AbstractMemory encodes past experiences, thereby enabling future plans. The basolateral amygdala (BLA) is a center of salience networks that underlie emotional experience and thus plays a key role in long-term fear memory formation1, 2. Here we used spatial and single-cell transcriptomics to illuminate the cellular and molecular architecture of the role of the basolateral amygdala in long-term memory. We identified transcriptional signatures in subpopulations of neurons and astrocytes that were memory-specific and persisted for weeks. These transcriptional signatures implicate neuropeptide signaling, mitogen-activated protein kinase (MAPK), brain-derived neurotrophic factor (BDNF), cAMP response element-binding protein (CREB), ubiquitination pathways, and synaptic connectivity in long-term memory. We also discovered that a neuronal sub-population, defined by increasedPenkexpression and decreasedTacexpression, constitutes the most prominent component of the BLA’s memory engram. These transcriptional changes were observed both with single-cell RNAseq and with single-molecule spatial transcriptomics in intact slices, thereby providing a rich spatial map of a memory engram. The spatial data enabled us to show that this neuronal subpopulation further interacts with spatially related astrocytes that are essential for memory consolidation, indicating that neurons require interactions with astrocytes to encode long term memory.

PurposeThis study explored the relationship between employees' cognitive capabilities and firm performance by exploring the moderating role of decision-making style and the mediating effect of knowledge creation. Understanding the role of cognitive capabilities in value creation is crucial for human resource management to achieve the anticipated organizational performance.Design/methodology/approachStructural equation modeling, cognitive skills theory, cognitive skills acquisition theory and a knowledge creation framework were applied.FindingsThe first finding suggests that only A-shaped skills predict higher knowledge creation, while T-shaped skills do not. Second, knowledge creation predicts higher financial performance and a lower level of financial uncertainty. Third, T-shaped skills have no indirect effect on financial performance or financial uncertainty. Fourth, A-shaped skills exerted significant indirect effects on financial performance and uncertainty. Fifth, the rational decision-making style did not moderate the link between knowledge creation and financial performance, as opposed to the intuitive decision-making style.Originality/valueA review of existing research indicates a lack of studies examining the effect of cognitive skills on organizational outcomes and contingencies under which cognitive skills lead to superior outcomes. This study advances research on T-shaped and A-shaped skills and knowledge creation by empirically exploring their interrelationships with financial performance. Managerial implications and suggestions for future research are also highlighted.
Does family ownership matter? Evidence of the payment method and market reaction to M&A deals in Taiwan
Authors: Ahmed Yousry , Elsayed Mohamed , Chen Yuru 
Published: March 2023

Purpose
This paper aims to examine the effect of family ownership on the payment method of mergers and acquisitions (M&A) deals. It also investigates the market reaction around the announcement of these M&A deals.

Design/methodology/approach
Archival data of M&A deals of a sample of Taiwanese listed firms during 2008–2018 are collected and examined using probit, event study and OLS models. This study addresses the endogeneity concern using the two-stage least squares statistical technique and Heckman’s two-step estimation method.

Findings
This study finds that family firms are more likely to use cash as an exchange medium in M&A deals to avoid the problem of diluting control rights. This study further finds that family firms receive a positive market reaction around the announcement of M&A deals relative to non-family counterparts. The empirical results support the notion that family ownership is a value-creation structure.

Practical implications
The findings provide additional evidence-based insights into the debate about family ownership with the aim of informing policy and offering practical recommendations to expand the US-based literature.

Originality/value
To the best of the authors’ knowledge, this is the first study to provide empirical evidence on the impact of family ownership on payment method choice in M&A activities in Taiwan. It also provides novel evidence that family firms experience value gains when taking M&A investment decisions relative to non-family firms.
Tensioning as intertwining, competition and superseding: a self-regulation approach to managing hybridity tensions in social enterprises
Authors: Angelucci Anaïs , Hermans Julie , Radu-Lefebvre Miruna , Angel Vincent 
Published: March 2023

