Published: September 2018

AbstractAlthough hybridization has played an important role in the evolution of many species, phylogenetic reconstructions that include hybridizing lineages have been historically constrained by the available models and data. Recently, the combined development of high-throughput sequencing and evolutionary network models offer new opportunities for phylogenetic inference under complex patterns of hybridization in the context of incomplete lineage sorting. Restriction site associated DNA sequencing (RADseq) has been a popular sequencing technique for evolutionary reconstructions of close relatives in the Next Generation Sequencing (NGS) era. However, the utility of RADseq data for the reconstruction of complex evolutionary networks has not been thoroughly discussed. Here, we used new molecular data collected from diploid perennialMedicagospecies using single-digest RADseq to reconstruct evolutionary networks from gene trees, an approach that is computationally tractable with datasets that include several species and complex patterns of hybridization. Our analyses revealed that complex network reconstructions from RADseq-derived gene trees were not robust under variations of the assembly parameters and filters. Filters to exclusively select loci with high phylogenetic information created datasets that retrieved the most anomalous topologies. Conversely, alternative clustering thresholds or filters on the number of samplesperlocus affected the level of missing data but had a lower impact on networks. When most anomalous networks were discarded, all remaining network analyses consistently supported a hybrid origin forM. carstiensisandM. cretacea.
Gene duplication accelerates the pace of protein gain and loss from plant organelles
Authors: Costello Rona , Emms David M. , Kelly Steven 
Published: September 2018

Introductory paragraphA hallmark of eukaryotic cells is the compartmentalisation of intracellular processes into specialised membrane-bound compartments known as organelles. Plant cells contain several such organelles including the nucleus, chloroplast, mitochondrion, peroxisome, golgi, endoplasmic reticulum and vacuole. Organelle biogenesis and function is dependent on the concerted action of numerous nuclear-encoded proteins which must be imported from the cytosol (or endoplasmic reticulum) where they are made. Using phylogenomic approaches coupled to ancestral state estimation we show that the rate of change in plant organellar proteome content is proportional to the rate of molecular sequence evolution such that the proteomes of chloroplasts and mitochondria lose or gain ~3.2 proteins per million years. We show that these changes in protein targeting have predominantly occurred in genes with regulatory rather than metabolic functions, and thus altered regulatory capacity rather than metabolic function has been the major theme of plant organellar evolution. Finally we show gain and loss of protein targeting occurs at a higher rate following gene duplication events, revealing that gene and genome duplication are a key facilitator of organelle evolution.
Endothelial cells filopodia participation in the anastomosis of CNS capillaries
Authors: Marin-Padilla Miguel , Howard Louisa 
Published: September 2018

By combining the classic Golgi method and the electron microscope, we have gained a better understanding of the anastomosis of CNS blood capillaries. The participation of growing capillary’ leading endothelial cells filopodia in the anastomotic process is described. The two approaching capillaries leading endothelial cells filopodia intermingle and interact forming complex conglomerates with narrow spaces filled with proteinaceous material (possibly basal lamina) secreted by them. The presence of tight junctions among the filopodia corroborates their vascular nature. Their presence also suggests a different endothelial cells origin as will those from the two approaching capillaries. The original narrow spaces coalesce into larger ones leading to the eventual formation of a single one that will interconnect (anastomose) the two capillaries. The newly formed post-anastomotic CNS capillaries are rather small with irregular and narrow lumina that might permit the passage of fluid but not yet of blood cells. Eventually, the new capillaries lumina will enlarge permitting the passage of blood cells.Funding informationThe M. M-P.

Using children’s search patterns to predict the quality of their creative problem solving
Authors: Olivares-Rodríguez Cristian , Guenaga Mariluz , Garaizar Pablo 
Published: September 2018

Purpose
The purpose of this paper is to propose a computational model that implicitly predict the children’s creative quality of solutions by analyzing the query pattern on a problem-solving-based lesson.

Design/methodology/approach
A search task related to the competencies acquired in the classroom was applied to automatically measure children’ creativity. A blind review process of the creative quality was developed of 255 primary school students’ solutions.

Findings
While there are many creativity training programs that have proven effective, many of these programs require measuring creativity previously which involves time-consuming tasks conducted by experienced reviewers, i.e. far from primary school classroom dynamics. The authors have developed a model that predicts the creative quality of the given solution using the search queries pattern as input. This model has been used to predict the creative quality of 255 primary school students’ solutions with 80 percent sensitivity.

