AbstractGlobal changes may direct species expansion away from their current range. When such an expansion occurs, and a species colonizes a new region, it is important to monitor the habitat used by the species and use the information for updated management strategies. Water deer is listed as Vulnerable species in IUCN Red List and restricted to east central China and the Korean Peninsula. Since 2017 water deer has expanded its range towards northeast China and the Russian Far East. Our research focuses on data collected in northeast China and the Russian Far East during 2017-2021, with the purpose of providing support for a better understanding of habitat use and provide conservation suggestions. We used MaxEnt to model species niche and distribution and predict habitat suitability for water deer and applied the circuitscape to determine possible dispersal routes for the species. There is good quality habitat for water deer in the boundary area of the Yalu and Tumen River estuaries between China, North Korea, and the Russian Far East, as well as the east and west regions of the Korean Peninsula. Elevation, distance to cropland and water sources, and presence of wetlands were the variables that positively contributed to modelling the suitable habitats. Two possible dispersal routes were determined using the circuit theory, one was across the area from North Korea to the downstream Tumen transboundary region, and the other was across North Korea to the boundary region in China and along the tiger national park in northern China. A series of protected areas in North Korea, China, and Russia may support the dispersal of water deer. The establishment of a Northeast Asia landscape conservation network would help establish monitoring and conservation planning at a broad scale, and this study provides an example for the need for such a network
Perceptual consequences of interocular imbalances in the duration of temporal integration
Authors: Chin Benjamin M. , Burge Johannes 
Published: February 2022

AbstractTemporal differences in visual information processing between the eyes can cause dramatic misperceptions of motion and depth. Processing delays between the eyes cause the Pulfrich effect: oscillating targets in the frontal plane are misperceived as moving along near-elliptical motion trajectories in depth (Pulfrich, 1922). Here, we explain a previously reported but poorly understood variant: the anomalous Pulfrich effect. When this variant is perceived, the illusory motion trajectory appears oriented left- or right-side back in depth, rather than aligned with the true direction of motion. Our data indicate that this perceived misalignment is due to interocular differences in neural temporal integration periods, as opposed to interocular differences in delay. For oscillating motion, differences in the duration of temporal integration dampen the effective motion amplitude in one eye relative to the other. In a dynamic analog of the Geometric effect in stereo-surface-orientation perception (Ogle, 1950), the different motion amplitudes cause the perceived misorientation of the motion trajectories. Forced-choice psychophysical experiments, conducted with either different spatial frequencies and/or different onscreen motion damping in the two eyes, show that the perceived misorientation in depth is associated with the eye having greater motion damping. A target-tracking experiment provided more direct evidence that the anomalous Pulfrich effect is caused by interocular differences in temporal integration and delay. These findings highlight the computational hurdles posed to the visual system by temporal differences in sensory processing. Future work will explore how the visual system overcomes these challenges to achieve accurate perception.

AbstractPost-traumatic stress disorder (PTSD) confers enhanced vulnerability to develop comorbid alcohol use disorder (AUD). Exposure to the scent of a predator, such as the fox odor TMT, has been used to model a traumatic stressor with relevance to PTSD symptomatology. Alcohol produces distinct interoceptive (subjective) effects that may influence vulnerability to problem drinking and AUD. As such, understanding the lasting impact of stressor on sensitivity to the interoceptive effects of alcohol is clinically relevant. The present study used a 2-lever, operant drug discrimination procedure to train male, Long-Evans rats to discriminate the interoceptive effects of alcohol (2 g/kg, i.g.) from water. Upon stable performance, rats underwent a 15-min exposure to TMT. Two weeks later, an alcohol dose-response curve was conducted to evaluate the lasting effects of the TMT stressor on the interoceptive effects of alcohol. The TMT group showed a leftward shift in ED50 of the dose response curve compared to controls, reflecting potentiated interoceptive sensitivity to alcohol. TMT exposure did not affect response rate. GABAergic signaling in both the anterior insular cortex (aIC) and the nucleus accumbens (Acb) is involved in the interoceptive effects of alcohol and stressor-induced adaptations. As such, follow-up experiments in alcohol-naïve rats examined neuronal activation (as measured by c-Fos immunoreactivity) following TMT and showed that TMT exposure increased c-Fos expression in the aIC and the nucleus accumbens core (AcbC). 2 weeks after TMT exposure, Gad-1 gene expression was elevated in the aIC and Gat-1 was increased in the Acb compared to controls. Lastly, the alcohol discrimination and alcohol-naïve groups displayed dramatic differences in stress reactive behaviors during the TMT exposure, suggesting that alcohol exposure may alter the behavioral response to predator odor. Together, these data suggest that predator odor stressor results in potentiated sensitivity to alcohol possibly through GABAergic adaptations in the aIC and Acb, which may be relevant to understanding PTSD-AUD comorbidity.
Multi-state occupancy model estimates probability of detection of an aquatic parasite using environmental DNA: Pseudoloma neurophilia in zebrafish aquaria

