AbstractDiffusion magnetic resonance images may suffer from geometric distortions due to susceptibility induced off resonance fields, which cause geometric mismatch with anatomical images and ultimately affect subsequent quantification of microstructural or connectivity indices. State-of-the art diffusion distortion correction methods typically require data acquired with reverse phase encoding directions, resulting in varying magnitudes and orientations of distortion, which allow estimation of an undistorted volume. Alternatively, additional field maps acquisitions can be used along with sequence information to determine warping fields. However, not all imaging protocols include these additional scans and cannot take advantage of state-of-the art distortion correction. To avoid additional acquisitions, structural MRI (undistorted scans) can be used as registration targets for intensity driven correction. In this study, we aim to (1) enable susceptibility distortion correction with historical and/or limited diffusion datasets that do not include specific sequences for distortion correction and (2) avoid the computationally intensive registration procedure typically required for distortion correction using structural scans. To achieve these aims, we use deep learning (3D U-nets) to synthesize an undistorted b0 image that matches geometry of structural T1w images and intensity contrasts from diffusion images. Importantly, the training dataset is heterogenous, consisting of varying acquisitions of both structural and diffusion. We apply our approach to a withheld test set and show that distortions are successfully corrected after processing. We quantitatively evaluate the proposed distortion correction and intensity-based registration against state-of-the-art distortion correction (FSL topup). The results illustrate that the proposed pipeline results in b0 images that are geometrically similar to non-distorted structural images, and more closely match state-of-the-art correction with additional acquisitions. In addition, we show generalizability of the proposed approach to datasets that were not in the original training / validation / testing datasets. These datasets included varying populations, contrasts, resolutions, and magnitudes and orientations of distortion and show efficacious distortion correction. The method is available as a Singularity container, source code, and an executable trained model to facilitate evaluation.

ABSTRACTParticulate matter (PM) air pollution causing significant cardiopulmonary mortality via macrophage-driven lung inflammation; however, the mechanisms are not completely understood. RNA-sequencing demonstratedAcod1(Aconitate decarboxylase 1) as one of the top genes induced by PM in macrophages.Acod1encodes a mitochondrial enzyme that produces itaconate, which has been shown to exert anti-inflammatory effects via NRF2 after LPS. Here, we demonstrate that PM induces Acod1 and itaconate, which reduced mitochondrial respiration via complex II inhibition. UsingAcod1-/-macrophages, we found that Acod1/endogenous itaconate was not required for PM-induced inflammation or NRF2 activation. In contrast to endogenous itaconate, exogenous cell permeable form of itaconate (4-octyl itaconate (OI)) attenuated the PM-induced inflammation and activated NRF2 but NRF2 was not required for the anti-inflammatory effects of OI. We conclude that the effects of itaconate production on inflammation are stimulus-dependent, and that there are important differences between endogenous and exogenously-applied itaconate.
Is financial education an effective means to improve financial literacy? Evidence from rural China
Authors: ZHang Huanhuan , Xiong Xueping 
Published: January 2020

Purpose
Using survey data from Shandong, Henan and Guizhou provinces of China, the purpose of this paper is to accurately measure the impact of rural residents’ financial education on financial literacy.

Design/methodology/approach
This paper chooses one province from the Eastern, Central and Western Regions of China, namely, Shandong, Henan and Guizhou, respectively, and 1,565 samples are obtained through a questionnaire survey. First, the paper constructs a financial literacy assessment framework and, then, scores the financial literacy of the respondents. Second, using ordinary least squares, feasible generalized least squares method and forward search method, the paper estimates the impact factors of financial literacy level. To avoid sample selection errors and endogeneity problems, the authors divide the respondents into treatment group (participated in financial education) and control group (non-participating in financial education) and, then, adopt propensity score matching (PSM) to analyze the impact of rural residents’ financial education on financial literacy.

Findings
The results show that education level and risk level have significant impact on rural residents’ participation in financial education, and some unobservable abilities and qualities also affect their participation. Therefore, the process of rural residents’ participation in financial education exists, which gives rise to self-selection and endogeneity problems; financial education is promoting rural residents’ financial literacy, but the effect of promotion becomes smaller after taking into account sample self-selection and endogenous problems. Rural residents of female, higher age, single, higher education level, higher parental education level, agricultural type, higher family annual per capita income and lower risk level show stronger effects on their financial literacy level, if they participate in financial education.

