AbstractBACKGROUNDThe fall armyworm (FAW), an invasive pest from the Americas, is rapidly spreading through the Old World, and has recently invaded the Indochinese Peninsula and southern China. In the Americas, FAW migrates from winter-breeding areas in the south into summer-breeding areas throughout North America where it is a major pest of corn. Asian populations are also likely to evolve migrations into the corn-producing regions of eastern China, where they will pose a serious threat to food security.RESULTSTo evaluate the invasion risk in eastern China, the rate of expansion and future migratory range was modelled by a trajectory simulation approach, combined with flight behaviour and meteorological data. Our results predict that FAW will migrate from its new year-round breeding regions into the two main corn-producing regions of eastern China (the North China and Northeast China Plains), via two pathways. The western pathway originates in Myanmar and Yunnan, and FAW will take four migration steps to reach the North China Plain by July. Migration along the eastern pathway from Indochina and southern China progresses faster, with FAW reaching the North China Plain in three steps by June and reaching the Northeast China Plain in July.CONCLUSIONOur results indicate that there is a high risk that FAW will invade the major corn-producing areas of eastern China via two migration pathways, and cause significant impacts to agricultural productivity. Information on migration pathways and timings can be used to inform integrated pest management strategies for this emerging pest.

AbstractSpartina spp. are widely distributed salt marsh plants that have a recent history of hybridization and polyploidization. These evolutionary events have resulted in species with a heightened resilience to hydrocarbon contamination, which could make them an ideal model plant for the phytoremediation/reclamation of contaminated coastal ecosystems. However, it is still unknown if allopolyploidization events also resulted in differences in the plant rhizosphere-associated microbial communities, and if this could improve the plant phytoremediation potential. Here, we grew two parental Spartina species, their hybrid and the resulting allopolyploid in salt marsh sediments that were contaminated or not with phenanthrene, a model tricyclic PAH. The DNA from the rhizosphere soil was extracted and the bacterial 16S rRNA gene and ITS region were amplified and sequenced. Generally, both the presence of phenanthrene and the identity of the plant species had significant influences on the bacterial and fungal community structure, composition and diversity. In particular, the allopolyploid S. anglica, harbored a more diverse bacterial community in its rhizosphere, and relatively higher abundance of various bacterial and fungal taxa. Putative hydrocarbon degraders were significantly more abundant in the rhizosphere soil contaminated with phenanthrene, with the Nocardia genus being significantly more abundant in the rhizosphere of S. anglica. Overall our results are showing that the recent polyploidization events in the Spartina did influence the rhizosphere microbiome, both under normal and contaminated conditions, but more work will be necessary to confirm if these differences result in a higher phytoremediation potential.ImportanceSalt marshes are at the forefront of coastal contamination events caused by marine oil spills. Microbes in these environments play a key role in the natural attenuation of these contamination events, often in association with plant roots. One such plant is the Spartina, which are widely distributed salt marsh plants. Intriguingly, some species of the Spartina show heightened resistance to contamination, which we hypothesized to be due to differences in their microbiota. This was indeed the case, with the most resistant Spartina also showing the most different microbiota. A better understanding of the relationships between the Spartina and their microbiota could improve the coastal oil spill clean-up strategies and provide green alternatives to more traditional physico-chemical approaches.

ABSTRACTPatients born with esophageal atresia (EA) have a 30 times higher prevalence of infantile hypertrophic pyloric stenosis (IHPS). This makes sense from a developmental perspective as both the esophagus and the pyloric sphincter are foregut derived structures. EA and IHPS are variable features in several (monogenetic) syndromes. This, and twin and familial studies, indicates a genetic component for both conditions as single entities. We hypothesized that genetic defects, disturbing foregut morphogenesis, are responsible for this combination of malformations. Non-genetic factors could also contribute, as mice exposed to Adriamycin develop EA andin uterodiethylstilbestrol exposure is associated with EA.We investigated the copy number profiles and protein coding variants of 15 patients with both EA and IHPS. As all parents were unaffected, we first considered dominant(de novo)or recessive inheritance models but could not identify putatively deleterious mutations or recessive variants. We did identify inherited variants in genes either known to be involved in EA or IHPS or important in foregut morphogenesis in all patients. Unfortunately, variant burden analysis did not show a significant difference with unaffected controls. However, the IHPS associated risk SNP rs1933683 had a significantly higher incidence (OR 3.29, p=0.009).Although the genetic variation in likely candidate genes as well as the predisposing locus nearBARX1(rs1933683) suggest a genetic component, it does not fully explain the abnormalities seen in these patients. Therefore, we hypothesize that a combination of high impact genetic, mechanical and environmental factors together can shift the balance to abnormal development.Summary statementInstead of one affected gene, the higher incidence of IHPS in EA patients is more likely the result of multiple (epi)genetic and environmental factors together shifting the balance to disease development.