AbstractDetecting the presence of important parasites within a host and its environment is critical to understanding the dynamics that influence a pathogens ability to persist, while accurate detection is also essential for implementation of effective control strategies. Pseudoloma neurophilia is the most common pathogen reported in zebrafish (Danio rerio) research facilities. The only assays currently available for P. neurophilia, are through lethal sampling, often requiring euthanasia of the entire population for accurate estimates of prevalence in small populations. We present a non-lethal screening method to detect Pseudoloma neurophilia in tank water based on detection of environmental DNA (eDNA) from this microsporidum, using a previously developed qPCR assay that was adapted to the digital PCR (dPCR) platform. Using the generated dPCR data, a multi-state occupancy model was also implemented to predict the probability of detection in tank water under different flow regimes and pathogen prevalence. The occupancy model revealed that samples collected in static conditions were more informative than samples collected from flow-through conditions, with a probability of detection at 80% and 47%, respectively. There was also a positive correlation with the prevalence of infection in water and prevalence in fish based on qPCR.

AbstractBackgroundMapping of quantitative trait loci (QTL) associated with molecular phenotypes is a powerful approach for identifying the genes and molecular mechanisms underlying human traits and diseases. How the genetic architecture of molecular traits varies across human populations, however, has been less explored. To better understand the genetics of gene regulation in East Africans, we perform expression and splicing QTL mapping in whole blood from a cohort of 162 diverse Africans from Ethiopia and Tanzania. We assess replication of these QTLs in cohorts of predominantly European ancestry and identify candidate genes under selection in human populations.ResultsWe find the gene regulatory architecture of African and non-African populations is broadly shared, though there is a considerable amount of variation at individual loci across populations. Comparing our analyses to an equivalently sized cohort of European Americans, we find that QTL mapping in Africans improves the detection of expression QTLs and fine mapping of causal variation. Integrating our QTL scans with signatures of selection, we find several genes related to immunity and metabolism that are highly differentiated between Africans and non-Africans, as well as a gene associated with pigmentation, TMEM216, with evidence of population-specific selection in Nilo-Saharan speaking pastoralists.ConclusionExtending QTL-mapping studies beyond groups of European ancestry, particularly to diverse indigenous populations, is vital for a complete understanding of the genetic architecture of human traits and can reveal novel functional variation underlying human traits and disease.

AbstractHuman cognition and behaviors depend upon the brain’s functional connectomes, which vary remarkably across individuals. However, whether and how the functional connectome individual variability architecture is structurally constrained remains largely unknown. Using tractography- and morphometry-based network models, we observed the spatial convergence of structural and functional connectome individual variability, with higher variability in heteromodal association regions and lower variability in primary regions. We demonstrated that functional variability is significantly predicted by a unifying structural variability pattern and that this prediction follows a primary-to-heteromodal hierarchical axis, with higher accuracy in primary regions and lower accuracy in heteromodal regions. We further decomposed group-level connectome variability patterns into individual unique contributions and uncovered the structural-functional correspondence that is associated with individual cognitive traits. These results advance our understanding of the structural basis of individual functional variability and suggest the importance of integrating multimodal connectome signatures for individual differences in cognition and behaviors.

