AbstractSupra-annually synchronized flowering events occurring in tropical forests in Southeast Asia, known as general flowering (GF), are “spectacular and mysterious” forest events. Recently, studies that combined novel molecular techniques and model-based theoretical approaches suggested that cool temperature and drought synergistically drove GF. Although the novel approaches advanced our understanding of GF, it is usually difficult to know whether the mathematical formulation reasonably well represents the complex and dynamic processes involved in GF. In the present study, we collected a 17-year set of community-wide phenology data during 1993 to 2011 from Lambir Hills National Park in Borneo, Malaysia, and analyzed it using a model-free approach, empirical dynamic modeling (EDM), that does not rely on specific assumptions about the underlying mechanisms, to overcome and complement the previous limitations. By using EDM, we found that GF in the forest in Lambir Hills National Park is synergistically driven by cool air temperature and drought, which is consistent with the previous studies. Also, we found that cumulative meteorological variables, rather than instantaneous values, drive GF with delayed effects, which is also consistent with the previous studies. Interestingly, the present study showed that effects of cumulative meteorological variables on GF changed through time, which implies that the relationship between GF and meteorological variables may be influenced by other factors such as plant/soil nutrient resource dynamics. Future studies integrating novel mathematical/statistical frameworks, long-term and large spatial scale ecosystem monitoring and molecular phenology data are promising for better understanding and fore-casting of GF events in tropical forests in Southeast Asia.
Timing seed germination under changing salinity: a key role of the ERECTA receptor-kinases

Published: March 2019

AbstractAppropriate timing of seed germination is crucial for the survival and propagation of plants, and for crop yield, especially in environments prone to salinity or drought. Yet, how exactly seeds perceive changes in soil conditions and integrate them to trigger germination remains elusive, especially once non-dormant. Here we report that the Arabidopsis ERECTA (ER), ERECTA-LIKE1 (ERL1) and ERECTA-LIKE2 (ERL2) leucine-rich-repeat receptor-like kinases synergistically regulate germination and its sensitivity to salinity and osmotic stress. Loss of ER alone, or in combination with ERL1 and/or ERL2 slows down the initiation of germination and its progression to completion, or arrests it altogether until better conditions return. That function is maternally controlled via the embryo surrounding tissues, primarily the properties of the seed coat determined during seed development on the mother plant, that relate to both seed coat expansion and subsequent differentiation, particularly the formation of its mucilage. Salt-hypersensitive er, er erl1, er erl2 and triple mutant seeds also exhibit increased sensitivity to ABA during germination, and under salinity show an enhanced upregulation of the germination repressors and inducers of dormancy ABA-insensitive-3, ABA-insensitive-5, DELLA encoding RGL2 and Delay-Of-Germination-1. These findings reveal a novel role of the ERECTA kinases in the sensing of conditions at the seed surface and the integration of developmental and stress signalling pathways in seeds. They also open novel avenues for the genetic improvement of plant adaptation to harsh soils.HighlightThe ERECTA family of receptor-kinases regulates seed germination under salinity, through mucilage-mediated sensing of conditions at the seed surface, and interaction with secondary dormancy mechanisms.
The transcription factor Odd-paired regulates temporal identity in transit-amplifying neural progenitors via an incoherent feed-forward loop
Authors: Abdusselamoglu Merve Deniz , Eroglu Elif , Burkard Thomas R. , Knoblich Juergen A. 
Published: March 2019

AbstractNeural progenitors undergo temporal patterning to generate diverse neurons in a chronological order. This process is well-studied in the developing Drosophila brain and conserved in mammals. During larval stages, intermediate neural progenitors (INPs) serially express Dichaete (D), grainyhead (Grh) and eyeless (Ey/Pax6), but how the transitions are regulated is not precisely understood. Here, we developed a method to isolate transcriptomes of INPs in their distinct temporal states to identify a complete set of temporal patterning factors. Our analysis identifies odd-paired (opa), as a key regulator of temporal patterning. Temporal patterning is initiated when the SWI/SNF complex component Osa induces D and its repressor Opa at the same time but with distinct kinetics. Then, high Opa levels repress D to allow Grh transcription and progress to the next temporal state. We propose that Osa and its target genes opa and D form an incoherent feedforward loop (FFL) and a new mechanism allowing the successive expression of temporal identities.
Co-occurrence of organic and inorganic N sources influences asparagine uptake and internal amino acid profiles in white clover
Authors: Czaban Weronika , Rasmussen Jim 
Published: March 2019