Research limitations/implications
The survey sample was drawn from three provinces randomly but the site selection was not random. The implication is in rural China, financial education has positive effect on residents’ financial literacy level but considering the sample self- selection and endogenous nature, its impact becomes smaller.

Practical implications
The government should encourage rural residents to participate fully in financial education activities, especially those with a low educational level, low risk preference and mainly engaged in agricultural production.

Originality/value
The effect of financial education on financial literacy has not reached a consistent conclusion, and there is fewer quantitative discussion about this issue. The originality of this paper is based on the Organization for Economic Co-operation and Development evaluation index system; this paper constructs the evaluation index system of rural residents’ financial literacy in China and uses the PSM method to accurately measure the effect of financial education on financial literacy.

Published: January 2020

PurposeSeveral years after the regularization of microfinance activity in Côte d’Ivoire, smallholder farmers’ access to microfinance credits still remains marginal. The purpose of this paper is to identify and analyze key determinants of access to microfinance credit in Sassandra-Marahoué District.Design/methodology/approachA total of 150 smallholder farmers were randomly sampled using an interview guide and semi-structured questionnaires. Univariate statistics and Probit binary modeling were employed for data analyses.FindingsResults revealed that socio-economic/demographic characteristics of smallholder farmers and credit requirements imposed by microfinance institutions (MFIs) are key determinants of smallholder farmers’ access to microfinance credits in the district.Research limitations/implicationsAlthough, the authors shed light on the determinants of microfinance credit access for smallholder farmers in this district, the study focused on a single source of financial credit. Future research will need to explore the determinants of credit demand and the choice between different sources of rural credits in Côte d’Ivoire.Practical implicationsThe findings suggest that MFIs seldom take into account smallholder farmers who are not engaged in off-farm income-generating activities and savings account; and those with low level of education. Sensitization programs on the importance of savings mobilization and credit policy by MFIs will potentially increase smallholder’s knowledge on credit access requirements and thereby increased access.Originality/valueTo the authors’ knowledge, this is the first study investigating determinants of smallholder farmers’ access to microfinance credits in Côte d’Ivoire specifically in the Sassandra-Marahoué District. The results of this study will serve as a guide for MFIs for improving smallholder farmers’ access to credit.
Critical success factors for large building construction projects
Authors: Mathar Hasan , Assaf Sadi , Hassanain Mohammad A. , Abdallah Abdullatif , Sayed Ahmed M.Z. 
Published: January 2020

Purpose
The literature revealed a limited number of studies on critical success factors (CSFs) in Saudi Arabia. These studies were either outdated, covered limited factors or focused on very specific issues of a project. In response to this knowledge gap, the purpose of this paper is to identify and assess the factors which affect the success of construction projects in Saudi Arabia.

Design/methodology/approach
In all, 91 CSFs were identified from the literature, and grouped under eight categories according to categorization schemes adopted by earlier studies and common characteristics shared by the factors. A questionnaire survey was adopted since it permits the collection of large volumes of data in a short period. In total, 61 responses from industry experts were used to compute the significance index for each factor and rank the most CSFs.

Findings
Contractors viewed the three most significant CSFs as “competency and capability of the contractors’ key personnel in different disciplines,” “adequacy of labor resources and their skills” and “the impact of the project on the public.” Consultants viewed the three most significant CSFs as “competency and capability of the consultants’ key personnel in different disciplines,” “clear communication channels between the owner/PM and the designer” and “PM competency, authority and involvement.”

Originality/value
Although a significant number of studies have investigated CSFs for construction projects, these studies do not provide an extensive list of CSFs, and none have studied CSFs in large-scale construction projects in Saudi Arabia from the viewpoint of two key stakeholders. This study attempts to address this knowledge gap.
How information acceptance model predicts customer loyalty?
Authors: Park Tiwa 
Published: January 2020

Purpose
This study aims to explore the influence of electronic word of mouth (eWOM) in social media on customer loyalty by using the information acceptance model (IACM). For this purpose, this study identified the relationship of attitude towards information, information credibility, information quality and information with information usefulness. Later, the relation of information usefulness and information adoption was examined. According to the IACM, this information adoption and attitude towards information can affect behavioural outcomes of customer, and the authors used customer loyalty as a behavioural outcome.

Design/methodology/approach
This study collected the data from students enrolled in different universities of Thailand. More specifically, those students were considered appropriate for study who were active Facebook users. Therefore, a questionnaire was posted in 83 different Facebook groups of university students, from which 771 students responded properly. SPSS and AMOS 24 were used to conduct data reliability, descriptive and correlation analysis, confirmatory factor analysis (CFA), and structural equation modelling (SEM).

