Published: November 2023

AbstractIntroductionThis study investigated whether behavioral problems in children were associated with fractional anisotropy (FA) of white matter tracts connecting from other brain regions to right and left frontal lobes. We considered internalizing and externalizing behavioral problems separately and contrasted patterns of associations in children born at term and very preterm.MethodsParents completed the Child Behavior Checklist/6-18 questionnaire to quantify behavioral problems when their children were age 8 years (N=36 FT and 37 PT). Diffusion magnetic resonance scans were collected at the same age and analyzed using probabilistic tractography. We used multiple linear regression to investigate the strength of association between age-adjusted T-scores of internalizing and externalizing problems and mean fractional anisotropy (mean-FA) of right and left uncinate, arcuate, and anterior thalamic radiations, controlling for birth group and sex.ResultsRegression models predicting internalizing T-scores from mean-FA found significant group-by-tract interactions for the left and right arcuate and right uncinate. Internalizing scores were negatively associated with mean-FA of left and right arcuate only in children born at term (pleftAF=0.01,prightAF=0.01). Regression models predicting externalizing T-scores from mean-FA found significant group-by-tract interactions for the left arcuate and right uncinate. Externalizing scores were negatively associated with mean-FA of right uncinate in children born at term (prightUF=0.01) and positively associated in children born preterm (prightUFpreterm=0.01). Other models were not significant.ConclusionsIn this sample of children with scores for behavioral problems across the full range, internalizing and externalizing behavioral problems were negatively associated with mean-FA of white matter tracts connecting to frontal lobes in children born at term; externalizing behavioral problems were positively associated with mean-FA of the right uncinate in children born preterm. The different associations by birth group suggest that the neurobiology of behavioral problems differs in the two birth groups.’Highlights’⍰ Internalizing problems were negatively associated with arcuate FA in term children.Externalizing problems negatively associated with right uncinate FA in term children.Externalizing problems were positively associated with right uncinate FA in preterm.

ABSTRACTThe shrimp industry has historically been affected by viral and bacterial diseases. One of the most recent emerging diseases is the Acute Hepatopancreatic Necrosis Disease (AHPND), which causes severe mortality. Despite its significance to both sanitation and economics, little is known about the molecular response of shrimp to this disease. Here, we present the cellular and transcriptomic responses ofLitopenaeus vannameiexposed to twoVibrio parahaemolyticusstrains for 98h, wherein one is non-pathogenic (VpN) and the other causes AHPND (VpP). Exposure to VpN strain resulted in minor alterations in hepatopancreas morphology, including reductions in the size of R and B cells as well as detachments of small epithelial cells from 72 h onwards. On the other hand, exposure to VpP strain is characterized by acute detachment of epithelial cell from the hepatopancreatic tubules and infiltration of hemocytes in the inter-tubular spaces. At the end of exposure, RNA-Seq analysis revealed functional enrichment in biological processes, such as thetoll3receptor signaling pathway, apoptotic processes, and production of molecular mediators involved in the inflammatory response of shrimp exposed to VpN treatment. The biological processes identified in the VpP treatment include superoxide anion metabolism, innate immune response, antimicrobial humoral response, andtoll3receptor signaling pathway. Furthermore, KEGG enrichment analysis revealed metabolic pathways associated with survival, cell adhesion, and reactive oxygen species, among others, for shrimp that were exposed to VpP. Our study proves the differential immune responses to two strains ofV. parahaemolyticus,one pathogenic and the other nonpathogenic, enlarges our knowledge on the evolution of AHPND inL. vannamei, and uncovers unique perspectives on establishing genomic resources that may function as a groundwork for detecting probable molecular markers linked to the immune system in shrimp.

ABSTRACTIn our phylogenetic studies of a bacterial strain isolated from anArabidopsissuspension culture, we obtained convincing evidence for contamination of the published 16S rRNA gene sequence ofRothia amaraetype strain J18T(GenBankAY043359.1). Correction of this sequence by deleting the contamination region eliminated contradictions in bioinformatic results that included comparisons of the small-subunit (SSU) rRNA secondary structures. Further, correction of the contaminated sequence yielded sequence identity values for the 16S rRNA genes of the isolate andR. amaraetype strain J18T(and more than a dozen otherR. amaraemembers) above the threshold for species demarcation. The phylogram of the 16S rRNA gene sequences of the type strains closely related to the isolate under study (interspecies sequence identity values, 96–98.7%) united members of the familyMicrococcaceae(the generaRothia, KocuriaandArthrobacter). A great diversity of habitat conditions was noted for these bacteria, isolated from animals, soil, aqueous media, plant tissues and other sources. This applies, in particular, toR. amaraemembers that are most closely related to the isolate under study by the 16S rRNA gene sequence criterion (sequence identity, near 100%) and belong to four ecotypes: Antarctic, aquatic, soil and endophytic.