Published: May 2019

AbstractInduction of stress response geneshsp70andabcb1and Hsp70 protein by cadmium chloride (CdCl2) was explored in amphipod species with different stress adaptation strategies from the Lake Baikal area. Based on lethal concentrations (LC) the sensitivities to CdCl2were ranked (24 hr LC50 – mg/L CdCl2):Gammarus lacustris(1.7) <Eulimnogammarus cyaneus(2.9) <E. verrucosus(8.3) <E. vittatus(18.2). Conjugated dienes indicating lipid peroxidation were significantly increased by 5 mg/L CdCl2(24 hr exposure) only inG. lacustrisandE. cyaneus. Upon treatment with 0.54 – 5.8 mg/L CdCl2hsp70transcript levels were more increased in the toxicologically more sensitive species. Relating the exposure concentrations to LCx values revealed that across the species the increases ofhsp70transcript levels were comparatively low (up to 2.6-fold) up to LC50; at higher LCx valueshsp70induction was more pronounced (up to a 9.1-fold by 5 mg/L CdCl2(≙LC70) inE. cyaneus). In contrast,abcb1inductions did not correspond with CdCl2LCx values across species;abcb1induction was highest (4.7-fold) inE. verrucosusby 5.0 mg/L CdCl2(≙LC45, 24 hr exposure). Induction of stress gene responses by lethal CdCl2concentrations indicates that in the amphipods they are rather insensitive.

SummaryHow neural circuits develop in the human brain has remained almost impossible to study at the neuronal level. Here we investigate human cortical neuron development, plasticity and function, using a mouse/human chimera model in which xenotransplanted human cortical pyramidal neurons integrate as single cells into the mouse cortex. Combined neuronal tracing, electrophysiology, andin vivostructural and functional imaging revealed that the human neurons develop morphologically and functionally following a prolonged developmental timeline, revealing the cell-intrinsic retention of juvenile properties of cortical neurons as an important mechanism underlying human brain neoteny. Following maturation, human neurons transplanted in the visual cortex display tuned responses to visual stimuli that are similar to those of mouse neurons, indicating capacity for physiological synaptic integration of human neurons in mouse cortical circuits. These findings provide new insights into human neuronal development, and open novel experimental avenues for the study of human neuronal function and diseases.Highlights:Coordinated morphological and functional maturation of ESC-derived human cortical neurons transplanted in the mouse cortex.Transplanted neurons display prolonged juvenile features indicative of intrinsic species-specific neoteny.Transplanted neurons develop elaborate dendritic arbors, stable spine patterns and long-term synaptic plasticity.In the visual cortex transplanted neurons display tuned visual responses that resemble those of the host cortical neurons.
Environmental management accounting practices in Australian cotton farming
Authors: Tashakor Shamim , Appuhami Ranjith , Munir Rahat 
Published: May 2019

PurposeThe purpose of this paper is to examine the association between the belief-based factors (attitude, subjective norm (SN) and perceived behavioural control (PBC)) and environmental management accounting (EMA) practices.Design/methodology/approachDrawing on the theory of planned behaviour (TPB), the study develops a structural model and uses partial least squares (PLS) technique to analyse data collected based on a survey of the Australian cotton farmers.FindingsThe findings indicate that while attitude and PBC significantly influence farmers’ intention to adopt EMA practices, SN has a significant indirect influence on EMA practices through farmers’ attitude and PBC. Further, the study reveals that while the intention of more environmentally friendly farmers is largely influenced by attitude and SN, the intention of less environmentally friendly farmers is primarily driven by PBC.Practical implicationsThe study provides important insights into the role of attitude, SN and PBC in motivating farmers towards adopting EMA practices. Such insights could also help farmers in designing effective EMA practices.Originality/valueThis study contributes to very limited EMA literature on TPB by integrating three belief-based factors namely attitude, SN and PBC.
Expansive learning in contemporary construction organisations
Authors: Sackey Enoch , Tuuli Martin , Dainty Andrew 
Published: May 2019

Purpose
The evolving roles of BIM and smart building technologies in the design and management of construction projects often present unexpected events and variabilities, which tend to erode professionals’ prior knowledge authority. The purpose of this paper is to explore how construction organisations can deploy knowledge and adapt to the requisite skills in order to make fitting responses to the ever-evolving technological and organisational transformations to address the prevailing construction challenges.