PurposeAs hybrid organisations operating at the intersection of opposing institutional logics, social enterprises (SEs) pursue the creation of social value w hile functioning as businesses, which generates tensions between social and business concerns. Limited knowledge exists, however, of how hybridity is managed at the intra-individual level. Drawing on regulatory focus theory (RFT), this paper investigates the role of self-regulation in managing hybridity tensions in SEs.Design/methodology/approachA multiple-case design is useful in investigating the situated cognitive mechanisms underlying individual self-regulation in the context of managing tensions in SEs. The authors interviewed 22 managers from Belgian SEs that had been active in the home-care sector for at least five years before the COVID-19 pandemic to understand how managers handle the tensions between social and business concerns through self-regulation.FindingsThe authors show that managers in SEs experience three forms of tensioning: tensioning as intertwining, tensioning as competition and tensioning as superseding. Managers respond differently to tensions depending on their self-regulatory focus (promotion versus prevention) on social and business goals, and this is reflected in their hybridity practices (entrepreneurship, commercialisation, corporatisation and managerialisation). Informed by both social and business logics, hybridity practices serve as tactics used as part of managers' self-regulation, enabling them to handle tensions.Originality/valueBy studying the interactions between individual cognition and institutional logics, this study contributes to the micro-foundations of institutional logics by revealing the role of self-regulation mechanisms in managing tensions in hybrid organisations.
Impacts of service guarantees on consumers' perceived quality and satisfaction in e-commerce

Published: March 2023

PurposeE-commerce platforms offer service guarantees (SGs) to improve consumers’ perceived quality and satisfaction. This survey aimed to test the direct and indirect effects of SGs on consumers’ perceived quality and satisfaction concerning the services of an international e-commerce platform.Design/methodology/approachThe survey sample consisted of 378 consumers of an international e-commerce platform. Structural equation modelling (SEM) tested two structural models.FindingsThe first hypothetical model demonstrated that SGs positively and directly affects perceived quality and consumers' satisfaction on an e-commerce platform. This model also revealed that the perceived quality directly and positively impacted consumer satisfaction. The second hypothetical model confirmed that perceived quality mediates the relationship between SGs and satisfaction. Moreover, SGs positively and indirectly impacts consumer satisfaction.Practical implicationsThis study suggests that e-commerce platforms use SGs as a marketing strategy in their business models to increase perceived quality and consumer satisfaction. However, to positively impact the perception of quality and consumer satisfaction, such SGs must have the following characteristics: unconditional, easy to understand and communicate, meaningful, easy and painless to invoke, and easy and quick to collect.Originality/valueThis research demonstrated the direct effects of SGs on perceived quality and consumer satisfaction on an international e-commerce platform. SGs directly impacts consumer satisfaction with the platform, even if they have not experienced its quality attributes (reliability, customisation, security and design). The indirect effects of SGs on consumer satisfaction were also proven, mediated by perceived quality. No previous study demonstrated such relationships simultaneously on e-commerce platforms.

Published: March 2023

PurposeThe purpose of this study is twofold. Firstly, the study has investigated the changing scenario of gender bias in households' education expenditure and the socioeconomic factors responsible for it. Secondly, the study has estimated the inequality in education expenditure for the male and female students and determined the significance of socioeconomic variables in gender discrimination.Design/methodology/approachTo address the above-mentioned issues, this paper has used the unit-level data of NSSO 52nd, 64th, 71st and 75th rounds from 1995–1996 to 2017–2018. The log linear regression model is applied to estimate factor impending average education expenditure dynamics. The Oaxaca–Blinder Decomposition method has been employed to measure gender discrimination, and the Lorenz curve and Gini coefficient are used to assess inequality among girls experiencing prejudice.FindingsThe study has discovered an gender bias in education expenditure against females during the study period in India. Further, it has been found that gender discrimination against girl students is decreasing. Moreover, the factors such as age, religion, castes, MPCE (income quantile), type of institution, present enrolment and type of education are responsible for this gender differences.Originality/valueThis paper uses 20 years of household-level data for study and suggests that discriminatory behaviour of households and credit constraints of the underdeveloped countries prevent investment in girl's education. Therefore, the state must pay for education of girls by offering scholarships and free or heavily subsidized education. In addition to this, awareness programs for gender equality should also be implemented by the government, especially in rural areas.Peer reviewThe peer-review history for this article is available at: https://publons.com/publon/10.1108/IJSE-08-2022-0537.
The influence of the firm on family business branding: the mediator role of the family
Authors: Zhang Zhibiao , Rowan Peter 
Published: March 2023

