Compositional architecture: Orthogonal neural codes for task context and spatial memory in prefrontal cortex
Authors: Park JeongJun , Holmes Charles D. , Snyder Lawrence H. 
Published: February 2025

AbstractThe prefrontal cortex (PFC) is crucial for maintaining working memory across diverse cognitive tasks, yet how it adapts to varying task demands remains unclear. Compositional theories propose that cognitive processes in neural network rely on shared components that can be reused to support different behaviors. However, previous studies have suggested that working memory components are task specific, challenging this framework. Here, we revisit this question using a population-based approach. We recorded neural activity in macaque monkeys performing two spatial working memory tasks with opposing goals: one requiring movement toward previously presented spatial locations (look task) and the other requiring avoidance of those locations (no-look task). Despite differences in task demands, we found that spatial memory representations were largely conserved at the population level, with a common low-dimensional neural subspace encoding memory across both tasks. In parallel, task identity was encoded in an orthogonal subspace, providing a stable and independent representation of contextual information. These results provide neural evidence for a compositional model of working memory, where representational geometry enables the efficient and flexible reuse of mnemonic codes across behavioral contexts while maintaining an independent representation of context.

AbstractBipolar disorder (BD) is increasingly recognized as a disorder with both mitochondrial dysfunction and heightened inflammatory reactivity, yet their contribution to neuronal activity remains unclear. To address these gaps, this study utilizes iPSC-derived cerebral organoids (COs) from BD patients and healthy controls to model disease-specific metabolic and inflammatory dysfunction in a physiologically relevant system. BD COs exhibited mitochondrial impairment, dysregulated metabolic function, and increased nod-leucine rich repeat and pyrin domain containing protein 3 (NLRP3) inflammasome activation sensitivity. Treatment with MCC950, a selective NLRP3 inhibitor, effectively rescued mitochondrial function and reduced inflammatory activation in both BD and control COs. Additionally, a Bioactive Flavonoid Extract (BFE) was explored as a potential therapeutic, demonstrating partial rescue of inflammasome activation. These findings highlight a mitochondria-inflammasome axis in BD pathophysiology and establish a novel platform for studying BD-associated cellular mechanisms, ultimately bridging the gap between molecular dysfunction and therapeutic development.

AbstractRegulators of chromatin accessibility play key roles in cell fate transitions, triggering onset of novel transcription programs as cells differentiate. In theDrosophilamale germ line stem cell lineage, tMAC, a master regulator of spermatocyte differentiation that binds thousands of loci, is required for local opening of chromatin, allowing activation of spermatocyte-specific promoters. Here we show that a cell-type specific surveillance system involving the multiple zinc finger protein Kmg and the pipsqueak domain protein Dany dampens transcriptional output from weak tMAC dependent promoters and blocks tMAC binding at thousands of additional cryptic promoters, thus preventing massive expression of aberrant protein-coding transcripts. ChIP-seq showed Kmg enriched at the tMAC-bound promoters it repressed, consistent with direct action. In contrast, Kmg and Dany did not repress highly expressed tMAC dependent genes, where they colocalized with their binding partner, the chromatin modeler Mi-2 (NuRD), along the transcribed regions rather than at the promoter. Mi-2 has been shown to preferentially bind RNA over chromatin (Ullahet al. 2022). We propose that at highly expressed genes binding of Mi-2 to the abundant nascent RNA pulls the Kmg/Dany complex away from promoters, providing a mechanism to effectively repress ectopic promoters while protecting robust transcription.

AbstractAlthough neuronal hyperexcitability is the primary mechanism underlying seizure activity in epilepsy, little is known about how different neuronal mechanisms at different organizational levels contribute to network hyperexcitability in the human epileptic brain. In this study, we determined a series of cellular and synaptic properties of layer V pyramidal neurons from neocortical tissue of patients with drug-resistant epilepsy that may contribute the hyperexcitable state associated with epilepsy. Using the whole cell, patch-clamp technique, and extracellular recordings, we determined the passive and active electrophysiological properties of layer V pyramidal neurons with regular spiking phenotypes from temporal, parietal, and frontal neocortices surgically resected from individuals with drug-resistant epilepsy. Also, the glutamatergic strength, the synchronicity between presynaptic volleys and field excitatory postsynaptic potentials, and short-term, frequency-dependent plasticity were determined at the synaptic level. Lastly, biocytin-filled pyramidal neurons were used to perform post hoc digital reconstructions and morphometric analyses. The collected data revealed that pyramidal neurons exhibit minimal spontaneous activity, similar resting membrane potentials, and input resistance values among the temporal, parietal, and frontal neocortices. Although frontal neurons were more hyperexcitable than temporal and parietal neurons, the firing output was comparable to that previously observed in non-pathological human tissue. The digital reconstructions confirmed the identity of pyramidal neurons and revealed alterations in dendritic complexity. In contrast, the analyses of the extracellular recordings uncovered significant desynchronization between presynaptic excitability and postsynaptic activity and loss of short-term depression in response to repetitive stimulation within the gamma range (30 Hz). Our data suggest that neocortical layer V pyramidal neurons from individuals with drug-resistant epilepsy are not necessarily hyperexcitable at the somatic level. Instead, synaptic alterations, such as synaptic desynchronization and a loss of frequency-dependent short-term depression may significantly contribute to the hyperexcitable state observed during seizure activity.

