ABSTRACTThe orchid flower is renowned for complexity of flower organ morphogenesis and has attracted great interest from scientists. The YABBY genes encode plant-specific transcription factors with important roles in vegetative and reproductive development in seed plants.DROOPING LEAF/CRABS CLAW(DL/CRC) orthologs are involved in reproductive organ development (especially carpels) of angiosperms. Orchid gynostemium (the fused organ of the androecium and gynoecium) and ovule development are unique developmental processes. Understanding theDL/CRC-likegenes controlling the developmental program of the gynostemium and ovule could provide accessible information for reproductive organ molecular regulation in orchids. TwoDL/CRC-likegenes, namedPeDL1andPeDL2, were cloned fromPhalaenopsis equestris. The orchid DL/CRC forms a monophyletic clade with two subclades including AshDL, PeDL1 and DcaDL1 in subclade I, and PeDL2 and DcaDL2 in subclade II. The temporal and spatial expression analysis indicatedPeDLgenes are specifically expressed in the gynostemium and at the early stages of ovule development. BothPeDLscould partially complement anArabidopsis crc-1mutant. Transient overexpression ofPeDL1inPhalaenopsisorchids caused abnormal development of ovule and stigmatic cavity of gynostemium. PeDL1, instead of PeDL2, could form a heterodimer with PeCIN8. Paralogue retention and subsequent divergence of the gene sequence ofPeDL1andPeDL2inP. equestrismight result in the differentiation of function and protein behaviors. These results reveal the important roles ofPeDLsinvolved in orchid gynostemium and ovule development and provide new insights for further understanding the molecular mechanisms underlying orchid reproductive organ development.

Published: February 2020

Purpose
Continuous annealing (CA) units usually lack a physical shapemeter; consequently, real-time display and closed-loop control of the strip shape are impossible to achieve.

Design/methodology/approach
A shape model for the CA process is established in this study. Specifically, a virtual shapemeter and closed-loop control system based on the advanced parameter acquisition system and information transmission of CA units are developed in C++ programming language. This system realises real-time dynamic shape display, closed-loop control and shape prediction by collecting raw data of steel coils and parameters during CA.

Findings
Field test results show that the shape predicted by the virtual shapemeter coincides with the measured shape by over 90 per cent, which fully meets the precision requirement of industrial applications.

Originality/value
Moreover, shape quality is effectively improved without increasing hardware investments.

PurposeHistorically, Lean Six Sigma (LSS) implementation has demonstrated a great deal of enhancement to process efficiency, profitability and customer satisfaction. The emerging market pressure for developing better quality, cheaper and greener products invokes a change of view in LSS economical effectiveness. The purpose of this study is to identify under which condition the final output of LSS projects with traditional strategic benefits are more environmentally friendly.Design/methodology/approachTo investigate the choice of different types of LSS projects, the environmental impact under different conditions and the comparison of those conditions, the author developed an analytical mathematical model and analysed four different propositions.FindingsThe final price and production volume were recommended as mediating factors to leverage an LSS project to achieve a greener, customised and finance-oriented outputs.Research limitations/implicationsThis research contributes to existing LSS research and knowledge development via promoting the different perspectives of LSS and environmental sustainability integration.Practical implicationsThis study further enables managers to identify the cut-off point in relation to the production volume and finished prices to leverage the expected financial outputs and environmental impact of the LSS project. This would potentially promote a green LSS project in both implementation and output, alongside its traditional values.Originality/valueThis study uses a modelling approach to identify the conditions under which the actual methodology of the LSS project could be green via less energy consumption with consideration of expected LSS values and outcomes.