Findings
The study found that credibility, quality, usefulness and adoption of information, need of information and attitude towards information are the key factors of eWOM in social media that influence consumers’ loyalty.

Practical implications
This study will be helpful for marketing managers in studying patterns of customer loyalty because many studies have previously examined purchase behaviour or purchase intention only. Moreover, it will provide framework to marketers for understanding the influence of eWOM information in social media on customer loyalty.

Originality/value
This study is to explore the effect of credibility, quality, usefulness and adoption of information, need of information and attitude towards information on consumers’ loyalty.
Factors affecting awareness of preparedness after moderate earthquakes
Authors: Moon Ji-Won , Hwang Ha , Chung Ji-Bum 
Published: January 2020

Purpose
The purpose of this paper is to examine how experiencing moderate earthquakes influences risk perception and preparedness.

Design/methodology/approach
An online survey was conducted on a nationally representative sample of Korean adults after the moderate earthquake in Pohang in 2017. Statistical analyses were conducted to identify the determinants of willingness to pay (WTP) for seismic retrofitting and earthquake insurance.

Findings
The results show that risk perception, housing ownership, earthquake experience and income level significantly influenced WTP for seismic retrofitting and earthquake insurance. The results also indicate that a greater number of damage-free earthquake experiences reduced the WTP that could be explained by normalcy bias. Finally, people who believed that the Pohang earthquake might be an example of induced seismicity (i.e. triggered by the geothermal power plant) tended to have a lower WTP for seismic retrofitting.

Originality/value
This study offers valuable findings on public attitudes about enhancing earthquake preparedness policies in moderate earthquake zones, regions that few studies have examined despite their high vulnerability due to a lack of preparedness.
Wayfinding during a wildfire evacuation
Authors: Brachman Micah L. , Church Richard , Adams Benjamin , Bassett Danielle 
Published: January 2020

Purpose
Emergency evacuation plans are often developed under the assumption that evacuees will use wayfinding strategies such as taking the shortest distance route to their nearest exit. The purpose of this paper is to analyze empirical data from a wildfire evacuation analyzed to determine whether evacuees took a shortest distance route to their nearest exit and to identify any alternate wayfinding strategies that they may have used.

Design/methodology/approach
The wildfire evacuation analysis presented in this paper is the outcome of a natural experiment. A post-fire online survey was conducted, which included an interactive map interface that allowed evacuees to identify the route that they took. The survey results were integrated with several additional data sets using a GIS. Network analysis was used to compare the routes selected by evacuees to their shortest distance routes, and statistical hypothesis testing was employed to identify the wayfinding strategies that may have been used.

Findings
The network analysis revealed that 31 percent of evacuees took a shortest distance route to their nearest exit. Hypothesis testing showed that evacuees selected routes that had significantly longer distances and travel times than the shortest distance routes, and indicated that factors such as the downhill slope percentage of routes and the elevation of exits may have impacted the wayfinding process.

Research limitations/implications
This research is best regarded as a spatiotemporal snapshot of wayfinding behavior during a single wildfire evacuation, but could inspire additional research to establish more generalizable results.

Practical implications
This research may help emergency managers develop more effective wildfire evacuation plans.

Originality/value
This research presents an analysis of an original data set that contributes to the broader body of scientific knowledge on wayfinding and spatial behavior during emergency evacuations.
Do spouses influence each other's stated son preference?
Authors: Robitaille Marie-Claire , Chatterjee Ishita 
Published: January 2020

Purpose
This paper aims to understand the motivations behind married men preferring sons and to quantify the association between a couple’s stated son preferences. Son preference is an endemic problem in India. With half a million female foetuses aborted each year, the root causes of son preference in India have been widely studied. Little is known, however, on how couples mutually decide on their desired child sex-ratio.

Design/methodology/approach
Using data from the third National Family and Health Survey, the authors apply three-stage least square and optimal general method of moment methods to demonstrate association. Robustness checks are performed on plausibly exogenous instrumental variables and selection issues in the marriage market.

Findings
The authors show that their spouse's son preference is by far the most significant factor associated with a person's own stated son preference. The association between spouse's stated son preference is observed only for couples being married for three to five years. It is postulated that this is the critical period when sex-selective abortion decisions are being made.