Research limitations/implications
Although the research was conducted with just one search task, participants come from two different countries. Therefore, the authors hope that this model provides detection of non-creative solutions to enable prompt intervention and improve the creative quality of solutions.

Originality/value
This is the first implicit classification model of query pattern in order to predict the children’ creative quality of solutions. This model is based on a conceptual relation between the concept association of creative thinking and query chain model of information search.
Coupled analysis of vehicle stability in crosswind on low adhesion road
Authors: Li Shuya , Gu Zhengqi , Huang Taiming , Chen Zhen , Liu Jun 
Published: September 2018

Purpose
The purpose of this paper is to develop a two-way coupling approach for investigating the aerodynamic stability of vehicles under the combined effect of crosswind and road adhesion.

Design/methodology/approach
The author develops a new two-way coupling approach, which couples large eddy simulation with multi-body dynamics (MBD), to investigate the crosswind stability on three different adhesion roads: ideal road, dry road and wet road. The comparison of the results obtained using the traditional one-way coupling approach and the new two-way coupling approach is also done to assess the necessity to use the proposed coupling technique on low adhesion roads, and the combined effect of crosswind and road adhesion on vehicle stability is analyzed.

Findings
The results suggest that the lower the road adhesion is, the larger deviation a vehicle generates, the more necessary to conduct the two-way coupling simulation. The combined effect of the crosswind and road adhesion can decrease a vehicle’s lateral motion on a high adhesion road after the disappearing of the crosswind. But on a low adhesion road, the vehicle tends to be unstable for its large head wind angle. The vehicle stability in crosswind on a low adhesion road needs more attention, and the investigation should consider the coupling of aerodynamics and vehicle dynamics and the combined effect of crosswind and road adhesion.

Originality/value
Developing a new two-way coupling approach which can capture the complex vehicle structures and the road adhesion with MBD model and the completed fluid filed structure with CFD model. The present study might be the first study considering the coupling of crosswind and low adhesion road. The proposed two-way coupling approach will be useful for researchers who study vehicle crosswind stability.
Integral transform solution of natural convection in a cylinder cavity with uniform internal heat generation
Authors: Fu Guangming , An Chen , Su Jian 
Published: September 2018

Purpose
The purpose of this study is to propose the generalised integral transform technique to investigate the natural convection behaviour in a vertical cylinder under different boundary conditions, adiabatic and isothermal walls and various aspect ratios.

Design/methodology/approach
GITT was used to investigate the steady-state natural convection behaviour in a vertical cylinder with internal uniformed heat generation. The governing equations of natural convection were transferred to a set of ordinary differential equations by using the GITT methodology. The coefficients of the ODEs were determined by the integration of the eigenfunction of the auxiliary eigenvalue problems in the present natural convection problem. The ordinary differential equations were solved numerically by using the DBVPFD subroutine from the IMSL numerical library. The convergence was achieved reasonably by using low truncation orders.

Findings
GITT is a powerful computational tool to explain the convection phenomena in the cylindrical cavity. The convergence analysis shows that the hybrid analytical–numerical technique (GITT) has a good convergence performance in relatively low truncation orders in the stream-function and temperature fields. The effect of the Rayleigh number and aspect ratio on the natural convection behaviour under adiabatic and isothermal boundary conditions has been discussed in detail.

Originality/value
The present hybrid analytical–numerical methodology can be extended to solve various convection problems with more involved nonlinearities. It exhibits potential application to solve the convection problem in the nuclear, oil and gas industries.

Authors: Alsabery Ammar I. , Tayebi Tahar , Chamkha Ali J. , Hashim Ishak 
Published: September 2018

PurposeThe purpose of this paper is to study problem of conjugate MHD natural convection of Al2O3-water nanofluid in a square cavity with conductive inner block using Buongiorno’s two-phase model numerically.Design/methodology/approachAn isothermal heater is placed on the left wall of the square cavity, while the right wall is maintained at a constant cold temperature. The horizontal top and bottom walls are kept adiabatic. The boundaries of the annulus are assumed to be impermeable, the fluid within the cavity is a water-based nanofluid having Al2O3nanoparticles. The Boussinesq approximation is applicable. The governing equations subject to the boundary conditions are solved using the finite difference method.FindingsNumerical results are presented graphically in the form of streamlines, isotherms and nanoparticles distributions as well as the local and average Nusselt numbers. The results show that the effect of the nanoparticles addition on the average Nusselt number is essential for low Rayleigh, high Hartmann and high values of length ratio when attenuated the convective flow.Originality/valueAccording to exist studies and to the authors’ best knowledge, so far, there have been no studies of conjugate natural convection of Al2O3-water nanofluid in a square cavity with a conductive inner block using Buongiorno’s two-phase model with the effect of the magnetic field. Thus, the authors believe that this work is new and valuable. The aim of this study is to investigate the MHD natural convection of Al2O3-water nanofluid in a square cavity with conductive inner block using Buongiorno’s two-phase model.