Published: February 2020

PurposeThe purpose of this study is to commence the discourse on the non-inclusiveness of the dynamics of reputation within the construction industry by identifying and examining the key product and process drivers of reputation in mega-construction projects.Design/methodology/approachData was collected through an exploratory sequential mixed methods approach which commences with a qualitative study and culminates with a quantitative study to identify product and process drivers of reputation in mega-construction projects.FindingsThe findings suggest that “project quality”, “robust social and environmental sustainability plan”, “project team competence and interpersonal relationship” and “project process efficacy” are the four key drivers influencing the reputation of mega-construction projects.Research limitations/implicationsThe findings of this study are solely based on the perception of UK construction practitioners; therefore, the results may only be considered valid in this context. The identification of these key drivers provides a pathway where stakeholders, professionals and organisations can identify and prioritise critical issues associated with enhancing and sustaining the reputation of mega-construction projects.Originality/valueFindings of this research make a significant contribution to the discourse on the concept of reputation within the construction industry by identifying its specific drivers of reputation.

Abstract

Roots are capable of strong plastic responses to environmental signals, but the extent of such responses in the field is essentially unknown. Here, we aimed to identify interspecific root aggregations and segregations as indicators of plastic responses to the presence of other species. Furthermore, we asked whether aggregations change with heterogeneity in overall root density along soil depth and whether root communities show any relationship to species' functional traits.

We used quantitative real‐Time PCR to estimate root quantities of nine grassland species in soil blocks at a centimetre scale. We combined these estimates with fine‐scale recording of species' positions above‐ground. We used deviations between measured root density and that expected from the relationship to above‐ground species abundance to correct for different chances of individual species to meet due to the non‐random distribution of their individuals. This approach allows us to identify whether species associations below‐ground are due to plastic response of their roots.

We showed that while there were signals of both interspecific aggregation and segregation, prevalence of aggregation over segregation strongly increased with increasing soil depth. In shallow layers, where root density is high and its heterogeneity low, roots are likely to respond to a number of signals which produce both interspecific aggregation and segregation. In contrast, in deeper layers, where root density is low and its heterogeneity high, root distribution is likely to be driven primarily by foraging for resources, producing aggregations. Species composition of the root community did not show any relationship to functional traits (SLA, shoot life span, spreading distance and rooting depth) of the examined species.

Synthesis. The results imply that processes that determine interspecific root associations change at a scale of centimetres which is close to the scale of individual fine roots. They also imply that while root foraging might explain root co‐occurrence under low root density, very different processes determine it when root density is high. Our findings also support the notion that roots, while extremely plastic, may not receive sufficient signals to elicit a response in the field if overall root density is high and homogeneous.

Published: February 2020

AbstractBig data analysis has found applications in many industries due to its ability to turn huge amounts of data into insights for informed business and operational decisions. Advanced data mining techniques have been applied in many sectors of supply chains in the food industry. However, the previous work has mainly focused on the analysis of instrument‐generated data such as those from hyperspectral imaging, spectroscopy, and biometric receptors. The importance of digital text data in the food and nutrition has only recently gained attention due to advancements in big data analytics. The purpose of this review is to provide an overview of the data sources, computational methods, and applications of text data in the food industry. Text mining techniques such as word‐level analysis (e.g., frequency analysis), word association analysis (e.g., network analysis), and advanced techniques (e.g., text classification, text clustering, topic modeling, information retrieval, and sentiment analysis) will be discussed. Applications of text data analysis will be illustrated with respect to food safety and food fraud surveillance, dietary pattern characterization, consumer‐opinion mining, new‐product development, food knowledge discovery, food supply‐chain management, and online food services. The goal is to provide insights for intelligent decision‐making to improve food production, food safety, and human nutrition.

