Can employee's boundary-spanning behavior exactly promote innovation performance? The roles of creative ideas generation and team task interdependence
Authors: Zhang Qiuping , Li Jin 
Published: December 2020

PurposeThe complex and changeable working environment makes individual cross-boundary activities inevitable. Yet, how employee's boundary-spanning behavior (BSB) stimulates innovation performance remains to be further explored. This study aims to analyze the intermediary mechanism and boundary conditions between employee's BSB and innovation performance based on knowledge integration theory.Design/methodology/approachThe authors collected data in two waves (July and August 2017) and from two hierarchical levels (from the final sample of 286 employees and their 29 direct supervisors) within ten manufacturing firms located in Nanjing and Anhui, China.FindingsThe results indicate that creative ideas generation mediates the relationship between employee's BSB and innovation performance. Moreover, employees with higher levels of team task interdependence (TTI) lead to a stronger relationship between ideas generation and innovation performance compared to lower levels of TTI (positively moderates the second stage of mediation).Practical implicationsBy verifying the key effects of ideas generation and TTI between employee's BSB and innovation performance, the findings of this study provide practical guidance for enterprises to improve the efficiency of employee's BSB.Originality/valueFirst, the authors use knowledge integration theory (Grant, 1996a) to deduce the formation process of the mechanism between employee's BSB and his/her innovation results, which clearly shows the driving forces and integral power of the formation process within an individual knowledge integrating system. The authors’ second contribution is further exploring the conditions under which engaging innovative ideas generated by the integration of employee's BSB is more likely to lead to ideas for implementation by examining TTI as a team-level moderator.

Published: December 2020

PurposeThis study uses a critically acclaimed digital game as an instructional tool to explore the role of emotional design elements on psychological flow and perceived learning.Design/methodology/approachThe authors employ transportation theory to generate a set of antecedents of psychological flow and the theory of flow to connect the gaming experience to positive learning outcomes. The authors investigate the subjective learning experience of players with the use of a psychometric survey, and the authors employ structural equation modelling (SEM) to unearth the direct as well as the indirect effects amongst narrative, aesthetics, flow and learning outcomes.FindingsThe findings of this study demonstrate that narrative and aesthetics in serious games positively influence the perceived learning by facilitating a state of psychological flow.Research limitations/implicationsThis study contributes to better understanding and theorizing the role of narrative and aesthetics on learning outcomes in the context of serious games.Practical implicationsThe findings of this study bear valuable implications for the design of serious games as they highlight the importance of elements often disregarded as not directly related to the learning process and are typically absent from the design of serious games.Originality/valuePrior studies have identified aesthetics and narratives as design elements that contribute to the perceived enjoyment of a game; this study empirically investigates the role of narratives and aesthetics in enhancing perceived learning through psychological flow.
Student and staff expectations and experiences of a UK–China Transnational Education collaboration
Authors: Rowley Martin , Skipper Yvonne 
Published: December 2020

PurposeThis study reports the results of a survey of teaching staff in the UK and China and two cohorts of Chinese students. We explored perceptions of a Transnational Education (TNE) course taught by UK teachers at a Chinese university to ascertain similarities and differences in perceptions and to help inform future TNE design and provision.Design/methodology/approachTeachers in the UK (N = 10) and Chinese University (N = 20) and two cohorts of Chinese students (N = 102) completed questionnaires about their perceptions of the collaboration, including why they thought the university had developed the course and the benefits and risks of the course. They were also asked why they personally or why they thought the students had enrolled in the course. Questions were a mix of forced choice and open response formats.FindingsPrior to the course commencing, differences were identified between UK and Chinese teachers in their perception of the risks and benefits of the course and the challenges students might face. Differences were also seen in teachers' and students' views about why students enrolled and their expectations about the course. The TNE is no longer running and many of the reasons for this were identified by our participants before the course had begun.Originality/valueThis suggests the importance of engaging with various stakeholders in the setup of TNE to ensure a close match between staff, student and institutional expectations of the course. This is likely to increase the likelihood of success of such programmes.
Food waste reduction in supply chains through innovations: a review
Authors: Aramyan Lusine , Grainger Matthew , Logatcheva Katja , Piras Simone , Setti Marco , Stewart Gavin , Vittuari Matteo 
Published: December 2020

Purpose
Agri-food supply chains are facing a number of challenges, which cause inefficiencies resulting in the waste of natural and economic resources, and in negative environmental and social impacts. Food waste (FW) is a result of such inefficiencies and supply chain actors search for economically viable innovations to prevent and reduce it. This study aims to analyse the drivers and the barriers that affect the decision of supply chain operators to adopt innovations (technological – TI, organisational – OI and marketing – MI) to reduce FW.