Design/methodology/approach
The paper opted for an abductive research approach that ensures back-and-forth iterative dialogue between the empirical data and an amalgam of the theoretical proposition towards new understanding of the phenomenon under investigation. A multiple case study method was adopted to collate the empirical data from three separate construction organisations as they transitioned into BIM compliant work processes.

Findings
The study has described new processes that not only mediate existing practices but focus on consistently resolving known tensions and contradictions between prior knowledge and the requirement of the changing work situation. The study also illustrates the cognitive synchronisation of the learning approaches within contemporary work organisations that align well with the merits and utilities entrenched within their niche technological choices.

Research limitations/implications
Due to the chosen research methodology, it is acknowledged that future comparative studies using a much larger quantitative data sample to further elucidate the findings of this paper would be an interesting further step.

Originality/value
The study contributes to construction management literature by providing new insights into expansive learning environments capable of addressing cognitive contradictions and ambiguities inherent in the changing contemporary work patterns in the construction context as a consequence of BIM deployment.

Authors: Olawumi Timothy Oluwatosin , Chan Daniel W.M. 
Published: May 2019

Purpose
The increasing urbanization of the built environment has bolstered the need to promote green Building Information Modeling (BIM) initiative in new construction projects and the rehabilitation of old premises. This study aims to explore and examine the key benefits of the implementation of BIM and sustainability practices in the built environment.

Design/methodology/approach
The study gathered the worldwide perceptions of 220 survey participants from 21 countries which were analyzed using descriptive and inferential analytical methods. The identified individual benefits of green BIM were further categorized into their underlying clusters using factor analysis.

Findings
The key benefits are related to enhancing project efficiency and productivity, ensuring real-time sustainable design and multi-design alternatives, facilitating the selection of sustainable materials and components, together with reducing material wastage and project’s environmental impact, among others. The study analyzed and compared the perceptions of the diverse groups of the respondents as well.

Practical implications
Effective blueprints and insightful recommendations for enhancing the various stakeholders’ capacities to implement green BIM in their construction projects were put forward to achieve the aim of sustainable smart urbanization.

Originality/value
The study identified salient benefits of the adoption of BIM and sustainability practices. The proper integration of these concepts and the execution of the recommended useful strategies by construction stakeholders, policymakers and local authorities will enable the built environment to reap the gains of its implementation.
Materiality: stakeholder accountability choices in hotels’ sustainability reports
Authors: Guix Mireia , Font Xavier , Bonilla-Priego Maria Jesus 
Published: May 2019

PurposeThis paper aims to examine the choices made by the hotel industry about what to include, and who to be accountable to, in their sustainability reports; a process defined as materiality assessment.Design/methodology/approachThe paper is based on the findings of semi-structured interviews with eight sustainability managers (from eight of the world’s 50 largest hotel groups) to explore their understanding of, and use of, materiality and any barriers to its uptake and eight industry sustainability experts to assess the general industry-wide application of materiality.FindingsSustainability managers from large hotel groups are evasive when disclosing their materiality criteria, their decision-making processes and how they aggregate stakeholder feedback; they limit their disclosure to the reporting process. Sustainability managers are disempowered, with limited resources, time, knowledge and skills to apply to materiality assessment. Experts confirm that hotel groups are unsystematic and opaque about their decision-making and how they control their materiality assessments.Practical implicationsMateriality assessment is concealed from the public and may be constructed around business imperatives with high managerial capture. The hospitality industry needs to improve its sustainability reporting by examining how it defines and applies materiality and by addressing the barriers identified, if it is to demonstrate an enduring commitment to sustainability and organisational legitimacy.Originality/valueThis study addresses the limited knowledge of how hotel groups undertake materiality assessments. It identifies gaps in the conception and application of materiality by pinpointing barriers to its uptake and recommending areas in need of further research.
Unlucky for some? Are some hotel rooms and floors really unluckier than others?
Authors: Pratt Stephen , Kwan Pia 
Published: May 2019