Originality/value
The focus of existing empirical studies is nearly always on the mother's son preference only. The hypothesis is that spouses mutually influence each other’s preferences and models estimating determinants of son preference should include preferences of both spouses. To the best of the authors’ knowledge, this is the first attempt to understand the motivations of married men towards preferring sons and quantify the association between spouse's stated son preference and respondent's stated son preference.
When do abusive leaders experience guilt?
Authors: Shum Cass , Ausar Kweisi , Tu Min-Hsuan 
Published: January 2020

Purpose
Drawing from the appraisal theory, this paper aims to examine the conditions under which abusive leaders experience guilt and suggests that guilt motivates leaders to help followers.

Design/methodology/approach
A scenario study with a sample of 285 hospitality supervisors was used to test the theoretical model. Path analyses were conducted to test the three-way-moderated mediation model.

Findings
Results show a three-way interaction among enacted abuse, managerial abuse and agreeableness on the guilt: leaders are more likely to experience guilt over their enacted abusive supervision when they do not perceive their direct manager as abusive and when they are agreeable. Moreover, guilt mediates the relationship between enacted abuse and a leader’s intention to help their followers.

Research limitations/implications
This study shows that abusive supervisors pay an emotional cost for their enacted abuse (in terms of guilt).

Practical implications
Hospitality organization should assign non-abusive mentors to leaders, especially agreeable ones, to detect and reduce abusive supervision.

Originality/value
First, this study addressed the lack of research on the effect of abusive supervision on the abusers by studying the conditions under which abusive leaders experience guilt. Second, this study shows that because of guilt, abusive leaders have a higher intention to help their followers. It explains why abusive leaders can be helpful.
The spatiality of men who go missing on a night out
Authors: Newiss Geoff , Greatbatch Ian 
Published: January 2020

Purpose
The purpose of this paper is to quantify the risk of fatality for men who are reported missing following a night out. Additionally, the paper aimed to develop search heuristics to inform the development of search strategies, through an examination of the key geographical points involved in these cases.

Design/methodology/approach
Cases were identified, and data collected, from online media sources supplemented with a request to UK police forces and a search of the UK Missing Persons Unit database. In total, 96 cases which occurred over a five-and-a-half-year period in the UK were included. The study compares the profile of fatalities that result from disappearances occurring in different types of geographical area. Location data were georeferenced allowing Euclidean distances between geographical locations to be generated.

Findings
In total, 60 per cent of disappearances lasting longer than 48 h resulted in fatality, rising to almost all cases after three days missing. In 89 per cent of cases bodies are recovered from water; 11 per cent on land after the individual died from a fall, hypothermia or a drugs overdose.

Practical implications
Search strategies can be informed by a consideration of the type of area the person was socialising (high night-time economy through to rural areas) and the geography of subsequent sightings.

Originality/value
In focusing on the specific circumstances of a disappearance rather than an individual’s personal characteristics, the paper offers an innovative approach to understanding risk (i.e. what is the likelihood of a particular outcome occurring) and the development of heuristics for search strategies in missing person cases.
Personal resources and knowledge workers’ job engagement
Authors: Toth Ilona , Heinänen Sanna , Nisula Anna-Maija 
Published: January 2020

Purpose
The purpose of this paper is to investigate the impact of personal resources on knowledge workers’ job engagement in the contemporary economy. Work itself and work environments are currently undergoing fundamental changes. As such, the focus of engagement research is shifting to an interest in personal resources and the psychological capital of knowledge workers.

Design/methodology/approach
This paper proposes a theoretical model based on a modern interpretation of the conservation of resources theory concerning the relationship between personal resources (self-efficacy, organization-based self-esteem and satisfaction with life) in relation to the three dimensions of job engagement (physical, emotional and cognitive). The proposed model is tested with structural equation modelling (LISREL).

Findings
The results from the analysis of data collected from Finnish university graduates (N = 103) show that the three dimensions of job engagement are strongly influenced by organization-based self-esteem and satisfaction with life but, surprisingly, not by self-efficacy.

Practical implications
Through understanding the impact of personal resources on knowledge workers’ job engagement, organizations can enhance their human relations management practices and develop better support mechanisms for their knowledge workers.

Originality/value
This paper provides empirical evidence for the influence of personal resources on knowledge workers’ job engagement. There is a lack of empirical studies on knowledge workers’ job engagement in the contemporary economy. The changing nature of the way work is being carried out in the contemporary economy raises the importance of personal resources as a key resource for knowledge workers’ job engagement.