Design/methodology/approach
The analysis was carried out using a four-step approach that included: a literature review to identify factors affecting the decision to adopt innovations; analysis of FW drivers and reduction possibilities along agri-food supply chains through innovations; mapping the results of Steps 1 and 2 and deriving conclusions regarding the factors affecting the adoption of innovations to reduce and prevent FW.

Findings
Results show that different types of innovations have a high potential in reducing and preventing FW along the supply chain; however, they still must be economically feasible to be adopted by decision makers in the food supply chain. TI, OI and MI are often interrelated and can trigger each other. When it comes to a combination of different types of innovation to reduce and prevent FW, a good example of combining TI, OI and MI may be observed in the retail sector in Europe. Here, innovative smartphone apps (TI) to promote the sale of products nearing their expiration dates (OI in terms of organising the sales differently and MI in terms of marketing it differently) were developed and adopted via different retailing channels, leading to the creation of a new business model.

Practical implications
This study analyses the drivers of FW generation together with the factors affecting the decision to adopt innovations to reduce it and provides solutions to supply chain operators to prevent and reduce FW through different types of innovations.

Originality/value
Literature has not systematically addressed innovations aiming at the reduction of FW yet. This paper provides a comprehensive literature review of the determinants of innovation adoption and offers a novel view on the problem of FW reduction by means of innovation, by linking factors affecting the decision to innovate with FW drivers.

Published: December 2020

SummaryThe removal of unwanted genetic material is a key aspect in many synthetic biology efforts and often requires preliminary knowledge of which genomic regions are dispensable. Typically, these efforts are guided by transposon mutagenesis studies, coupled to deepsequencing (TnSeq) to identify insertion points and gene essentiality. However, epistatic interactions can cause unforeseen changes in essentiality after the deletion of a gene, leading to the redundancy of these essentiality maps. Here, we present LoxTnSeq, a new methodology to generate and catalogue libraries of genome reduction mutants. LoxTnSeq combines random integration of lox sites by transposon mutagenesis, and the generation of mutants via Cre recombinase, catalogued via deep sequencing. When LoxTnSeq was applied to the naturally genome reduced bacterium Mycoplasma pneumoniae, we obtained a mutant pool containing 285 unique deletions. These deletions spanned from > 50 bp to 28 Kb, which represents 21% of the total genome. LoxTnSeq also highlighted large regions of non‐essential genes that could be removed simultaneously, and other non‐essential regions that could not, providing a guide for future genome reductions.

Published: December 2020

AbstractPassion fruit, native to tropical America, is an agriculturally, economically and ornamentally important fruit plant that is well known for its acid pulp, rich aroma and distinctive flavour. Here, we present a chromosome‐level genome assembly of passion fruit by incorporating PacBio long HiFi reads and Hi‐C technology. The assembled reference genome is 1.28 Gb size with a scaffold N50 of 126.4 Mb and 99.22% sequences anchored onto nine pseudochromosomes. This genome is highly repetitive, accounting for 86.61% of the assembled genome. A total of 39,309 protein‐coding genes were predicted with 93.48% of those being functionally annotated in the public databases. Genome evolution analysis revealed a core eudicot‐common γ whole‐genome triplication event and a more recent whole‐genome duplication event, possibly contributing to the expansion of certain gene families. The 33 rapidly expanded gene families were significantly enriched in the pathways of isoflavone biosynthesis, galactose metabolism, diterpene biosynthesis and fatty acid metabolism, which might be responsible for the formation of featured flavours in the passion fruit. Transcriptome analysis revealed that genes related to ester and ethylene biosynthesis were significantly upregulated in the mature fruit and the expression levels of those genes were consistent with the accumulation of volatile lipid compounds. The passion fruit genome analysis improves our understanding of the genome evolution of this species and sheds new lights into the molecular mechanism of aroma biosynthesis in passion fruit.
Cathodoluminescence and Trace Element Composition of Scheelite from the Middle‐Lower Yangtze River Metallogenic Belt (MLYB): Implications for Mineralization and Exploration