ABSTRACTThe COVID-19 vaccines effectively elicit humoral and cellular immunity against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a healthy population. This immunity decreases several months after the vaccination. However, the efficacy of the vaccine-induced immunity and its durability in patients with severe asthma on biological therapy is unknown. In this study, we evaluated the effectiveness and durability of the mRNA vaccine-induced SARS-CoV-2-specific humoral and cellular immunity in severe asthma patients on biological therapy. The study included 37 patients with severe asthma treated with anti-IgE (omalizumab, n=18), anti-IL5 (mepolizumab, n=14; reslizumab, n=4), or anti-IL5R (benralizumab, n=1) biological therapy. All patients were vaccinated with two doses of BNT162b2 mRNA vaccine (Comirnaty) at a 6-week period between the doses. We found that the COVID-19 vaccination elicited SARS-CoV-2-specific humoral and cellular immunity, which significantly declined 6 months after the second dose of the vaccine. The type of biological treatment did not affect the vaccine-elicited immunity. However, the patients’ age negatively impacted the vaccine-induced humoral response. On the other hand, no such age-related impact was observed on the vaccine-elicited cellular immunity. Our findings showed that biological therapy of patients with severe asthma does not compromise the effectiveness and durability of the COVID-19 vaccine-induced immunity.

PurposeThis study aims to provide a way to derive inter-brand similarities from user-generated content on online brand forums, which enables the authors to analyze the market structures based on consumers' actual information searching and sharing behavior online. This study further presents a method for deriving inter-brand similarities from data on how the sales of competing brands covary over time. The results obtained by the above two methods are compared to each other.Design/methodology/approachIn drawing similarities between brands, the authors utilized a newly proposed measure that modified the lift measure. The derived similarity information was applied to multidimensional scaling (MDS) to analyze the perceived market structure. The authors applied the proposed methodology to the imported car market in South Korea.FindingsIn light of some clear information such as the country of origin, the market structure derived from the presented methodology was seen to accurately reflect the consumer's perception of the market. A significant relevance has been found between the results derived from user-generated online content and sales data.Originality/valueThe presented method allows marketers to track changes in competitive market structures and identify their major competitors quickly and cost-effectively. This study can contribute to improving the utilization of the overflowing information in the big data era by proposing methods of linking new types of online data with existing market research methods.

Published: February 2022

Purpose There is a dearth of research on how immigrants' cognitive attributes influence their willingness to be self-employed. To offset this paucity, the current study draws on the insights of social cognitive theory (SCT) to examine the immigrants' entrepreneurial alertness.Design/methodology/approach The authors hired Qualtrics to recruit educated, working immigrants in the USA and tested the hypotheses using a sample of 555 highly educated, employed immigrants from 92 home countries.Findings This study finds that immigrants' cognitive cultural intelligence (CQ) contributes to entrepreneurial alertness in a positive way. In addition, immigrants' perceived environmental differences and global identity positively moderate the relationship between cognitive CQ and entrepreneurial alertness.Originality/value This research provides a clear picture of how cognitive CQ impacts immigrants' entrepreneurial alertness; thus, the findings of this study offer ample implications for policymakers. By applying SCT, the current study extended research on immigrants' entrepreneurial alertness by shifting the focus from their individual (e.g. demographic background) or family characteristics to their cognitive attributes. This study suggests that policymakers and entrepreneurship education programs in the U.S.A. should consider offering various types of cultural training programs.

