AbstractThe increasing use of artificial light at night (ALAN) is currently a major anthropogenic disturbance, with largely unappreciated eco-evolutionary consequences for nocturnal but also diurnal organisms. It has been hypothesized that light pollution could create new opportunities for the latter to forage and reproduce at night, which is called the ‘night-light’ niche, with fitness consequences still scarcely explored.We exposed diurnal parasitoid wasps (Venturia canescens) to one of three light-at-night conditions: control (0 lux), low intensity (0.7 lux) or high intensity (20 lux) throughout their lives. We then monitored changes in both behavioural and life-history traits, namely daytime and nighttime feeding and egg-laying activity, reproductive senescence, lifespan and lifetime reproductive success.Light pollution influenced the nighttime activity of wasps. The proportion of wasps feeding and laying eggs at night increased, and we also detected a tendency for a higher nighttime reproductive success under a high intensity of light pollution. Surprisingly, high intensity of light pollution also increased the wasps’ lifespan. Such changes did not affect the lifetime reproductive success of the wasps, but influenced the distribution of ovipositions between day and night.Reproductive senescence occurs inV. canescens, evidenced by the linear decline in daily reproductive success with age regardless of the light condition. ALAN conditions, in interaction with mother age, affected developmental time in offspring, highlighting an effect on reproductive senescence.We demonstrated that light pollution induced the use of the ‘night-light’ niche in a diurnal insect, with a shift in the distribution of egg-laying events between day and night. While we did not observe strong consequences on individual fitness, such changes in the dynamics of parasitism behaviour may nevertheless have major consequences for population dynamics, especially in natural conditions.

AbstractVisual object recognition is a dynamic process by which we rapidly extract meaningful information about the things we see. However, the functional relevance of inter-regional feedforward and feedback signals in the human ventral visual pathway remain largely unspecified, while its unclear whether computational models of vision alone can accurately capture object-specific representations. Here, we probe these dynamics using a combination of representational similarity and connectivity analyses of fMRI and MEG data recorded during the recognition of familiar, unambiguous objects. Modelling the visual and semantic properties of our stimuli using an artificial neural network as well as a semantic feature model, we find that unique aspects of the neural architecture and connectivity dynamics relate to visual and semantic object properties. Critically, we show that recurrent processing between anterior and posterior ventral temporal cortex relates to higher-level visual properties prior to semantic object properties, in addition to semantic-related feedback from the frontal lobe to the ventral temporal lobe between 250 and 500ms after stimulus onset. These results demonstrate the distinct contributions made by semantic object properties in explaining neural activity and connectivity, highlighting it as a core part of object recognition not fully accounted for by biologically inspired neural networks.

AbstractGynoecium polarity establishment is regulated by auxin, a phytohormone whose signal is transduced through several pathways. The relationship between the ETT and canonical TIR1/AFB pathways, and their relevance for carpel development beyondArabidopsis thaliana, have not been investigated. The data presented here show that the expression patterns of canonical and ETT-mediated signalling components, and phenotypes of higher order mutants are shared betweenArabidopsisandCapsella rubella.tir1 afb2 ettmutants partially phenocopyett arf4double mutants, suggesting a role for AUXIN RESPONSE FACTOR 4 (ARF4) in the integration of canonical and ETT-mediated signalling. Comparative transcriptomics revealed that the auxin-independent mis-regulation ofYABBYgenes correlate with patterning defects observed inArabidopsis ett arf4mutants. Together, the data presented suggest conserved synergism between canonical and ETT-mediated pathways in gynoecium polarity establishment in theBrassicaceae. Finally, the data suggest that ETT/ARF4 function to prevent the auxin-induced expression of a range of targets inArabidopsis, consistent with activator-repressor ARF antagonism, and implying that the maintenance of auxin insensitivity by repressive ARFs is important for a range of biological processes.Summary StatementHere the relationship between canonical and ETT-mediated auxin signalling machineries is investigated inArabidopsisandCapsellarevealing conserved synergism between these two pathways inBrassicaceaewith distinct fruit shapes.
Reward-based improvements in motor sequence learning are differentially affected by dopamine
Authors: Sporn Sebastian , Galea Joseph M 
Published: March 2023

