings will be constrained due to the research’s health care focus and cross-sectional data.Practical implicationsThe study’s findings will serve as valuable pointers to policy makers and stakeholders of health care institutions in developing system-level capacities that promote continuous learning and adaptive learning cultures to ensure sustainability and competitive advantage.Originality/valueBy evidencing empirically that organizational learning culture mediates the relationship between HRD practices and employee competencies the study extends the literature.

Authors: Alazzani Abdulsamad , Albitar Khaldoon , Hussainey Khaled 
Published: May 2024

Purpose
This study aims to examine the association between chief executive officers’ (CEOs) characteristics and sell-side analysts’ recommendations.

Design/methodology/approach
This study uses a sample of firms listed on the London Stock Exchange and uses two databases, Capital IQ and BoardEx to study the above relationship. A variety of regression analyses are used in the empirical models, including ordinary least squares, fixed effect, random effect, Tobit, Logit and generalized method of moments.

Findings
The authors find that firms with CEOs who had a wider network size and firms with foreign CEOs receive favorable investment recommendations. Further, firms with CEOs who have more time to retire are more likely to receive favorable investment recommendations. However, the authors find that firms with CEOs with more qualifications receive unfavorable recommendations and female CEOs are not affecting investment recommendations.

Originality/value
Ultimately, this study demonstrates the importance of CEO characteristics for sell-side analysts who play an important role in the stock markets.
How perceived transparency in information system development processes improves project quality in agile IT enterprises
Authors: Lee Philip Tin Yun , Lee Alice Jing , Chau Michael , Deng Bingjie 
Published: May 2024

PurposeWith the increasing agility of IT enterprises, it is crucial to identify suitable managerial strategies for controlling information system development (ISD) projects in the new agile working environments. These environments are characterized by the collaborative nature of work and the recurring nature of communication. This study aims to explore how perceived transparency in ISD processes, controlled by transparency strategies, impacts project quality.Design/methodology/approachIn collaboration with a firm that implemented a customized Scaled Agile Framework, questionnaires were distributed to employees involved in ISD projects. The goal was to understand the influence of perceived transparency in ISD processes on project quality.FindingsOur research demonstrates that perceived transparency in ISD processes enhances project quality through knowledge exchange by strengthening goodwill trust among team members. Additionally, transparency improves project quality through client feedback by strengthening competence trust of clients toward the team. Goodwill trust of clients toward the team and competence trust among team members have less impact on project quality enhancement.Originality/valueThis study reveals the nomological network among the perceived transparency, different types of trust among stakeholders, social interactions among stakeholders, and project outcomes in agile ISD environments. This nomological network has been overlooked by previous studies that biased toward top-down, interorganizational communication. It highlights that not all types of trust among stakeholders are involved in the processes through which perceived transparency influences ISD project quality in agile working environments. Additionally, it exposes the limitations of transparency strategies for controlling projects in agile IT enterprises.

Authors: Madhala Prashanth , Li Hongxiu , Helander Nina 
Published: May 2024

PurposeThe information systems (IS) literature has indicated the importance of data analytics capabilities (DAC) in improving business performance in organizations. The literature has also highlighted the roles of organizations’ data-related resources in developing their DAC and enhancing their business performance. However, little research has taken resource quality into account when studying DAC for business performance enhancement. Therefore, the purpose of this paper is to understand the impact of resource quality on DAC development for business performance enhancement. Design/methodology/approachWe studied DAC development using the resource-based view and the IS success model based on empirical data collected via 19 semi-structured interviews.FindingsOur findings show that data-related resource (including data, data systems, and data services) quality is vital to the development of DAC and the enhancement of organizations’ business performance. The study uncovers the factors that make up each quality dimension, which is required for developing DAC for business performance enhancement.Originality/valueUsing the resource quality view, this study contributes to the literature by exploring the role of data-related resource quality in DAC development and business performance enhancement.
The impact of board capital on total value reporting: evidence from the Australian health care sector
Authors: Liu Zihan , Abhayawansa Subhash , Jubb Christine 
Published: May 2024