AbstractRed‐fleshed apples are preferred because of their high content of phenolics and antioxidants. In this study, the phenolic characteristics, antioxidant properties, and antihuman cancer cell properties of the four hybrids of Malus sieversii f. niedzwetzkyana (Ledeb.) M. Roem were analyzed. In addition, the antioxidant and anti‐proliferation properties of these apples were measured. Compared to “Fuji” apples, the red‐fleshed apples were rich in phenolic and flavonoid chemicals, ranging from 1.5‐ to 2.6‐fold and 1.4‐ to 2.4‐fold, respectively. In all antioxidant methods (DPPH radical‐scavenging capacity, ABTS radical scavenging activity, ferric reducing antioxidant power, and cell antioxidant capacity), “A38” obtained the highest antioxidant value, whereas “Fuji” got the lowest antioxidant value. The IC50 values ranged from 33.44 (“A38”) to 73.36 mg/mL (“Fuji”) for MCF‐7 and 20.94 (“A38”) to 39.39 mg/mL (“Fuji”) for MAD‐MB‐231. The red‐fleshed “A38” and “Meihong” exhibited higher antioxidant and antiproliferative activities in vitro because of the higher levels of phenolics, and the higher potential for development and utilization value.Practical ApplicationThe phenolic compounds, antioxidant activity, and antiproliferative activity in vitro of four red‐fleshed apple cultivars and one white‐fleshed apple cultivar were compared in this study. This information should assist to give a reasonable evaluation for scientists to breed new cultivars with high phenolics and to exploit the natural polyphenol.

Published: February 2020

AbstractSurveying microbial diversity and function is accomplished by combining complementary molecular tools. Among them, metagenomics is a PCR free approach that contains all genetic information from microbial assemblages and is today performed at a relatively large scale and reasonable cost, mostly based on very short reads. Here, we investigated the potential of metagenomics to provide taxonomic reports of marine microbial eukaryotes. We prepared a curated database with reference sequences of the V4 region of 18S rDNA clustered at 97% similarity and used this database to extract and classify metagenomic reads. More than half of them were unambiguously affiliated to a unique reference whilst the rest could be assigned to a given taxonomic group. The overall diversity reported by metagenomics was similar to that obtained by amplicon sequencing of the V4 and V9 regions of the 18S rRNA gene, although either one or both of these amplicon surveys performed poorly for groups like Excavata, Amoebozoa, Fungi and Haptophyta. We then studied the diversity of picoeukaryotes and nanoeukaryotes using 91 metagenomes from surface down to bathypelagic layers in different oceans, unveiling a clear taxonomic separation between size fractions and depth layers. Finally, we retrieved long rDNA sequences from assembled metagenomes that improved phylogenetic reconstructions of particular groups. Overall, this study shows metagenomics as an excellent resource for taxonomic exploration of marine microbial eukaryotes.

AbstractBiological surveys based on visual identification of the biota are challenging, expensive and time consuming, yet crucial for effective biomonitoring. DNA metabarcoding is a rapidly developing technology that can also facilitate biological surveys. This method involves the use of next generation sequencing technology to determine the community composition of a sample. However, it is uncertain as to what biological substrate should be the primary focus of metabarcoding surveys. This study aims to test multiple sample substrates (soil, scat, plant material and bulk arthropods) to determine what organisms can be detected from each and where they overlap. Samples (n = 200) were collected in the Pilbara (hot desert climate) and Swan Coastal Plain (hot Mediterranean climate) regions of Western Australia. Soil samples yielded little plant or animal DNA, especially in the Pilbara, probably due to conditions not conducive to long‐term preservation. In contrast, scat samples contained the highest overall diversity with 131 plant, vertebrate and invertebrate families detected. Invertebrate and plant sequences were detected in the plant (86 families), pitfall (127 families) and vane trap (126 families) samples. In total, 278 families were recovered from the survey, 217 in the Swan Coastal Plain and 156 in the Pilbara. Aside from soil, 22%–43% of the families detected were unique to the particular substrate, and community composition varied significantly between substrates. These results demonstrate the importance of selecting appropriate metabarcoding substrates when undertaking terrestrial surveys. If the aim is to broadly capture all biota then multiple substrates will be required.
Does emotional intelligence matter to academic work performance? Evidence from business faculties in Australia

Published: February 2020

AbstractUsing data collected through survey questionnaire across 15 universities, we examine the effect of emotional intelligence on academic work performance (in research, teaching and service) in Australian business faculties. We find academics’ ability to use emotion enhances performance across research, teaching and service, while ability to regulate emotion enhances performance for teaching and service only. We also find support for a process‐based model of emotional intelligence in which appraisal of emotion is a necessary antecedent to emotion’s use and regulation. The results have implications for management in appointment decisions and professional development programmes in business/accounting faculties.
The role of serratus anterior plane and pectoral nerves blocks in cardiac surgery, thoracic surgery and trauma: a qualitative systematic review