AbstractReward is a powerful tool to enhance human motor behaviour with research showing that it promotes motor sequence learning through increases in both motor vigour and movement fusion. Specifically, during a sequential reaching movement, monetary incentive leads to increased speed of each movement (vigour effect), whilst reward-based performance feedback increases speed of transition between movements (fusion effect). Therefore, motor sequence learning can be driven by distinct reward types with dissociable underlying processes. The neurotransmitter dopamine has been implicated to modulate motor vigour and regulate movement fusion. However, in humans, it is unclear if the same dopaminergic mechanism underlies both processes. To address this, we used a complex sequential reaching task in which rewards were based on movement times (MT). Crucially, MTs could be reduced via : 1) enhanced speed of individual movements (vigour effect) and/or 2) enhanced speed of transition between movements (fusion effect). 92 participants were randomly assigned to a reward and no reward group and were given either 2.5mg of the dopamine antagonist haloperidol or a placebo. Our results demonstrate that haloperidol impaired the reward-based effects on motor vigour whilst not affecting movement fusion. Thus, we illustrate that whilst both strategies are reward sensitive, they rely on dissociable mechanisms.

AbstractBACKGROUNDAlzheimer’s Disease (AD) is a complex clinical phenotype with unprecedented social and economic tolls in an aging global population. Real World Data (RWD) from electronic health records (EHRs) offer opportunities to accelerate precision drug development and scale epidemiological research on AD. A precise characterization of AD cohorts is needed to address the noise abundant in RWD.METHODSWe conducted a retrospective cohort study to develop and test computational models for AD cohort identification using clinical data from 8 Massachusetts healthcare systems. We mined temporal representations from EHR data using a novel transitive sequential pattern mining algorithm (tSPM) to train and validate our models. We then tested our models against a held-out test set from a review of medical records to adjudicate the presence of AD. We trained two classes of models using Gradient Boosting Machine (GBM) to compare the utility of AD diagnosis records versus the tSPM temporal representations (comprising sequences of diagnosis and medication observations) from electronic medical records for characterizing AD cohorts.RESULTSIn a group of 4,985 patients, we identified 219 sequences of medication-diagnosis records for constructing the best classification models. The models with the sequential features improved AD classification by a magnitude of up to 16 percent (over the use of AD diagnosis codes). Six groups of sequences, which we refer to as temporal digital markers, were identified for characterizing the AD cohorts, including sequences that involved (1) a symptom or (2) a risk factor in the past, followed by an AD diagnosis, (3) AD medications, (4) indirect risk factors, symptom management, and potential side effects, (5) comorbidities with possible shared roots or side effects, and (6) plural encounters with of AD diagnosis codes. Discussions of how the identified sequential patterns can be interpreted are provided.CONCLUSIONSWe present sequential patterns of diagnosis and medication codes from electronic medical records, as digital markers of Alzheimer’s Disease. Classification algorithms developed on the sequential patterns can replace standard features from EHRs to enrich phenotype modeling.
Development of membrane-like pre-stem cells after released from tube-shaped niches
Authors: Kong Wuyi , Han XiuJuan , Zhu XiaoPing , Wang Hong 
Published: March 2023

AbstractWe previously identified three distinct pre-stem cell lineages that further develop into blood CD34-positive stem cells, and mesenchymal stem cells. The pre-CD34-positive stem cells are spore-like, while the pre-mesenchymal stem cells are fusiform-shaped. All of them originate or released from tube-shaped tissue structures, or niches. In the current study, we present two membrane-like pre-stem progenitors. One of them had red thin membrane structures that were from disconnection of bamboo-like tissues and developed into thin membrane-like multi-nucleated cells. The other membrane-like structure had geometric-shape and was the place of developing numerous c-kit-positive stem cell progenitors. One geometric-shaped membrane could produce dozens to hundreds of progenitors in a synchronized pattern. Our findings provide more evidence that postnatal stem cells are unipotent and self-renewed in sealed tube-shaped structures. The tube-shaped structures released their inclusions that have distinct morphological differences among the cellular lineages. Thus, the self-renewal of each lineage-distinct stem cell has its unique pattern. Further, our data suggests that postnatal stem cells are renewed via a recurrent pattern. Our findings again challenged the old concepts of stem cell niche components, the origins of stem cell lineages and the self-renewal of stem cells.