PurposeThis study aims to examine the impact of transformational leadership on green innovation and green learning in construction supply chains.Design/methodology/approachA theoretical framework of research hypotheses between transformational leadership, green learning and green innovation is developed. Using a survey questionnaire, data are collected from construction firms in Vietnam. Structural equation modeling is used to test the research hypotheses.FindingsThe results indicate that transformational leadership promotes both green learning and green innovation (i.e. green product innovation and green process innovation) while green learning positively affects green process innovation. Furthermore, it is found that green learning mediates the linkage between transformational leadership and green process innovation.Research limitations/implicationsThis study contributes to the development of leadership research in construction by showing the significance of leadership at the supply chain level.Originality/valueLeadership is regarded as a key factor for most organizations' success and competitive advantages. In construction, leadership has been widely studied at the project and organizational levels while its important role is also explored at the supply chain level. Nevertheless, in terms of construction supply chains, there has been still very limited evidence about the effects of transformational leadership. Thus, this study fills the gap in knowledge by empirically examining the relationships between transformational leadership, green learning and green innovation.
The interaction of social influence and message framing on children’s food choice
Authors: Khan Huda , Lee Richard , Khan Zaheer 
Published: February 2022

PurposeObesity leads to increased mortality and morbidity among children, as well as when they turn adults. Melding marketing theories in social influence and message framing, this study aims to examine how compliance versus conformance social influence, each framed either prescriptively or proscriptively, may guide children’s choice of healthy versus unhealthy food.Design/methodology/approachThis study conducted two experiments in a Pakistani junior school. Experiment 1 exposed children to either a prescriptive or a proscriptive compliance influence. Experiment 2 involved a 2 (prescriptive vs proscriptive compliance influence) × 2 (supportive vs conflicting conformance-influence) between-subjects design. Participants in both studies answered an online survey after being exposed to the social-influence messages.FindingsExperiment 1 showed proscriptive was stronger than prescriptive compliance influence in nudging children to pick fruits (healthy) over candies (unhealthy). However, frequency of fruits dropped as susceptibility to compliance strengthened. Experiment 2 found that a proscriptive compliance influence reinforced by a supportive conformance-influence led to most children picking fruits. However, a conflicting conformance influence was able to sway some children away from fruits to candies. This signalled the importance of harmful peer influence, particularly with children who were more likely to conform.Research limitations/implicationsChildhood is a critical stage for inculcating good eating habits. Besides formal education about food and health, social influence within classrooms can be effective in shaping children’s food choice. While compliance and conformance influence can co-exist, one influence can reinforce or negate the other depending on message framing.Practical implicationsIn developing countries like Pakistan, institutional support to tackle childhood obesity may be weak. Teachers can take on official, yet informal, responsibility to encourage healthy eating. Governments can incentivise schools to organise informal activities to develop children’s understanding of healthy consumption. Schools should prevent children from bringing unhealthy food to school, so that harmful peer behaviours are not observable, and even impose high tax on unhealthy products or subsidise healthy products sold in schools.Originality/valueThis study adopts a marketing lens and draws on social influence and message framing theory to shed light on children’s food choice behaviour within a classroom environment. The context was an underexplored developing country, Pakistan, where childhood obesity is a public health concern.

PurposeThe main aim of the research is to investigate the relationships among primary school teachers' perceptions on coworker social loafing, organizational justice and task visibility. It is also examined whether teachers' opinions on organizational justice and task visibility are statistically significant predictors of their perceptions on coworker social loafing.Design/methodology/approachResearch was designed by using correlational survey model. The sample of the study consisted of 656 teachers selected by cluster sampling method among primary school teachers working in Eskisehir.FindingsResearch results showed that teachers' perceptions on their coworkers' social loafing levels were low, while their perceptions on organizational justice and task visibility were high. Furthermore, it was determined that distributive justice and task visibility predicted 13% of teachers' perceptions about their coworkers' social loafing levels. According to this finding, as teachers' perceptions of distributive justice and task visibility increase, their perceptions about coworker social loafing decrease.Originality/valueThis paper is unique in terms of examining the most probable antecedents of social loafing perceptions according to the literature among teachers which are organizational justice and task visibility together in Turkey context. The facts that social loafing studies are rare and hardly encountered among studies in the field of educational administration distinguish this study and make it appropriate to be published in a journal whose scope includes creation of an environment in which the management of resources provides the most efficient outputs.
