Outcomes of team creativity: a person-environment fit perspective
Authors: Bam Louzanne , De Stobbeleir Katleen , Vlok PJ 
Published: May 2019

PurposeLimited research where team creativity (TC) is positioned as an independent variable constitutes a weak point in the body of knowledge. This paper aims to offer three contributions to address this research gap: empirical research that has been conducted on the outcomes of TC is summarized; a person–environment fit perspective is applied to develop a conceptual model for TC; and directions for future empirical research are proposed.Design/methodology/approachA literature review is conducted to identify empirical research on the outcomes of TC. This is summarized into an extension of an existing framework that organizes empirical research on the antecedents of TC. Furthermore, the fit model for TC is developed, based on a person–environment fit perspective.FindingsResearch on the outcomes of TC has focused on three themes: performance; affective state; and processes. Gaps in this body of knowledge include limited knowledge on performance outcomes and a lack of research on potential negative outcomes. Recommendations for future research include: potential moderators of the relationship between TC and two outcome, innovation and team performance, are proposed; strain and unethical decision-making are proposed as potential negative outcomes of TC; and it is proposed that incorporating a temporal dimension would improve the understanding of the cyclical manner in which certain variables and TC may interact over time.Originality/valueThe organizing framework extension summarizes existing knowledge on the outcomes of TC, and together with the fit model for TC, this offers a basis for identifying research gaps and directions for future research. Specific directions for future empirical research are proposed.

AbstractThis study evaluated effects of green compared with brown coating colors and varying levels of hydrolyzed squid peptide powder (HSP) on seafood flavor perception, sensory liking, emotions, and purchase intent (PI) of coated peanuts. Dried squid head was enzymatically hydrolyzed to produce HSP, which was then incorporated into peanut coating material at 0%, 0.89%, 1.78%, and 2.66% levels. Green‐coated peanuts (GCP) and brown‐coated peanuts (BCP) were produced and tested with U.S. consumers. A 2‐AC test (N = 100 consumers) was used to determine effects of coating colors on expected/perceived seafood flavor intensity of GCP compared with BCP at an equal HSP level based separately on looking, smelling, and tasting. Only tasting produced perceptual differences, at 1.78% and 2.66% HSP, with stronger seafood flavor intensity observed for GCP. Consumer testing (N = 160) yielded low mean seafood aroma liking scores for BCP (4.04) and GCP (4.13) at 2.66% HSP. The emotion “disgusted” was most affected by HSP addition for GCP. Presenting consumers with health benefit information (HBI) increased positive PI from 62.5% to 81.25% for BCP at 1.78% HSP, which had higher mean overall liking scores (6.05 before HBI, 6.24 after HBI) than 2.66% HSP samples. Overall liking was a significant predictor for positive PI with odds ratios of 1.52 to 2.20. Overall, green color and HSP addition levels of the coating inserted negative effects on liking, emotion, and PI of coated peanuts. This study demonstrated that HSP made from byproduct of squid processing could be successfully incorporated into coated peanuts, supporting the concept of sustainability of food supply.Practical ApplicationIn this study, the functional peptide ingredient made from squid head, a byproduct from seafood industry, was incorporated into coated peanuts. Effects of different coating colors (green compared with brown) and varying levels of hydrolyzed squid peptide powder on consumers’ seafood flavor perception, liking, emotions, and purchase intent of seasoned coated peanuts were clearly observed. The color of the coating material played an important visual cue that influenced product liking. Presenting consumers with health benefit information increased overall liking and positive purchase intent of the samples. Multisensory interactions of color and seafood aroma/flavor in these products should be further optimized.

AbstractThe preservation effects of tartary buckwheat extract (T) and chitosan (C) coatings on the physicochemical (pH value, thiobarbituric acid value, Peroxide value (PV), total volatile basic nitrogen (TVB‐N), K value, surface color and the texture profiles), bacteriological (total viable counts (TVC) and psychrotrophic bacteria counts (PBC)), and sensory characteristics of tilapia (Oreochromis niloticus) fillets storage at 0 °C for 18 days were evaluated. The fillets coated with 0.5% T + 1.0% C, 1.0% T + 1.0% C and 1.5% T + 1.0% C maintained better quality and had longer shelf life with respect to samples coated with chitosan alone and the control. Base on the limit values of TVB‐N, K value, TVC and sensory preference scores, the shelf life of control fillets was 6 days. By contrast, shelf life of 9 days for 0.5% T + 1.0% C‐coated fillets, 12 days for 1.0% T + 1.0% C treated‐fillets, and 15 days for 1.5% T + 1.0% C‐treated fillets were obtained. Therefore, TBE combined with chitosan coatings have the potential to extend the shelf life of tilapia fillets during storage at 0 °C.Practical ApplicationThis study provides basic theory regarding the application of TBE to fish preservation. The edible coating of TBE combined with chitosan has potential use in developing activity food preservation coating.