PurposeThis study investigates the association between board gender diversity and multiple directorships, two board characteristics representing human, social and relational capital and the extent to which corporate reporting (using the double materiality principle) explains value creation for the organization, environment, society and the economy, which we define as total value reporting.Design/methodology/approachThis study uses a disclosure index developed based on the Integrated Reporting Framework and the Global Reporting Initiative (G4) guidelines to analyze disclosures made using the double materiality principle and reflect the value created by companies. The sample includes corporate reports of 102 Australian Securities Exchange (ASX) companies in the Health Care sector. Ordinary least squares regression analyses test the relationship between board gender diversity and multiple directorships and the quality of total value reporting (and its subcomponents) with appropriate control variables.FindingsFindings reveal that human, social and relational capital formed through multiple directorships and gender-diverse boards is positively related to the quality of total value reporting. Results hold for alternative measures and sensitivity tests of gender diversity and multiple directorships.Practical implicationsOur study reveals that (1) the <IR> Framework, when combined with the GRI Framework, effectively measures connected information quality under a double materiality perspective for total value reporting; (2) enhancing board effectiveness for total value reporting is achievable by increasing female directors and those with multiple directorships; (3) limitations in accessing experienced directors, particularly women, do not disadvantage countries like Australia and (4) directors holding multiple board positions are pivotal in disseminating best practices in corporate governance and reporting across various companies and industries.Social implicationsOur research reveals that gender diversity on corporate boards transcends mere representation, significantly enhancing how firms articulate their value to stakeholders. This finding underscores the urgency for public policies to advocate for increased female board representation. Additionally, our findings indicate that board diversity, encompassing gender, experience, industry background and cultural perspectives, can elevate transparency in reporting, crucial for attracting global investors, particularly in emerging markets.Originality/valueOur study is an early attempt to examine total value reporting – underpinned by double materiality – which reports on how companies create value for themselves, the environment and society. It is one of the first to identify drivers of reporting based on double materiality.

PurposeThis study investigates the impact of coaching on manager/leader burnout using the conservation of resources theory, addressing a gap in the literature.Design/methodology/approachThe research examines the difference between two cohorts of leaders actively engaged with coaches and regresses coaching engagement on leader burnout while controlling for personality, leadership style and span of control.FindingsThe paper presents empirical evidence of the relationship, which finds a paradox in that those with coaches/mentors exhibit higher levels of burnout than those without.Originality/valueThe study offers an original perspective, highlighting the need for further empirical investigation into the dynamics between the role of a coach and leader burnout.
Planning Facebook message strategy and creative appeal for effective ad engagement – an exploratory study
Authors: Zimand Sheiner Dorit , Kol Ofrit , Levy Shalom 
Published: May 2024

PurposeStudying the effect of social media advertising on consumer engagement, this study analyzes the impact of shared-experience versus personal message strategies, informational versus transformational creative appeals and low-involvement products versus high-involvement products. It aims to determine how best to combine ad elements to affect consumer engagement on different levels.Design/methodology/approachUsing an online survey among 448 Facebook users, an experimental factorial design of 2 (message strategy conditions) X 2 (creative appeal conditions) X 2 (product types: TV vs. frozen pizza) was used. Each advertisement was evaluated on three facets of engagement: cognitive, psychological and behavioral.FindingsResults indicate that informational appeal is preferable for all conditions. The effectiveness of message strategy differs by product type, and interactions between message and appeal are significant only for the high-involvement product. Additionally, it indicates that message strategy is most significant in affecting behavioral engagement and not necessarily cognitive or psychological engagement.Practical implicationsTo develop effective Facebook ads, practitioners should use a personal/informational combination when working with high-involvement products and a shared-experience/informational combination when working with low-involvement products.Originality/valueAn original grid for integrating message strategy and creative appeal is constructed in this paper. Besides behavioral engagement, it also evaluates cognitive and psychological engagement. By comparing products with a high and low involvement level, it provides marketers with actionable recommendations to increase social media campaign effectiveness.
Have HR strategic partners left the building? The (new) role of HR professionals from a social-symbolic perspective
Authors: Cuel Roberta , Ravarini Aurelio , Imperatori Barbara , Antonelli Gilda , Torre Teresina 
Published: May 2024