AbstractDirect plant uptake of organic nitrogen (N) is important for plant N nutrition, but we lack knowledge of how the concentration of external N forms (organic and inorganic) -influence organic N uptake and plant N status. We investigated the uptake of the amino acid asparagine (Asn) in white clover in the presence of different nitrate (NO3-), Asn, and total N concentrations. White clover seedlings were for one week exposed to combinations of NO3-(3-30 µmol N kg-1sand DW) and Asn (3-30 µmol N kg-1sand DW), where after the Asn uptake rate was determined by addition of13C4-Asn. Shoot and root Asn content and amino acid profiles were also analyzed. Increasing external NO3-and total N concentrations decreased13C4-Asn uptake rates and internal clover Asn content. Furthermore, total N affected clover amino acid profiles from non-essential amino acids at low N doses to the dominance of essential amino acids at increasing N doses. Asn uptake rate in white clover is reduced by increasing inorganic N, but not by increasing organic N concentrations. Furthermore, plant amino acid profiles are likely to be a more sensitive indicator of N supply and descriptor of the N status.

AbstractOBJECTIVEErythropoietin (EPO) is a clinically available hematopoietic cytokine. The aim of this study was to evaluate the effect of EPO on a rat model of cervical cord compression myelopathy and to explore the possibility of its use as a pharmacological treatment.METHODSTo produce the chronic cervical cord compression model, thin polyurethane sheets were implanted under the C5-C6 laminae of rats and gradually expanded due to water absorption. In this model, motor functions significantly declined from 7 weeks after surgery. Based on the result, EPO administration was started 8 weeks after surgery. Motor function as seen with rotarod performance and grip strength was measured 16 weeks after surgery, and then motor neurons were stained with H-E and NeuN staining, and counted. Apoptotic cell death was assessed with terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick end labeling (TUNEL) staining. To assess transfer of EPO into spinal cord tissue, the EPO level in spinal cord tissue was measured with an enzyme-linked immunosorbent assay for each group after subcutaneous injection of EPO.RESULTSHigh-dose EPO (5000 IU/kg) administered from 8 weeks after surgery markedly restored and maintained motor function in the Compression groups (P < 0.01). EPO significantly prevented loss of motor neurons in the anterior horn (P < 0.05) and significantly decreased the number of TUNEL-positive apoptotic cells (P < 0.05). The EPO level in spinal cord tissue was significantly higher in the High-dose EPO group than other groups.CONCLUSIONSEPO improves motor function in rats with progressive chronic compression myelopathy. EPO protects anterior horn motor neurons and inhibits neuronal cell apoptosis in spinal cord compression. The neuroprotective effects can be produced through transfer of EPO into spinal cord tissue. These findings suggest that EPO has high potential as a treatment for developing compression myelopathy.
CSR website disclosure: the influence of the upper echelons
Authors: Everaert Patricia , Bouten Lies , Baele Annelien 
Published: March 2019