Authors: Hossain Dewan Mahboob , Alam Md. Saiful 
Published: March 2023

PurposeThe main objective of this article is to explore the discourses on social inequality in the annual reports of Bangladeshi NGOs.Design/methodology/approachTo fulfil this objective, a discourse analysis was conducted on the latest annual reports of ten renowned NGOs in Bangladesh. The findings were interpreted from the impression management perspective.FindingsIt was found that the NGOs of Bangladesh are highlighting several social inequality issues such as poverty, gender inequality, inequality related to getting healthcare, legal and education facilities, etc. in their annual reports. Several impression management tactics were applied in the narratives of the annual reports. The NGOs portrayed themselves as “problem solvers” who are the saviors of distressed people.Practical implicationsThis study will facilitate improving the understanding of NGO communication. Policymakers will be able to understand the disclosures of NGOs and consider the necessity to provide guidance that may lead to better information dissemination through reports.Originality/valueThis study will contribute to the limited literature on NGO disclosures from the context of developing economies. In the context of NGO, this research is methodologically novel as it applies discourse analysis and interprets the findings through the lens of impression management.
Family ownership and capital structure: evidence from ASEAN countries
Authors: Tran Trang Khanh , Nguyen Lan Thi Mai 
Published: March 2023

PurposeThis paper examines the capital structure decisions of family firms in Southeast Asian (ASEAN) countries, considering the moderating effects of various firm-level and country-level factors.Design/methodology/approachThe authors apply various panel data models to analyze the data of listed firms in six ASEAN countries over the period of 2007–2017.FindingsThe authors find that family firms tend to use more debt, particularly short-term debt, than non-family firms, which is explained by family owners' concern about the risk of losing control. The authors further document that family firms would use more debt when they have lower ownership concentration, have more family members on the board of directors and are young firms. The authors also find that the impact of family ownership on capital structure is moderated by the level of investors' legal protection of a country.Originality/valueThis study, for the first time, provides comprehensive analyses of the financing decisions of family firms in ASEAN using a unique hand-collected dataset, which highlights that regional culture and market conditions can shape family firms' financing decisions. The authors also manage to mitigate the endogeneity issues that pervade most research on family firms. In addition, this research further explores the heterogeneous impacts of family control on capital structure given different levels of board involvement, firm age, ownership concentration, and most importantly, institutional differences. Such insights provide useful information for prospective investors as well as regulators to make more efficient investment and legislative decisions.

Published: March 2023

PurposeIn the current period quality assurance (QA) and technical vocational education and training (TVET) are known as the two comprehensively examined ideas in schooling, dependent on exceptional abilities in this modern era of Industrial Revolution (IR) 4.0. The incapability or need for QA of technology-oriented programs has been dissected by policy makers as a hindrance in accomplishing the TVET objectives. Consequently, the reason for this exploration paper was to contemplate over the impact and association of QA on TVET programs and level of preparedness of TVET teachers for the market of IR 4.0 in Pakistan.Design/methodology/approachIn this study a quantitative research method with survey-based research has been used whereas, two research questions and hypotheses were structured and explained to lead the study. The research sample was 475 TVET teachers having technical competence for Pakistan using the random sampling technique. The instrument was an adapted questionnaire using five Likert scales. Moreover, mean and standard deviation was utilized while one-way ANOVA and Pearson correlation was used to test the hypothesis.FindingsThe findings of this study uncovered that there is no significant impact of QA of TVET programs to fulfill the need of IR 4.0 in Pakistan. But there is strong and positive association between QA of TVET programs as per the demand of IR 4.0 and level of preparedness of teachers toward it. The study suggested that in order to meet the labor market's requirements according to IR 4.0, future employment demand could be met by assuring their TVET programmers' QA and putting them into practice in accordance with the indicators and the TVET framework suggested in literature and by United Nations Educational, Scientific and Cultural Organization (UNESCO), which is widely accepted. The findings will also help to detect current trends in teaching, providing important insights in terms of QA and the focus of digitalization in TVET education.Practical implicationsThe implication of this study is that in order to influence TVET's technological development, employment and national development, policy makers, TVET principals, coordinators and teachers must work on important aspects of their access that are very important on inclusion, financing and quality – the assurance of standards, as it meets the needs of the country according to the IR 4.0 labor market.Originality/valueThis is one of the unique studies of its nature which has focused on the QA on TVET programs for the digital employment market of IR 4.0 in Pakistan and South Asia.