Published: December 2020

AbstractThe Middle–Lower Yangtze River Metallogenic Belt (MLYB) is known to contain abundant copper and iron porphyry‐skarn deposits, with an increasing number of tungsten deposits and scheelite in Fe–Cu deposits being discovered in the MLYB during recent decades. The ore genesis of the newly‐discovered tungsten mineralization in the MLYB is poorly understood. We investigate four sets of scheelite samples from tungsten, iron and copper deposits, using CL imaging and LA–ICP–MS techniques to reveal internal zonation patterns and trace element compositions. The REE distribution patterns of four studied deposits show varying degrees of LREE enrichment with negative Eu anomalies. The oxygen fugacity of ore‐forming fluid increased in Donggushan, while the oxygen fugacity of ore‐forming fluid decreased in Ruanjiawan, Guilinzheng and Gaojiabang. The scheelites from the Donggushan, Ruanjiawan, Guilinzheng and Gaojiabang deposits show enrichment in LREEs and HFSE, with Nb/La ratios ranging from 1.217 to 52.455, indicating that the four tungsten deposits are enriched in the volatile fluorine. A plot of (La/Lu)N versus Mo/δEu can be used to distinguish quartz vein type, porphyry and skarn tungsten deposits. This study demonstrates that scheelite grains can be used to infer tungsten mineralization and are effective in identifying magmatic types of tungsten deposits in prospective mining sites.

The sediment profile from Lake Gościąż in central Poland comprises a continuous, seasonally resolved and exceptionally well‐preserved archive of the Younger Dryas (YD) climate variation. This provides a unique opportunity for detailed investigation of lake system responses during periods of rapid climate cooling (YD onset) and warming (YD termination). The new varve record of Lake Gościąż presented here spans 1662 years from the late Allerød (AL) to the early Preboreal (PB). Microscopic varve counting provides an independent chronology with a YD duration of 1149+14/–22 years, which confirms previous results of 1140±40 years. We link stable oxygen isotopes and chironomid‐based air temperature reconstructions with the response of various geochemical and varve microfacies proxies especially focusing on the onset and termination of the YD. Cooling at the YD onset lasted ~180 years, which is about a century longer than the terminal warming that was completed in ~70 years. During the AL/YD transition, environmental proxy data lagged the onset of cooling by ~90 years and revealed an increase of lake productivity and internal lake re‐suspension as well as slightly higher detrital sediment input. In contrast, rapid warming and environmental changes during the YD/PB transition occurred simultaneously. However, initial changes such as declining diatom deposition and detrital input occurred already a few centuries before the rapid warming at the YD/PB transition. These environmental changes likely reflect a gradual increase in summer air temperatures already during the YD. Our data indicate complex and differing environmental responses to the major climate changes related to the YD, which involve different proxy sensitivities and threshold processes.
Predictor complexity and feature selection affect Maxent model transferability: Evidence from global freshwater invasive species
Authors: Low Bi Wei , Zeng Yiwen , Tan Heok Hui , Yeo Darren C.J. 
Published: December 2020

AbstractAimEcological niche models (ENMs) are widely used to address urgent real‐world problems such as climate change effects or invasive species; however, the generality of models when projected through space and/or time, that is transferability, remains a key challenge. Here, we explored the effects of complex predictors and feature selection on ENM transferability in a widely employed algorithm, Maxent, using five globally invasive freshwater species as case studies.LocationGlobal.MethodsWe modelled the global distributions of five notorious freshwater invasive species (African sharptooth catfish Clarias gariepinus, Mozambique tilapia Oreochromis mossambicus, American bullfrog Lithobates catesbeianus, red swamp crayfish Procambarus clarkii, and Australian redclaw crayfish Cherax quadricarinatus), using three predictor datasets of varying complexities derived from two commonly used climatic data sources (WorldClim and IPCC) and three methods of model tuning that differentially incorporated feature selection. Spatially explicit transferability assessments were then conducted using a suite of evaluation metrics previously used to quantify Maxent model performance.ResultsWe show that in the absence of detailed biological knowledge of focal species, simpler predictor datasets produce models that are more accurate than those calibrated using comprehensive “bioclimatic” datasets. Additionally, we find that tuning models for both optimal regularization parameters as well as feature‐class combinations led to the greatest increases in transferability and geographic niche conservatism. Results indicate a tenuous link between model transferability and Akaike's information criterion corrected for small sample sizes (AICc), suggesting that the indiscriminate use of AICc as an estimate of model parsimony may lead to erratic model performance.Main conclusionsOur findings demonstrate that methodological considerations can drastically affect the reliability of spatial and possibly temporal projections, which has severe implications when ENMs are used to infer species’ niches, and quantify ecological or evolutionary change across impacted landscapes.
Are biologics more effective than corticosteroids for intra‐articular treatment of osteoarthritis?
Authors: White G. F. , Gómez Álvarez C. B. , Lewis R. 
Published: December 2020