PurposeIt is acknowledged that the firm and the family interact in the family firm system and that family identity can influence family business brand communication through affecting stakeholders' perception, raising a question of whether the firm can implement its effect on the communication of family business brands via family identity. To address this question, this research investigates how firm revenue influences family business branding via family harmony.Design/methodology/approachData for this research were gathered from a survey of 327 Chinese family firms.FindingsThe results show that family harmony fully mediates the relationship between firm revenue and family business branding.Originality/valueThis study is the first to demonstrate that the firm has an indirect effect on family business branding via family identity, a contribution to family business brand literature. The findings also offer insights into the relationship between firm performance and family business branding. Additionally, this project has implications for research on family harmony in the family business.
Why do consumers purchase green clothing? Investigating symbolic meanings beyond social status and the role of consumer mindset
Authors: Bakış Selen , Kitapçı Hakan 
Published: March 2023

PurposeIn the purchase intention of green products context, researchers have mainly investigated the role of symbolism but have mostly discussed symbolic attributes/meanings in terms of social status only. This research aims to investigate the impact of four perceived symbolic meanings of green clothing (status, environmentalism, innovation and fashion symbols) on consumers' purchase intention of green clothing through their attitude toward it. Besides, the moderating role of a consumer mindset in the indirect relationship between symbolic attributes and the purchase intention of green products through consumer attitude is examined.Design/methodology/approachThe data were collected through a survey from a sample of 325 respondents in Turkey, especially younger ones. The data were analyzed via confirmatory factor analysis and hypothesized relationships were tested with multiple and simple regression analyses and PROCESS macros in SPSS.FindingsAll symbolic meanings of green clothing impact purchase intention positively and indirectly through consumers' attitudes toward it. The results of moderated mediation analyses showed that the impact of symbolic meanings, except for environmentalism symbol, on purchase intention through consumer attitude was significantly moderated by the consumer mindset.Originality/valueThis research contributes to the under-researched areas of the impact of various symbolic attributes/meanings of green clothing on consumers' purchase intention. Besides, this study advances the role of consumer mindset in consumer behavior research in such a way that it connects mindsets of personality, consumers' attitudes toward green products and their green purchase intention. Furthermore, this study addresses the gap in regard to the role of mindsets of personality on sustainable/environmental behaviors. It will provide implications for fashion marketing managers to develop appropriate targeting, positioning and communication strategies for consumers' mindsets.
2D seismic design on frontier basins using potential field data, a case study in the south of the eastern arm of the East African Rift System
Authors: Nalogwa Mussa , Schultz Gehrig , Laws Kevin , Thompson Richard 
Published: March 2023

AbstractThe 2D seismic design for a frontier basin was conducted from potential field data and available geological information using a case of a Block within the East African Rift System. The Block forms part of a southern extension of the eastern branch of the East African Rift System. The most significant structural features of the Block within this part of the rift were mapped using Airborne Gravity Gradiometry data along A, B and C sub‐basin boundaries. The Block covers a total area of more than 10,107 km2 in the central north of Tanzania. The 2D seismic lines were planned to intersect the major structures within the Block, in which a total of 1074 line kilometres from 18 seismic lines were proposed. The spatial sampling interval of 12.5 m with a minimum of two samples per wavelength was deemed adequate for a frontier basin, as would record dips well above 15° limit from the minimum target of 2000 m. The relevant source spacing may be suitable if tested, and the required energy has been recorded. These parameters, though may need refining depending on the field, are proposed for a good resolution imaging and wide bandwidth recording of complex geology for a frontier basin. The seismic design provided the basis for the economic evaluation of the possible survey to be undertaken for a frontier basin. The suggested parameters allow for the flexibility of inclusion or improvement in any subsequent study related to the seismic acquisition in a Block with similar characteristics.
Benign effects of logging on aerial insectivorous bats in Southeast Asia revealed by remote sensing technologies

Published: March 2023

Abstract

Logging is the most widespread disturbance in tropical forests, altering ecological communities and functions. However, many species can persist in logged forests, particularly where disturbance is low. Despite a growing understanding of how logging affects wildlife, there remains little information for Southeast Asia's bats—in part due to major challenges in monitoring.

We integrated remote sensing data from passive acoustic bat detectors with LiDAR‐derived measures of forest structure from a human‐modified landscape in Sabah, Borneo. Our appraisal of logging effects benefitted from a semi‐automated classifier of bat calls that vastly speeds up the analysis of acoustic recording data. We recorded 105,576 bat passes from 21 phonic groups across a habitat disturbance gradient, comprising old‐growth forest, repeatedly logged forest and tree plantations.