Published: March 2023

PurposeThis paper aims to elucidate the relationship between entrepreneurial orientation, reverse innovation and international performance of emerging economy multinational enterprises (EMNEs).Design/methodology/approachThe authors analyze archival data of Chinese limited companies between 2010 and 2016, including 11,230 firm-year observations about 1708 firms. In order to test the study’s mediation hypotheses, the authors apply an ordinary least square (OLS) regression.FindingsThe authors find evidence that the entrepreneurial orientation of EMNEs has a positive effect on reverse innovations. Furthermore, the authors find positive effects of reverse innovation on the international performance of EMNEs. This pattern of results suggests that the relationship between entrepreneurial orientation and international performance is partially mediated by reverse innovation.Practical implicationsThe study’s findings help managers in EMNEs to promote reverse innovation by building and using their entrepreneurial orientation. It also helps them to set out and gauge the chances of success of their internationalization strategies. The findings also hold relevance for firms in developed economies as well, as they may understand which emerging economy competitors stand to threaten their positions.Originality/valueThe strategic role of reverse innovations – i.e. clean slate, super value and technologically advanced products originating from emerging markets – has generated considerable research attention. It is clear that reverse innovations impact the international performance of EMNEs. Yet how entrepreneurial orientation influences international performance is still underexplored. Thus, the current study clarifies the mechanism by examining and testing the mediating role of reverse innovation among the entrepreneurial orientation–international performance link.
Sport team identification: a social identity perspective comparing local and distant fans
Authors: Lintumäki Petri , Koll Oliver 
Published: March 2023

PurposeSupporting distant teams is a frequent phenomenon. Through the lens of the social identity theory, this research aims to examine differences between local and distant fans regarding drivers of team identification.Design/methodology/approachA multigroup structural equation model was employed. The data were collected through an online survey with 1,285 sports fans.FindingsTeam distinctiveness constitutes an important aspect fueling identification for all fans, whereas congruence between own and team personality is important for local and displaced fans only. Team prestige does not impact identification for either group.Practical implicationsTo build up a base of highly identified supporters, clubs should emphasize those aspects of team brands that fans consider distinctive. When targeting local fans, clubs should also focus on communicating the brand's unique personality aspects.Originality/valueThis is the first study that assesses the potential differences behind fans' social identification with local and distant teams.

Authors: Glorieux Vita , Lo Bue Salvatore , Euwema Martin 
Published: March 2023

PurposeCrisis services personnel are frequently deployed around the globe under highly demanding conditions. This raises the need to better understand the deployment process and more especially, sustainable reintegration after deployment. Despite recent research efforts, the study of the post-deployment stage, more specifically the reintegration process, remains fragmented and limited. To address these limitations, this review aims at (1) describing how reintegration is conceptualised and measured in the existing literature, (2) identifying what dimensions are associated with the reintegration process and (3) identifying what we know about the process of reintegration in terms of timing and phases.Design/methodology/approachFollowing the preferred reporting items for systematic reviews and meta-analyses (PRISMA) protocol, the authors identified 5,859 documents across several scientific databases published between 1995 and 2021. Based on predefined eligibility criteria, 104 documents were yielded.FindingsResearch has primarily focused on descriptive studies of negative individual and interpersonal outcomes after deployment. However, this review indicates that reintegration is dynamic, multi-sector, multidimensional and dual. Each of its phases and dimensions is associated with distinct challenges.Originality/valueTo the authors’ knowledge, this is the first research that investigates reintegration among different crisis services and provides an integrative social-ecological framework that identifies the different dimensions and challenges of this process.

Published: March 2023

PurposeFor centuries, people have raised money for many purposes, and funding projects utilizing the Internet began to spread in earnest after 2010. However, there is a notable lack of research on crowdfunding projects, especially those involving sports. Given this background, this study's objective is to compare whether motivational factors may work differently depending on crowdfunding type and to analyze the impact of such factors on investments.Design/methodology/approachThis study was conducted using stimulation through artificially modified newspaper articles to measure crowdfunding motivation and investment intention. To clarify research questions, this study applied multiple regression analysis.FindingsFindings indicate that philanthropic motives and interest in projects influenced the intention to decide on funding and often had positive word-of-mouth effects. In equity-based projects, philanthropic motives and a desire to be recognized acted as drivers for both behaviors. In reward-based projects, philanthropic motives determined investment intentions, and recognition motivation and interest factors influenced word-of-mouth intention.Originality/valueThis study investigated the motivations and consequent intentions for crowdfunding in the field of the professional sports industry, which had substantive future implications for the business of sports.