Family ownership and financial reporting quality: Iranian evidence
Authors: Mousavi Shiri Mahmoud , Salehi Mahdi , Abbasi Fatemeh , Farhangdoust Shayan 
Published: September 2018

Purpose
In the process of reporting accounting information, the auditor’s objective is to detect possible misstatements and errors in accounting information. Audit evidence aids auditors in providing reasonable assurance about the quality of financial reporting. Studying the quality of family firms’ financial reporting is of higher importance relative to non-family firms due to lower risk of accounting manipulation. Therefore, the purpose of this paper is to examine the relationship between family ownership structure and financial reporting quality from an auditing perspective.

Design/methodology/approach
To analyze the research hypotheses, the authors use a sample data consisted of 221 companies listed on the Tehran Stock Exchange (including 52 family and 169 non-family firms) over a five-year span from 2011 to 2015.

Findings
Using multivariate regression analysis of panel data, our results indicate that audit risk in family firms is lower than their counterparts. Likewise, the findings are indicative of lower audit fees paid by family firms as compared to non-family ones. The authors also find that auditors put more effort in family firms and thus audit effort is more significant for these kinds of firms.

Originality/value
The study focuses on family ownership and financial reporting quality in a developing country like Iran and the results of the study may be beneficial to other developing nations, as Iran stock market possesses some unique features which are not normally prevailing in other equity markets, even in the Middle East.
Workplace incivility and knowledge hiding behavior: does personality matter?
Authors: Arshad Rasidah , Ismail Ida RosnitaI 
Published: September 2018

Purpose
The purpose of this paper is to examine the relationship between workplace incivility and knowledge hiding, and role of personality disposition (neuroticism) in moderating such relationships.

Design/methodology/approach
Data were collected from 108 employees nested in 18 teams from private sectors via survey questionnaire. Confirmatory factor analysis and hierarchical regression models were used to test the hypotheses.

Findings
The findings show that the higher the level of workplace incivility experienced by the team members, the higher the tendency for them to hide knowledge and this relationship is moderated by neuroticism. Specifically, the relationship was found to be stronger for those employees high in neuroticism compared to those low in neuroticism.

Practical implications
The study offers important implication in term of knowledge hiding prevention or reduction. The behavior can be reduced by creating awareness among employees on the importance of civility at work via campaign, realistic job preview and leading by example. To manage the effect of neuroticism, managers need to identify those high in the trait and provide them with training on how to better regulate and manage negative emotions in the workplace.

Originality/value
The study contributes to the research on knowledge hiding behavior by advancing the understanding of organizational and personal factors that can influence knowledge hiding among employees working in team. It is the first to propose and empirically validate the predictive effect of workplace incivility on knowledge hiding. It also addresses the usefulness of examining personality disposition in understanding the relationship between workplace incivility and knowledge hiding behavior.
Effects of cognitive and affective trust on online customer behavior
Authors: Punyatoya Plavini 
Published: September 2018

PurposeAlthough prior works in online retailing have addressed the influence of trust on customer responses, they conceptualized trust as a single dimension. Based on social-psychological literature and sociological literature, this study proposes that consumer trust in an online retailer has two principal forms: cognitive trust and affective trust. The purpose of this paper is to examine various factors influencing the development of each form of customer online trust and the subsequent effect on customer satisfaction (CS) and loyalty intention (LI).Design/methodology/approachSurvey approach is employed to validate the research model. Data are collected from 334 Indian consumers and using structural equation modeling the causal pathways of the model are investigated.FindingsThe results show that cognitive trust and affective trust are empirically distinguished variables in online retailing context. Cognitive trust and affective trust are found to mediate the relationship between perceived website quality, security and privacy policy, prior-interaction experience, perceived e-tailer reputation and shared value and CS. CS also positively influences LI toward the online retailer.Practical implicationsThe paper provides interesting insights about Indian consumers’ evaluation of online retailers. These useful insights would enable both international and national online retailers to develop and apply different strategies to improve customer trust, which is a key driver of CS and LI.Originality/valueDrawing from signaling theory and organizational studies literature, this paper investigates the relationship between different antecedents and affect-based and cognition-based trust in online retailing context. In particular, this is the first study to examine multi-dimensional nature of consumer trust in online retailing context. Besides, this paper clearly shows that cognitive trust and affective trust are the mediating variables that positively affect CS toward online retailers and help in building strong customer LI.