AbstractProminin-1 (Prom1) is a five-transmembrane-pass integral membrane protein that associates with curved regions of the plasma membrane. Prom1 interacts with membrane cholesterol and actively remodels the plasma membrane. Membrane bending activity is particularly evident in photoreceptors, where Prom1 loss-of-function mutations cause failure of outer segment homeostasis, leading to cone-rod retinal dystrophy (CRRD). The Tweety Homology (Ttyh) protein family has been proposed to be homologous to Prominin, but it is not known whether Ttyh proteins have an analogous membrane-bending function. Here, we characterize the membrane-bending activity of human Prom1 and Ttyh1 in native bilayer membranes. We find that Prom1 and Ttyh1 both induce formation of extracellular vesicles (EVs) in cultured mammalian cells and that the EVs produced are physically similar. Ttyh1 is more abundant in EV membranes than Prom1 and produces EVs with membranes that are more tubulated than Prom1 EVs. We further show that Prom1 interacts more stably with membrane cholesterol than Ttyh1 and that this may contribute to membrane bending inhibition in Prom1 EVs. Intriguingly, a loss-of-function mutation in Prom1 associated with CRRD induces particularly stable cholesterol binding. These experiments provide mechanistic insight into Prominin function in CRRD and suggest that Prom and Ttyh belong to a single family of functionally related membrane-bending, EV-generating proteins.

PurposeExperiencing stigma after abortion may decelerate the accumulation of human capital. Despite the importance of studying the relationship between religiosity and abortion stigma, the topic is understudied, especially in Islamic contexts. Abortion was legalized in Iran in 2005. Under the new law, far more cases are allowed for abortion. This change provided an opportunity to explore the interplay of abortion stigma, legalization and religiosity in Iran.Design/methodology/approachUsing regression analysis based on 291 completed questionnaires from two cities in Iran, this study analyzes the relation between abortion stigma level and religiosity in Iran, controlling for contextual and individual variables. The time trend is also identified. The authors use different manifestations of abortion stigma as dependent variables.FindingsThe authors found that abortion stigma and its two manifestations decreased after the new law, suggesting that its legalization might have caused abortion stigma to decrease gradually. Another finding of this study is that the correlations between abortion stigma (internalized stigma) and individual religiosity level are meaningful and positive; religious people feel higher levels of abortion stigma.Originality/valueThe study supports the idea that effective health regulations (in the specific case of abortion) would result in less cost/risk of social issues like stigma. Policymakers in religious societies must pay more attention to the specific case of abortion stigma since it is very important for the mental health of women who think of abortion and/or select it.

PurposeThis paper aims to analyze the ethical responses of the fashion industry to the first wave of the COVID-19 pandemic when the entire world was shocked by the rapid spread of the virus. The authors describe lessons from emergency ethics of care in the fashion industry during the initial months of COVID-19, which can assist fashion managers in improving ethical decisions in future operations.Design/methodology/approachRapid qualitative research methods were employed by conducting real-time, in-depth interviews with key informants from multinational fashion companies operating in Spain, a severely affected region. A content analysis of news articles published during the first months of 2020 was conducted.FindingsFive critical disruptions in the fashion industry were identified: (1) changes in public needs, (2) transportation and distribution backlogs, (3) defective and counterfeit supplies, (4) stakeholder relationships at stake and (5) managers' coping challenges. Additionally, five business survival responses with a strong ethics of care component were identified, implemented by some fashion companies to mitigate the damage: (1) adapting production for public well-being, (2) enhancing the flexibility of logistic networks, (3) emphasizing quality and innovation, (4) reinventing stakeholder collaborations and (5) practicing responsible leadership.Originality/valueDespite the well-documented controversies surrounding unethical practices within the fashion industry, even during COVID-19, our findings inform managers of the potential and capability of fashion companies to operate more responsibly. The lessons learned can guide fashion companies' operations in a post-pandemic society. Furthermore, they can address other grand challenges, such as natural disasters, geopolitical conflicts and climate change.