SummaryIntra‐articular corticosteroids are an effective treatment for equine osteoarthritis, however, there is increasing evidence for the effectiveness of other treatments such as biologics. Whilst current evidence does support biologics and their use in patients diagnosed with osteoarthritis, there remains to be a lack of evidence regarding their long‐term outcomes and the efficacy of their use as a treatment, especially when compared to corticosteroids. This paper reviewed the evidence comparing intra‐articular corticosteroids and biologics in the treatment of equine osteoarthritis and found that whilst they are both effective treatments, more evidence directly comparing them is required.

Published: December 2020

AbstractBased on plant occurrence data covering all parts of Germany, we investigated changes in the distribution of 2136 plant species between 1960 and 2017. We analyzed 29 million occurrence records over an area of ~350,000 km2on a 5 × 5 km grid using temporal and spatiotemporal models and accounting for sampling bias. Since the 1960s, more than 70% of investigated plant species showed declines in nationwide occurrence. Archaeophytes (species introduced before 1492) most strongly declined but also native plant species experienced severe declines. In contrast, neophytes (species introduced after 1492) increased in their nationwide occurrence but not homogeneously throughout the country. Our analysis suggests that the strongest declines in native species already happened in the 1960s–1980s, a time frame in which often few data exist. Increases in neophytic species were strongest in the 1990s and 2010s. Overall, the increase in neophytes did not compensate for the loss of other species, resulting in a decrease in mean grid cell species richness of −1.9% per decade. The decline in plant biodiversity is a widespread phenomenon occurring in different habitats and geographic regions. It is likely that this decline has major repercussions on ecosystem functioning and overall biodiversity, potentially with cascading effects across trophic levels. The approach used in this study is transferable to other large‐scale trend analyses using heterogeneous occurrence data.

Published: December 2020

AimThis study aimed to explore the association between socioeconomic status and urinary incontinence (UI).MethodsWe used data from the three waves of the Taiwan Longitudinal Study on Aging. This study included 2458 women and 2866 men aged ≥50 years. We used logistic random effects models to examine the associations of interest, adjusting for demographics, health‐related behaviors, disability, number of health conditions and prostate problems for men and numbers of children for women.ResultsIn adjusted analysis, women with secondary education least frequently reported UI compared with women with no formal education (adjusted odds ratio [AOR] 0.41, 95% confidence interval [95% CI] 0.22–0.79). Those with severe economic hardships (vs those with no economic hardships) had an increased risk of UI among men and women (AOR 2.71, 95% CI 1.72–4.25 and AOR 1.94, 95% CI 1.31–2.88, respectively). Compared with men doing mentally demanding jobs, service workers/salesperson and retired men were more prone to UI (AOR 2.67, 95% CI 1.14–6.36 and AOR 2.41, 95% CI 1.19–4.87, respectively). Further analysis showed that the associations of economic hardship with UI were attenuated when adjusting for access to healthcare.ConclusionNo formal education in women and severe economic hardship in both the sexes were associated with an increased risk of UI among middle‐aged and older persons. The disparities should be taken into account in interventions for prevention, treatment and management of UI. Geriatr Gerontol Int 2021; 21: 245–253.
Down‐regulation of EOMES drives T‐cell exhaustion via abolishing EOMES‐mediated repression of inhibitory receptors of T cells in liver cancer

Published: December 2020

AbstractT‐cell exhaustion is one of the hallmarks in cancer, but the mechanisms underlying T‐cell dysregulation remains unclear. Here, we reported that down‐regulation of transcription factor EOMES contributed to increased levels of inhibitory receptors in T cell among the tumour tissues and resulted in the poor prognosis of hepatocellular carcinoma (HCC). By analysing the correlation between EOMES in tumour‐infiltrating T cells and the clinical features, we demonstrated that the EOMES was related to the advanced stage and poor prognosis of HCC. Further mechanistic studies revealed that the EOMES mainly expressed in the CD8+ T cells and were down‐regulated in tumour samples. Moreover, we demonstrated that the EOMES directly bound at the transcriptional regulatory regions of the key inhibitory factors including PD‐1, CTAL‐4 and CD39, and lower levels of EOMES contributed to overexpression of these factors in T cells. Together, our studies provide new insight into the transcriptional deregulation of the inhibitory receptors on T cells during the tumorigenesis.