PurposeUsing upper echelons theory (UET), the purpose of this paper is to unravel the influence of a CEO’s ethical ideology on the presence of corporate social responsibility (CSR) disclosure on corporate websites. It also considers the CEO’s perception of the importance of CSR (i.e. the extent of the CEO’s detachment from the stockholder-oriented logic and attachment to the stakeholder-oriented logic).Design/methodology/approachFirst, a survey was sent to CEOs of large unlisted Belgian companies. Its intention was to assess CEOs’ ethical ideology along the idealism and relativism dimensions and their perceptions on the importance of CSR (PRESOR-detachment-from-stockholder view; PRESOR-attachment-to-stakeholder view), and to gather some demographics. Second, a content analysis of corporate websites was conducted so as to classify companies as being either CSR disclosing or non-disclosing. Third, the annual accounts of these corporations were investigated and follow-up phone calls were conducted to obtain data on managerial discretion (MD).FindingsCEOs’ ethical ideology influences the degree to which they detach from the stockholder-oriented logic and attach to the stakeholder-oriented logic. Moreover, when MD is high, the degree of these CEOs’ attachment to the stakeholder-oriented logic is the factor that influences the presence of CSR disclosure on their corporate websites. Finally, CEO’s idealism indirectly influences the presence of CSR disclosure through the effect of idealism on the degree to which CEOs attach to the stakeholder-oriented logic.Originality/valueThis paper shows that, when MD is high, CEOs’ values and perceptions influence CSR disclosure decisions. This study thereby enhances our knowledge regarding the internal drivers of CSR disclosure practices and offers UET as a lens through which the importance of CEOs’ personal characteristics in the decision-making process might be further explored.
Australian corporate political donation disclosures
Authors: Tello Edward , Hazelton James , Leong Shane Vincent 
Published: March 2019

Purpose
A primary tool for managing the democratic risks posed by political donations is disclosure. In Australia, corporate donations are disclosed in government databases. Despite the potential accountability benefits, corporations are not, however, required to report this information in their annual or stand-alone reports. The purpose of this paper is to investigate the quantity and quality of voluntary reporting and seek to add to the nascent theoretical understanding of voluntary corporate political donations.

Design/methodology/approach
Corporate donors were obtained from the Australian Electoral Commission database. Annual and stand-alone reports were analysed to determine the quantity and quality of voluntary disclosures and compared to O’Donovan’s (2002) legitimation disclosure response matrix.

Findings
Of those companies with available reports, only 25 per cent reported any donation information. Longitudinal results show neither a robust increase in disclosure levels over time, nor a clear relationship between donation activity and disclosure. The findings support a legitimation tactic being applied to political donation disclosures.

Practical implications
The findings suggest that disclosure of political donations in corporate reports should be mandatory. Such reporting could facilitate aligning shareholder and citizen interests; aligning managerial and firm interests and closing disclosure loopholes.

Originality/value
The study extends the literature by evaluating donation disclosures by companies known to have made donations, considering time-series data and theorising the findings.
Semiconductor properties of passive film and corrosion resistance of 2205 duplex stainless steel joint welded by laser hybrid welding
Authors: Yi Guo , Xu Junhua , Zheng Chuanbo 
Published: March 2019

Purpose
There are obvious differences in corrosion resistance of different 2205 welding joints with different ratios of austenite and ferrite, from the top to the bottom, the austenite content decreased gradually while the ferrite increased. In each region of welded joint, the pitting resistance number of ferrite is higher than that of austenite; pitting corrosion is more likely to occur in austenite phase first on the top region of the weld and in the secondary phase precipitates on the other regions of the weld. The fluctuation of the ratio of austenite and ferrite has a great influence on performance of passive film in 3.5 per cent NaCl solution.

Design/methodology/approach
To study the corrosion behavior of welded joint, the samples were obtained by laser hybrid welding. Pitting corrosion was studied in different area of welded joint. The Mott–Schottky curves of welded joints were measured to study the passive film on the different welded joint area.

Findings
Due to the difference of heat input and the limit of filler depth of the wire, the microstructure of duplex stainless steel laser welding joint has obvious difference in the thickness direction. In addition, there will be harmful secondary phase (such as chromium nitride and σphase) precipitates in the lower part of the joint. For the welded joint, the corrosion resistance decreases with the increase in the difference of the microstructure. Pitting corrosion usually takes the two phases as the nucleation point and grows up. The surface of 2205 duplex stainless steel laser hybrid welding joint cannot form a complete passive film in 3.5 per cent NaCl solution, and the more the ratios of austenite and ferrite deviate from equilibrium position (50:50), the worse the performance of passive film is.

Originality/value
In this paper, the authors attempt to establish the correlation between the semiconductor electronic properties of passive film and the difference of microstructures and the component in a joint welded by laser hybrid welding. The effect of passive film on the corrosion resistance of the weld was further investigated.