PurposeThis manuscript explores the evolving roles of HR professionals amidst global megatrends and organizational transitions, focusing on the Italian context, which has experienced disruptive adoption of new forms of work such as remote and hybrid work. In this challenging scenario, our research aims to uncover if and how HR professionals are transforming their roles or maintaining the status quo in navigating organizational changes, dealing with the upcoming working scenario, and challenging conventional perceptions of HR practitioners.Design/methodology/approachThe study employs the social-symbolic work lens, that contributes to a deeper understanding of how HR professionals work to construct organizational life, the identities of employees, and the societal norms and assumptions that provide the context for organizational action. This perspective highlights HR professionals’ personal efforts, consisting of the emotional labor entailed in steering organizational transformations and, eventually, maintenance in a context where remote work has become prevalent. Data was collected through 16 online focus groups involving 76 HR professionals from Italian organizations.FindingsOur research offers two interrelated contributions to HR literature. First, we provide pieces of evidence on how HR practitioners act as agents of change in two emerging roles: the “Wannabe Hero” and the “Ordinary Hero”. This challenges the prevailing rhetorical discourse about the so-called HR business partner. Secondly, we delve into the persistent obstacles that hinder HR professionals from making a substantial impact in addressing radical changes. These findings will provide useful insights into effectively engaging HR practitioners as agents of change in organizational transformation, shedding light on praxis, structures, and their emotional work.Originality/valueThe paper analyzes HR professionals’ social-symbolic work, which offers an original contribution to the comprehension of the activities they carry on in practice and the emotions they have been experiencing. These influence both the way HR professionals play their role and the organizational and institutional environment.

Authors: Brandao Maicom Sergio , Godinho Filho Moacir 
Published: May 2024

Purpose
This study aims to investigate the evolution of terminology in supply chain management (SCM) and its implications for the field’s strategic orientation. It also aims to understand how SCM terms adapt to interdisciplinary contexts, reflecting shifts in theoretical and practical approaches within the discipline.

Design/methodology/approach
This study uses a systematic literature review and analyzes over 3,500 unique SCM-related terms extracted from approximately 33,000 abstracts. By using Descending Hierarchical Classification and factor analysis, the research methodologically identifies key shifts in terminology and discerns underlying patterns.

Findings
This study categorizes terminological variations in SCM into three main clusters: product–agent, performance objective orientation and structure. These variations signal not only linguistic changes but also strategic shifts in SCM understanding and practice. Notably, terms such as “green,” “sustainable” and “circular” supply chains have emerged in response to evolving internal and external pressures and trends. In addition, this paper offers a nuanced understanding of these terminological adaptations, proposing a reference framework for navigating SCM’s evolving lexicon and highlighting global usage and geographical and cultural nuances in SCM discourse.

Research limitations/implications
This paper presents a reference framework that complements existing SCM definitions, fostering a shared understanding of SCM variations on a global scale. This framework enhances cultural sensitivity within the field and underscores SCM’s adaptability and flexibility. These insights offer a nuanced view of SCM dynamics, benefiting researchers and practitioners alike. Beyond terminology, this study sheds light on the interplay between language and SCM strategy, providing a valuable perspective for navigating the evolving SCM landscape. The study’s scope is constrained by the analyzed abstracts. Future research could broaden this analysis to encompass more SCM literature or delve deeper into the implications of terminological changes.

Practical implications
This study offers practitioners a reference framework for navigating the evolving lexicon of SCM. This framework aids in understanding the strategic implications of terminological changes, enhancing clarity and context in both academic and practical applications.

Social implications
By acknowledging global usage and variations, the research underscores the impact of geographical and cultural nuances on SCM discourse. This global perspective enriches the understanding of SCM as a dynamic and culturally sensitive field.

Originality/value
This research is novel in its extensive and systematic exploration of SCM terminology. This study offers a comprehensive analysis of how language evolves in tandem with strategic shifts in the field, providing a unique perspective on the interplay between terminology and strategy in SCM.