Published: November 2023

PurposeBased on self-determination theory (SDT), this paper seeks to identify autonomous motivations driving nostalgia-related cultural tourism among visitors to satisfy their craving to revisit Luxor and re-root their identities. This paper looked at the nexus of destination image and past experience, as well as nostalgic visitors' revisit intention and actual behavior toward Luxor.Design/methodology/approachPartial least squares-structural equation modeling (PLS-SEM) was employed to quantitatively analyze 354 responses from Luxor's visitors, and 17 interview transcripts were narrated using MAXQDA software.FindingsAutonomous motivations influenced revisit intentions significantly, and revisit intentions acted as a strong mediator between actual visit behavior and autonomous motivations.Practical implicationsDestination marketers need to create nostalgic emotional bonds with people and destinations by planning cultural events that leave visitors with unforgettable memories of these particular moments. They also need to focus more on promotional strategies, develop messages with words that have emotional meaning and highlight crucial characteristics that tourists can quickly identify when visiting a destination.Originality/valueCultural tourism has emerged as a dominant niche sector worldwide; nevertheless, nostalgia-related cultural tourism has received less attention. As a result, the primary purpose of this paper is to provide a methodological framework for nostalgia tourism promotion in Luxor, Egypt. Luxor was chosen and has been an excellent subject for this paper, which can further evoke a sense of nostalgia. Hence, this paper prioritizes cultural site preservation and promotion.

Published: November 2023

PurposeThe purpose of this article is to address research gaps relating to agency and institutionalism in new institutional theory (NIT) and institutional work (IW) and use the critical sensemaking (CSM) approach to bridge the debates around agency, especially on issues of language and discourse, actor network theory (ANT) and history.Design/methodology/approachA conceptual analysis of the literature is performed to discuss issues of agency in IW and CSM in organizations, and examples of empirical studies are used to illustrate connectivity, contrast and fusion.FindingsThe analysis illustrates points of distance (rather than disconnect), but most importantly, connectivity and the potential for further developments between the literature on IW and CSM.Social implicationsDiscussion around new possibilities to focus on agency has the potential to contribute to humanist thinking about the (agentic) character of organizations and the potential for social change.Originality/valueThe article contributes to the discussion of agency in the organization through a starting point (i.e. CSM) outside of NIT.
Competency, guanxi and growth aspirations: small tourism enterprises in dynamic environments
Authors: Liu Xiaotong , Wen Tong , Qin Cen 
Published: November 2023

PurposeThis paper aims to explore how typical personal, interpersonal and environmental factors influence entrepreneurs' growth aspirations by investigating the impact mechanism of entrepreneurial competency and guanxi on the growth aspirations of small tourism entrepreneurs in a dynamic environment.Design/methodology/approachApplying social cognitive theory (SCT) and business growth theory (BGT), this research uses confirmatory factor analysis and structural equation modeling (SEM) based on the questionnaire survey data of 371 small tourism business owners/owner-managers to test the relationship between entrepreneurial competency, guanxi and growth aspirations, with self-efficacy as a mediator and environment dynamism as a moderator.FindingsThe findings indicate that entrepreneurial competency is a more direct and significant factor than guanxi in facilitating the entrepreneurial growth aspirations in small tourism enterprises (STEs). Entrepreneurial competency and guanxi can both enhance entrepreneurs' self-efficacy, which then affects their aspirations to grow their business. Self-efficacy is a critical predictor of entrepreneurs' growth aspirations in STEs, although its effect is weakened by environmental dynamism.Originality/valueThis study expands the integrated application of SCT and BGT in tourism context, providing a more comprehensive and nuanced interpretation of the growth aspirations of entrepreneurs in STEs. It sheds more light on the effect of different entrepreneurial capital on growth aspirations and provides managerial implications accordingly.
Private brand introduction and selling mode decision when considering risk aversion
Authors: Lyu Lubing , Zhao Haixia 
Published: November 2023