Adaptation of international sustainability rating tools to Bahrain
Authors: Al Khalifa Fay Abdulla 
Published: March 2019

Purpose
The damage humans caused to the environment post the industrial revolution fostered developing sustainability-rating systems – a number of evaluation instruments that focus on various factors to evaluate buildings and small-scale urban developments. Nevertheless, no buildings are certified in Bahrain, the environmentally challenged country in the Arabian Gulf. The paper aims to discuss these issues.

Design/methodology/approach
This study assesses 11 sustainability-rating systems: LEED, Green Globes, BREEAM, DGNB, SBTool, WELL, CASBEE, Green Star, HQE, GSAS and the Pearl Rating System (PRS). These were selected because of their international applicability, popularity and importance. The study adopts a system of criteria using a comparative review and cross-comparisons to draw conclusions on the compliance of the selected systems to the Bahraini context and assesses the need and importance of a customised sustainability-rating tool.

Findings
The study concluded that LEED is the most comprehensive, international and versatile sustainability-rating system. It is also the most popular. Nevertheless, the PRS is the most relevant to the Bahraini context and is the easiest to access.

Originality/value
This paper provides a deep understanding of sustainability-rating tools and introduces a methodology of comparison that can be used as a reference when choosing between tools.
Adoption of green practices throughout the supply chain: an empirical investigation
Authors: Choudhary Kailash , Sangwan Kuldip Singh 
Published: March 2019

Purpose
There is a dichotomy in the actual and expected environmental performances of the Indian enterprises even though the Indian enterprises have aligned their businesses with intended nationally determined contributions (INDC) targets. The purpose of this paper is to analyze the supply chain of Indian enterprises to understand influences to adopt green practices throughout the supply chains, and how these green practices influence economic, operational and environmental performances to reveal the underlying currents explaining difference in actual and expected performance.

Design/methodology/approach
Five research propositions are developed based on the existing literature. Data are collected from 233 ceramic enterprises in India. Exploratory factor analysis has been done to test construct validity and correlation. Confirmatory factor analysis is used to check unidimensionality of constructs. Structural equation modeling is used to test the strength and direction of the relations between the constructs and to develop the model.

Findings
The findings of the study suggest that the Indian companies have aligned their businesses with INDC targets but they have not adopted the green practices in inbound and outbound supply chains; therefore, the actual environmental performance is not as expected. Other major finding is that the enterprise and government are not focusing on the informative pressure and instead the focus is on coercive techniques which are not yielding positive results. The statistical results show that the adoption of green practices led to the improvements in environmental and operational performances but reduction in economic performance.

Originality/value
This paper has analyzed green supply chain management pressure, practice and performance measure for Indian ceramic enterprises and proposed a structural model with their interrelation.

Authors: Mukhi Umesh , Quental Camilla 
Published: March 2019

Purpose
The 17 United Nations sustainable development goals (SDGs) represent a powerful guide to foster actions to achieve a more sustainable planet. This paper aims to analyze the challenges and opportunities of SDGs based on an interview conducted with climate scientist Dr Carlos Nobre. In this interview, Nobre addresses the opportunities and challenges of the SDGs. More broadly, the aim is to raise awareness among scholars, policymakers and citizens about what is considered to be the most important societal questions of the times.

Design/methodology/approach
The authors analyze the interview conducted with this prominent and experienced climate scientist through academic lenses of interpretive approach. Further, the authors are bringing important reflections from this interview and linking it to Rasche et al.’s (2017) model, which cut across different levels and take into consideration the individual, organizational and societal levels in the relationship for SDG.

Findings
The interview reveals that all SDGs are interlinked and are of equal importance. However, the authors discuss three important challenges and opportunities addressed by Dr Nobre regarding the implementation of the SDGs. These are education, climate change and peace.

Originality/value
To better understand the challenges and opportunities of SDGs and how to act on them as citizens and management scholars, the authors believe that it is imperative to consider the viewpoint of climate scientists who, through their knowledge on earth science, have been contributing globally to the United Nations SDGs agenda at global and local levels. In this paper, the authors analyze the challenges and opportunities of SDGs based on an interview conducted with climate scientist Dr Carlos Nobre.