PurposeDifferent cultures believe that some numbers are “lucky” and other numbers are “unlucky”. The purpose of this paper is to determine to what extent hotels follow numerological superstitions in their floor and room numbering, if more accidents or complaints occur on unlucky hotel floors compared to other floors and if more accidents or complaints occur in unlucky hotel rooms compared to other rooms.Design/methodology/approachFor the first research objective, an audit of hotels in a particular destination, Hong Kong, is taken capturing the number of floors and rooms on each floor and determining if “unlucky” numbers are used. For the second and third objectives, the accident and complaint database of one upscale hotel in Hong Kong across a five-year period is investigated.FindingsThe authors find that hotels do follow superstitious numbering, with “unlucky” numbers not being included in floor or room numbering. Chinese superstition is more likely to be followed than Western superstition. The non-inclusion of “unlucky” numbers is more likely for hotel floors than for hotel rooms. In the case study hotel, they found no significant differences in the number of accidents and complaints between unlucky and other rooms and floors across the five years of analysis.Originality/valueSuperstitions surrounding numbers can affect decisions made by individuals and businesses and can have significant economic consequences. There is little academic research into how the hotel sector is impacted by numerology superstitions.
Signalling IPO quality through female directors
Authors: Badru Bazeet Olayemi , Ahmad-Zaluki Nurwati A. , Wan-Hussin Wan Nordin 
Published: May 2019

Purpose
The purpose of this paper is to investigate whether or not the presence of female directors at the time of an initial public offering (IPO) can be considered as a signal of IPO quality.

Design/methodology/approach
A sample of 220 Malaysian IPOs over the period of 2005–2015 was used. This study employed the mean regression technique (ordinary least squares and White’s heteroskedasticity-consistent standard errors) and the median regression technique (quantile regression) to examine the signalling power of female directors on the board at the time of an IPO.

Findings
The results show that the presence and proportion of female directors at the time of the IPO have negative effects on IPO initial returns (IR). The negative effects occur at both the conditional mean and the dispersion of IPO IR. These results are robust to endogeneity bias.

Practical implications
The findings of this study suggest that female directors on the board at the time of an IPO can be considered as a desirable signal of IPO quality. As a result, IPO issuers can consider signalling the quality of their IPOs by having female directors on their boards. Likewise, market participants can use female directors as an instrument to value an IPO.

Originality/value
Studies on the impact of female directors on the board have largely been centred on established companies. Thus, this study contributes to the literature by examining the signalling role of women at the time of an IPO, which is considered as a significant milestone in the lifecycle of a company.
Trade credit, firm profitability, and financial constraints
Authors: Hoang Huan Cong , Xiao Qin , Akbar Saeed 
Published: May 2019

PurposeThe purpose of this paper is to investigate the non-linear association between trade credit and profitability of small and medium-sized enterprises (SMEs). Moreover, this paper analyses whether the above relationship varies according to financial constraints of SMEs.Design/methodology/approachThe authors use panel data methodology to conduct investigations for a sample of 1,509 non-financial listed SMEs from nine countries or territories located in the East Asia and Pacific region, namely, China, Vietnam, Malaysia, Thailand, Japan, South Korea, Taiwan, Singapore and Hong Kong, over the period from 2010 to 2016.FindingsThis study indicates that trade credit receivable (TCR) and trade credit payable (TCP) have an invertedU-shaped relationship with SMEs’ profitability, which implies the existence of an optimal trade credit level that balances between costs and benefits to maximize their profitability. This result suggests that managers should try to keep the level of trade credit investment as close to the optimal point as possible to avoid the case that their profitability reduces when they move away from this point. Moreover, this study also finds that the optimal trade credit level is sensitive to the financial constraints of SMEs. In particular, optimal level of more financially constrained firms is lower than that of less financially constrained firms.Originality/valueA number of contributions that this study makes to the existing literature are presented as follows. First, the paper takes account of the possible presence of a concave relationship between trade credit and SMEs’ profitability, largely ignored by the existing empirical literature. Second, it demonstrates this association in terms of both aspects of trade credit, including TCR and TCP. Third, the study investigates the effect of the different level of financial constraints faced by SMEs on the relationship between trade credit and their profitability.