Because of the lack of a net magnetic moment, antiferromagnets possess a unique robustness to external magnetic fields and are thus predicted to play an important role in future magnetic technologies. However, this robustness also makes them quite difficult to control, and the development of novel methods to manipulate these systems with external stimuli is a fundamental goal of antiferromagnetic spintronics. In this work, we report evidence for a metastable reorientation of the order parameter in an antiferromagnetic semiconductor triggered by an ultrafast quench of the equilibrium order via photoexcitation above the band gap. The metastable state forms less than 10 ps after the excitation pulse, and persists for longer than 150 ps before decaying to the ground state via thermal fluctuations. Importantly, this transition cannot be induced thermodynamically, and requires the system to be driven out of equilibrium. Broadly speaking, this phenomenology is ultimately the result of large magnetoelastic coupling in combination with a relatively low symmetry of the magnetic ground state. Since neither of these properties are particularly uncommon in magnetic materials, the observations presented here imply a generic path toward novel device technology enabled by ultrafast dynamics in antiferromagnets.

Purpose
Large volumes of complex and diverse data sources present a tremendous barrier for big data applications (BDAs) in digital library in terms of processing and extracting relevant insights. The purpose of this study is to examine librarians’ perceptions of BDAs and management for digital library services in selected academic libraries in Kwara State.

Design/methodology/approach
The research design that was adopted in this study is the cross-sectional research design. The total population for this study is 58 (58) library professionals. Owing to the small population of this study, total enumeration sampling technique was adopted for this study. Hence, the sample size for this study is 58 (58). Questionnaire was used for data collection. Collected data were analyzed using descriptive statistics.

Findings
The study demonstrated that digital library services provided include virtual reference services, institutional repositories and personalized content recommendation. Also, the librarians were aware of BDAs like Apache Hadoop and Python. It was showed that BDAs are used for resource transfer, borrowing management, user needs, usage tracking and personalizing content recommendations. Results showed that open-source software and hardware, and training on handling diverse data sets are essential for the management of big data. Challenges associated with the use of BDAs include scalability limitations, complex data structures, lack of big data processing, power supply issues and data privacy.

Originality/value
This study provides unaddressed questions and gaps in the area of using BDAs for the provision of digital library services, especially in developing countries like Nigeria.
Are we there yet? Diversity management officers’ journey to strategic partnership
Authors: Nadiv Ronit , Kuna Shani 
Published: February 2025

PurposeThe organizational role of diversity management officers (DMO) is intertwined with the human resource (HR) profession and practices. Nonetheless, DMO ideologies, perspectives and challenges from the perspective of strategic human resource partnership have not been adequately addressed. This study aimed to explore the strategic role of DMOs using the comprehensive scholarly research on strategic HR partnerships. We suggest that DMOs’ limited success in promoting diversity may be due to a lack of strategic positioning of their role.Design/methodology/approachIn-depth, semi-structured interviews with 22 DMOs and HR practitioners were used to examine their day-to-day activities and interactions between their diversity-management and HR roles.FindingsThe findings indicate that DMOs direct their attention to diversity initiatives that address the personal needs and challenges of socially diverse employees and their managers. Thus, most DMOs operate on an administrative rather than a more strategic and transformational level, which also reflects their organization’s perspective on diversity.Research limitations/implicationsThe study was conducted using a medium-sized sample of practitioners in the Israeli business sector. This study focused on practitioners’ descriptions of their daily roles and did not include other organizational stakeholders, such as managers and employees.Practical implicationsAccording to the findings, the DMO role lacks strategic positioning. To better implement and promote diversity initiatives, DMOs should increase their strategic influence. Based on the strategic HR framework, we suggest four distinct roles that will enhance DMOs’ strategic positioning. We recommend practical improvements in DMOs’ practices and academic education, as well as training for practitioners.Originality/valueThis study adds to the scholarly understanding of DMOs and suggests a strategic framework for implementing organizational diversity.