We show that logging pressure (as depicted by changes to habitat quality, e.g. canopy height or shape) had negligible impact on the acoustic activity of bats. However, bat activity was higher in areas with a greater extent of high‐biomass forest, as well as areas with greater topographical ruggedness. Logged forest supported higher levels of activity for several common bat phonic groups compared to old‐growth forest. Across the landscape, plantations supported the lowest levels of bat activity, representing a threefold decrease compared to old‐growth forest, and several species were not recorded in this habitat.

We found different call groups demonstrated different responses to forest disturbance. Sheath‐tailed bats (Emballonura spp.) were active across all habitat types and were the most resilient to logging. Edge/open foragers were more prevalent in highly forested and topographically rugged areas. Horseshoe and leaf‐nosed bats (flutter clutter foragers) demonstrated idiosyncratic responses to logging but were consistently absent from plantations.

Synthesis and applications. Logged forests can provide an important refuge for many common bat species in Southeast Asia, but do not capture the full breadth of forest‐specialist species. Nevertheless, logged forests provide substantially better habitat for bats than tree plantations. While aerial insectivorous bats sampled via acoustic methods are poor indicators of forest disturbance overall, several species that respond predictably to logging could be targeted for biodiversity monitoring using acoustic and capture‐based methods.
Fragmentation disrupts microbial effects on native plant community productivity
Authors: Kiesewetter Kasey N. , Otano Leydiana , Afkhami Michelle E. 
Published: March 2023

Abstract

Anthropogenic habitat fragmentation—the breaking up of natural landscapes—is a pervasive threat to biodiversity and ecosystem function world‐wide. Fragmentation results in a mosaic of remnant native habitat patches embedded in human‐modified habitat known as the ‘matrix’. By introducing novel environmental conditions in matrix habitats and reducing connectivity of native habitats, fragmentation can dramatically change how organisms experience their environment. The effects of fragmentation can be especially important in urban landscapes, which are expanding across the globe. Despite this surging threat and the importance of microbiomes for ecosystem services, we know very little about how fragmentation affects microbiomes and even less about their consequences for plant–microbe interactions in urban landscapes.

By combining field surveys, microbiome sequencing and experimental mesocosms, we (1) investigated how microbial community diversity, composition and functional profiles differed between 15 native pine rockland fragments and the adjacent urban matrix habitat, (2) identified habitat attributes that explained significant variation in microbial diversity of native core habitat compared to urban matrix and (3) tested how changes in urbanized and low connectivity microbiomes affected plant community productivity.

We found urban and native microbiomes differed substantively in diversity, composition and functional profiles, including symbiotic fungi decreasing 81% and pathogens increasing 327% in the urban matrix compared to native habitat. Furthermore, fungal diversity rapidly declined as native habitats became increasingly isolated, with ~50% of variation across the landscape explained by habitat connectivity alone. Interestingly, microbiomes from native habitats increased plant productivity by ~300% while urban matrix microbiomes had no effect, suggesting that urbanization may decouple beneficial plant–microbe interactions. In addition, microbial diversity within native habitats explained significant variation in plant community productivity, with higher productivity linked to more diverse microbiomes from more connected, larger fragments.

Synthesis. Taken together, our study not only documents significant changes in microbial diversity, composition and functions in the urban matrix, but also supports that two aspects of habitat fragmentation—the introduction of a novel urban matrix and reduced habitat connectivity—disrupt microbial effects on plant community productivity, highlighting preservation of native microbiomes as critical for productivity in remnant fragments.
Evolution and Spread of Politeness Systems inIndo‐European
Authors: Dunn Michael , Bellamy Kate 
Published: March 2023

AbstractIn this paper, we investigate the phenomenon of pronominal politeness in the Indo‐European languages and demonstrate that the processes of change of pronominal systems related to politeness follow two evolutionary regimes, one inside the ‘Standard Average European’ (SAE) linguistic area and another outside of it. Historical processes of language change differ at different levels of linguistic structure. In general, we presume that lower level, unconscious aspects of language change slowly over phylogenetic time, giving rise to patterns of relationship that can often be described as a family tree. Aspects of language that are consciously manipulated by speakers are expected to vary at a faster rate and to diffuse within areas of contact. Politeness is a social phenomenon, so we expect these systems to be highly susceptible to areal norms of interaction. We show that the similarities of SAE politeness systems can be accounted for with a model of convergence due to parallel evolution in a shared (social‐demographic) environment, rather than by genealogical relatedness or borrowing. By quantifying and testing factors determining rates of structural change, we offer a novel and realistic approach that can explain similarities between distantly related languages sharing the same environment.