Published: February 2020

SummarySerratus anterior plane and pectoral nerves blocks are recently described alternatives to established regional anaesthesia techniques in cardiac surgery, thoracic surgery and trauma. We performed a systematic review to establish the current state of evidence for the analgesic role of these fascial plane blocks in these clinical settings. We identified relevant studies by searching multiple databases and trial registries from inception to June 2019. Study heterogeneity prevented meta‐analysis and studies were instead qualitatively summarised and stratified by type of surgery and comparator. We identified 51 studies: nine randomised control trials; 13 cohort studies; 19 case series; and 10 case reports. The majority of randomised controlled trials studied the serratus anterior plane block in thoracotomy or video‐assisted thoracoscopic surgery, with only two investigating pectoral nerves blocks. The evidence in thoracic trauma comprised only case series and reports. Results indicate that single‐injection serratus anterior plane and the pectoral nerves blocks reduce pain scores and opioid consumption compared with systemic analgesia alone in cardiothoracic surgery, cardiac‐related interventional procedures and chest trauma for approximately 6–12 h. The duration of action appears longer than intercostal nerve blocks but may be shorter than thoracic paravertebral blockade. Block duration may be prolonged by a continuous catheter technique with potentially similar results to thoracic epidural analgesia. There were no reported complications and the risk of haemodynamic instability appears to be low. The current evidence, though limited, supports the efficacy and safety of serratus anterior plane and the pectoral nerves blocks as analgesic options in cardiothoracic surgery.

AbstractBackgroundThe objective of the study is to describe temporal trends and regional variations in the use of knee magnetic resonance imaging (MRI), knee arthroscopy and total knee replacement surgery in Australians older than 55 years.MethodsDesign: A retrospective descriptive study using routinely collected administrative data. Main outcome measures: Age‐standardized rates of knee MRI, knee arthroscopy and knee replacement surgery from 2003 to 2017.ResultsKnee MRI rates increased from 216/100 000 in 2003, to 1509/100 000 in 2017 (sevenfold relative increase). Knee arthroscopy rates initially increased from 372/100 000 in 2003 to a maximum of 475/100 000 in 2011, before declining to 283/100 000 in 2017. Knee joint replacement surgery increased from 535/100 000 in 2003 to 840/100 000 in 2017 (57% relative increase). The use of MRI increased in all regions of Australia but to differing extents. Knee arthroscopy rates declined in all regions from 2011, but to differing extents. Knee joint replacement surgery increased at roughly the same rate across Australia.ConclusionKnee arthroscopy rates increased before declining modestly in more recent years, most likely in response to evidence against its effectiveness. Knee MRI rates have continued to increase despite consistent recommendations against their routine use in the evaluation of knee pain. Future research could investigate potential drivers of the increased use of MRI, and of the continued use of arthroscopy. Further exploration of the extent to which either procedure explains the increase in numbers of knee joint replacements is also warranted.

AbstractAimLittle is known about infant‐directed speech addressed to preterm infants. The current study investigated the association between changes in preterm infant behavioural states and acoustical qualities of both maternal and paternal infant‐directed speech.MethodsThe mothers and fathers of 11 preterm infants participated in the study. Parents in turn were asked to talk freely to their infant over a 5‐minute period. A total of 72 audio sequences were selected and analysed as a function of the behavioural states.ResultsAcoustic analysis showed that the vocal qualities of both fathers' and mothers' speech were influenced by infant behaviour. Parental infant‐directed speech was characterised by higher loudness and spectral related parameters when preterm infants were sleeping, or transiting from one state to another, than when they were awake. Furthermore, loudness and spectral flux were higher in maternal speech than in paternal speech and fathers used higher pitch, jitter and shimmer when they saw their preterm infant in an awake state, demonstrating that alertness in infants modulates the father's voice.ConclusionMore research is needed to know whether other social partners' vocal qualities may also be related to infant behavioural state as such findings would have implications for clinical practice.