Authors: Chen Yazhe , Shang Qingyu , Zhang Youwei , Yao Ying , Tomar Adesh Kumar , Long Risheng , Marian Max 
Published: February 2025

Purpose
This study aims to investigate the mechanical and tribological behavior of 70Mn steel with different laser re-melted textured patterns.

Design/methodology/approach
Laser surface re-melting (LSR) was used to manufacture various textured patterns (i.e. line, grid and mixed) on both the original and heat-treated 70Mn steel plates. The micro-hardness, microstructure, tensile strength, yield strength, elongation, coefficients of friction (COF) and worn morphologies were characterized to evaluate the impact of different textured patterns on the overall performance.

Findings
The results show that re-melted unit exhibited the highest surface hardness on the subsurface. The increase in surface hardness of the re-melted unit for the heat-treated 70Mn steel samples was much lower than that of the original ones. The re-melted textured patterns did not improve the tensile strength, yield strength and elongation of either original or heat-treated 70Mn steel samples. The re-melted textured patterns effectively reduced the average COFs of heat-treated 70Mn steel samples, but increased friction of the non-heat-treated samples.

Originality/value
This study provides valuable insights into enhancing the mechanical properties and tribological characteristics of 70Mn steel, particularly in the automotive, heavy machinery and high-load application sectors. These industries have stringent requirements for durability and friction control, and the findings of this research are expected to effectively extend the lifespan of mechanical components.

Published: February 2025

PurposeThis paper aims to study whether rural collective construction land marketization (RCCLM) affects pension industry and analyze its impact mechanism.Design/methodology/approachBased on the theory of planned behavior (TPB) and social cognition theory (SCT), this paper constructs a theoretical framework for the purchase behavior of rural retirement housing with the influence of RCCLM. A mixed-methods investigation combining qualitative and quantitative study is adopted in this paper.FindingsThe research results indicate that the purchase intention of rural retirement housing has a significant positive impact on the purchase behavior. However, RCCLM has a significant negative impact on the purchase intention of rural retirement housing. A logical framework of “land system participant behavior” has been constructed from three main bodies: government, developers and elderly urban and rural residents.Practical implicationsThis paper provides suggestions for the three entities from the perspectives of macro, medium and micro-level to improve transaction system for rural collective construction land use right (TSRCCLUR), providing references for the collective construction land marketization policy and the development of the pension industry.Originality/valueThis paper deepens the study of behavior intention in planned behavior, enriches TPB model in the study of rural retirement housing security and clarifies the influence mechanism of the rural retirement housing purchase intention with the theoretical and empirical test of the model.

Published: February 2025

Purpose
The concept of a “sustainable career” has gained significant attention in recent academic literature, extending beyond mere professional success, encompassing elements of happiness, health, productivity and social empowerment. This study aims to develop and validate the sustainable career scale (SCS) to measure this multidimensional construct, including the innovative dimension of “social empowerment,” which emphasizes the importance of responsibly addressing global needs and challenges.

Design/methodology/approach
The research comprises five studies with distinct objectives: Study 1 focuses on item development and latent structure verification; Study 2 confirms the factorial structure; Study 3 assesses concurrent and discriminant validity; Study 4 examines predictive validity and reliability; and Study 5 measures gender invariance.

Findings
Results demonstrate the validity and reliability of the SCS items and structure. Concurrent and discriminant validity are supported by analyzing relationships with work engagement, meaning, employability, burnout, decent work and job satisfaction. Additionally, the scale shows reliability and predictive validity in forecasting eudaimonic, hedonic and social well-being. Gender invariance is confirmed.

Research limitations/implications
Future research could explore its applicability across diverse contexts. The SCS has significant implications for researchers and practitioners, serving as an assessment tool to advance research in sustainable career development and guide interventions to improve careers that address global needs and foster responsible management practices.

Originality/value
The SCS stands out as the first measure to integrate a truly sustainable perspective, encompassing societal and global contexts within the framework of career sustainability. The findings enhance the understanding of sustainable careers and demonstrate the empirical robustness of the SCS.