PurposeThis paper aims to study the interplay between a risk-averse national brand manufacturer's (NBM) selling mode decision and a risk-neutral e-platform's private brand (PB) introduction decision.Design/methodology/approachA game theory model is used to solve selling mode decision, that is whether transform the selling mode from the wholesale mode to the marketplace mode, and PB introduction decision, that is, whether introduce the PB.FindingsThe results show that for the NBM, under certain condition, the NBM's selling mode decision is not affected by the e-platform's PB introduction decision. High revenue-sharing rate is conducive only when the difference in consumer preference between the PB and the national brand (NB) is small. The NBM's risk aversion will improve the applicability of the marketplace mode. For the e-platform, high PB preference of consumers and risk-averse behavior of the NBM is not conducive to PB introduction. For the supply chain, scenarios that the NB monopolizes the market under the wholesale mode and PB introduction under the marketplace mode should be prevented. PB introduction under the wholesale mode will become the only equilibrium with the increase of risk aversion of the NBM. Finally, the authors extend the scenario that consumers prefer the PB and the e-platform is risk-averse enterprise and find that PB introduction under the wholesale mode is detrimental to the NBM but beneficial to the supply chain. The impact of consumers' PB preference on the e-platform's PB introduction is opposite to the basic model. The impact of the e-platform's risk aversion on game equilibrium is opposite to that of the NBM's risk aversion.Originality/valueThis paper is first to study selling mode decision and PB introduction decision when considering enterprises' risk-averse attitude.
How managers' perceptions about dynamic complexity change: sensemaking catalyzed by shock and surprise
Authors: Langley Paul , Rieple Alison 
Published: November 2023

PurposeThis empirical study uncovers emotional sensemaking factors that cause changes in management perceptions about wicked strategic problems under dynamic complexity. These perception changes improve understanding of, and solutions to, the wicked problem.Design/methodology/approachSenior managers from three large organizations in different sectors participated in gaming simulation workshops. The strategic issues at stake were intractable and divisive. Qualitative methods captured participants' perceptions of the problems and the dynamic complexity that they faced and how they changed.FindingsFlawed management perceptions were revised as sensemaking processes were catalyzed by emotions of shock/surprise that came from experiencing unexpected stakeholder conduct within a simulation. The plausibility of the conduct was strengthened because managers were role-playing stakeholders. The shock/surprise emotion uncoupled attachment to entrenched beliefs, leading to a willingness to revise the flawed perceptions. The changed perceptions created new insights for a solution to the wicked problem.Practical implicationsPractical implications are how management practitioners can improve the tackling of wicked strategic problems through the use of shock and surprise in a gaming simulation.Originality/valueThis research extends theory on the role of emotions in sensemaking under dynamic complexity. The authors uncover how a hierarchy of managers' emotions used in sensemaking explains the catalytic effect of the shock and surprise of unexpected stakeholder conduct on revisions to their perceptions of the outcomes of the dynamic complexity.

Published: November 2023

AbstractGut microbiomes are diverse ecosystems whose drivers of variation remain largely unknown, especially in time and space. We analysed a dataset with over 900 red squirrel (Tamiasciurus hudsonicus) gut microbiome samples to identify the drivers of gut microbiome composition in this territorial rodent. The large‐scale spatiotemporal replication in the data analysed was an essential component of understanding the assembly of these microbial communities. We identified that the spatial location of the sampled squirrels in their local environment is a key contributor to gut microbial community composition. The non‐core gut microbiome (present in less than 75% of gut microbiome samples) had highly localised spatial patterns throughout different seasons and different study areas in the host squirrel population. The core gut microbiome, on the other hand, showed some spatial patterns, though fewer than in the non‐core gut microbiome. Environmental transmission of microbiota is the likely contributor to the spatiotemporal distribution observed in the North American red squirrel gut microbiome.
The effect of signaling on crowdfunding performance on social economy organizations in South Korea
Authors: Lee Sun Hee , Lee Sang‐Youn 
Published: November 2023

AbstractCrowdfunding is an innovative means of financing entrepreneurial initiatives. This study explores the effect of signaling on the crowdfunding performance of social economy organizations (SEOs) in South Korea. Analyzing 677 reward‐based crowdfunding projects by SEOs, we found that signaling social purpose, economic purpose, and organizational information were likely to be related to performance. In addition, signals reflecting an isomorphism akin to that of SEOs' identity were also positively correlated with crowdfunding performance. These findings contribute to the literature by offering insights about the effect of signals of SEOs on crowdfunding and demonstrating that fundraiser characteristics may influence crowdfunding performance.

Published: November 2023

AbstractAcute cholecystitis, a very common disease, is usually caused by gallstone obstruction of the cystic duct. Meanwhile, strangulated cholecystitis is extremely rare, and it develops when the gallbladder is strangled by a band. It is very similar to gallbladder torsion in terms of imaging findings and obstruction of blood and biliary flow, and it requires emergency surgery. We herein report a case of a 90‐year‐old woman with gallbladder strangulation caused by a fibrotic band due to a chlamydia infection, and we also reviewed some literature on strangulated cholecystitis.