Published: September 2018

AbstractObjectiveOur objective was to examine the impact of a human factor‐designed multimodal intervention on the proportion of unused peripheral i.v. cannula (PIVC) insertion in our ED.MethodsA pre‐ and post‐multimodal intervention retrospective cohort study was conducted using a structured electronic medical record review within a single adult tertiary ED in Australia. Pre‐intervention data was collected 30 days prior to the multimodal intervention, with 30 day post‐intervention data collected 3 months after the intervention commenced. The rates of PIVC inserted, the unused rate and the unused but appropriately inserted cannulas were the main outcome measures.ResultsIntravenous cannula insertion rates decreased by 12.9% (95% confidence interval [CI] 12.19–13.61) between the pre‐intervention (1413/4167 [33.9%]; 95% CI 32.5–35.4) and post‐intervention cohort (928/4421 [21.0%]; 95% CI 19.8–22.2). An analysis of 754 cases (376 pre‐intervention and 378 post‐intervention) showed that 139 of 376 (37.0%; 95% CI 32.1–42.1) i.v. cannulas were unused pre‐intervention, while 73 of 378 (19.3%; 95% CI 15.4–23.7) was unused post‐intervention; an absolute reduction of 17.7% (95% CI 14.98–20.42). The relative risk of an unused i.v. cannula was 0.52 (95% CI 0.41–0.67). The proportion of unused but appropriately inserted i.v. cannulas remained unchanged in both cohorts, with a relative risk of 0.91 (95% CI 0.58–1.42).ConclusionOur multimodal intervention successfully reduced the number of unused PIVCs inserted in the ED, with a reduction in overall and unused PIVC insertions without any change in appropriate insertions.
The relationship between corporate social responsibility, financial misstatements and SEC enforcement actions
Authors: Tran Nam , O'Sullivan Don 
Published: September 2018

AbstractThis study explores the relationship between corporate social responsibility (CSR), financial misstatements and SEC enforcement actions. We find that firms with higher CSR are less likely to receive SEC enforcement actions for financial misstatements. Drawing on insights from stakeholder theory and the reputational literature, we identify two channels underpinning this relationship: (i) firms with higher CSR are less likely to engage in financial misstatements and (ii) the reputational effect of CSR reduces the likelihood of SEC enforcement actions. We find empirical evidence consistent with both channels.
Quality of life and participation of young adults with a visual impairment aged 18–25 years: comparison with population norms

Published: September 2018

AbstractPurposeTo compare health‐related quality of life and participation of visually impaired young adults with normative groups, and to explore severity of vision loss and its association with participation and quality of life.MethodsYoung adults aged 18–25 years (n = 172) registered at two Dutch low vision rehabilitation organizations completed the Short Form Health Survey (SF‐36), EuroQol‐5 Dimensions (EQ‐5D), Impact on Participation and Autonomy (IPA) and Low Vision Quality of Life questionnaire (LVQOL). EQ‐5D and SF‐36 scores were compared to age‐specific norms. IPA scores were compared to norms of a population having three chronic diseases simultaneously. Linear regression was used to assess the association between severity of vision loss (mild VI, moderate VI and severe VI/blindness), and quality of life and participation.ResultsParticipants scored significantly worse on almost all (sub)scales compared with relevant norms. Effect sizes for the EQ‐5D and SF‐36 (sub)scales were mostly small; moderate and large effect sizes were found for the IPA. Compared to young adults with mild VI, corrected models showed a significant association between having moderate VI and the physical component score of the SF‐36, and between severe VI/blindness and the LVQOL.ConclusionVI has a moderate impact on some aspects of quality of life and a large impact on participation of young adults when compared with relevant normative populations. Severity of vision loss is associated with worse physical functioning and vision‐related quality of life. The results contribute to a better understanding of the impact of VI and might lead to improved low vision services.