Published: May 2019

BackgroundNo effective treatment is currently available for poorly differentiated thyroid cancer which is resistant to radioiodine, especially with migration and invasion. A great number of researches have revealed the anticancer effects of salidroside, but none have studied the effects of salidroside on thyroid cancer. This study aimed to investigate the effect of salidroside on migration and invasion of poorly differentiated thyroid cancer cells.MethodsThe effects of salidroside on migration, invasion and apoptosis of poorly differentiated thyroid cancer WRO cells and normal thyroid follicular epithelial Nthy‐ori 3‐1 cells were measured by wound‐healing assay, transwell migration/invasion assay and flow cytometry, respectively. The expression levels of MMP2 and MMP9 at RNA and protein levels in WRO cells were detected by qRT‐PCR and western blot. The phosphorylation levels of Janus kinase 2 (JAK2), signal transducer and activator of transcription 3 (STAT3) and the apoptosis‐related protein levels of Bax, cleaved caspase 3 and Bcl‐2 were assessed by western blot.ResultsSalidroside significantly suppressed migration/invasion and induced apoptosis in poorly differentiated thyroid cancer WRO cells. We further illustrated that salidroside significantly inhibited expressions of MMP2 and MMP9 at mRNA and protein levels and the phosphorylation activation of JAK2/STAT3 in WRO cells. In addition, salidroside increased expressions of pro‐apoptotic factors (Bax and cleaved caspase 3) and decreased expression of anti‐apoptotic factor (Bcl‐2) significantly in WRO cells.ConclusionThe present study demonstrates that salidroside inhibits migration and invasion of WRO cells (a kind of poorly differentiated cancer cell line) significantly, which might be via suppressing JAK2‐STAT3 signaling pathway.

AbstractThe health of oviduct circulation is very important for normal egg production. The present work describes the histology and histochemistry of vessels of different types on the oviduct of quail. Arteria, venae and lymphatics of the oviduct were described clearly. In addition, special vascular elements were observed presenting circular, longitudinal and oblique smooth muscle fibres on the blood vessel wall. Glomus cells were observed at typical glomus vessels, atypical glomus vessels and on the wall of some of arteria and arteriolae. Also, spirally oriented blood vessels were observed. Dark brown pigment was detected in the wall of arteria, venae, lymphatics and the special types of blood vessels.

AbstractAimTo assess the prognostic significance of enhancement rate (ER) measured by contrast‐enhanced ultrasonography (CEUS) in patients with hepatocellular carcinoma (HCC) undergoing radiofrequency ablation (RFA).Materials and methodsA total of 253 patients with single primary HCC undergoing preoperative CEUS and RFA were enrolled in this study. The ER were evaluated though pretreatment CEUS. After a mean follow‐up of 36.8 ± 10.2 months, the correlation of ER measured by CEUS and survival after RFA was analyzed by univariate and multivariate analysis. The optimal cutoff ER value to predict survival was determined using receiver‐operating characteristic analysis.ResultsMean follow‐up period for all 253 patients was 36.8 ± 10.2 months, 31.2% of patients had died at endpoint. The optimal cutoff ER value predicting survival was 2.2 dB/s. Univariate analysis demonstrated that patients with a high ER level had poorer OS (62.8 months vs 48.8 months, P = 0.02) and recurrence‐free survival (RFS = 60.2 months vs 47.4 months, P = 0.03) than patients with a low ER level. ER measured by CEUS also been confirmed as independent risk factor for overall survival (hazard ratio [HR], 1.87; 95% confidence interval [95% CI], 1.21–7.25; P < 0.01) and RFS (HR, 1.67; 95% CI, 1.08–6.21; P < 0.01) in multivariate analysis enrolling gender, BMI, tumor size, antiviral therapy, HBV DNA, histological differentiation, Child–Pugh score and tumor node metastasis (TNM) stage.ConclusionsER measured by CEUS was a significant predictive factor for survival after RFA for HCC.
Intolerance of uncertainty and anxiety as explanatory frameworks for extreme demand avoidance in children and adolescents
Authors: Stuart Lisa , Grahame Victoria , Honey Emma , Freeston Mark 
Published: May 2019

BackgroundPathological demand avoidance (PDA) is a proposed subtype of autism spectrum disorder (ASD), characterised by extreme avoidance of demands. Demand avoidant behaviour has been proposed to be driven by an anxious need to be in control, although has never been explicitly studied. Emerging evidence suggests intolerance of uncertainty (IU) and anxiety may explain the behaviours seen in ASD. We propose these concepts may be useful starting points for furthering understanding of PDA.MethodsIn Study 1, quantitative methods examined the relationship between PDA, IU and anxiety using data collected in an online survey (N = 214). The sample included cases with clinically diagnosed PDA (n = 69) and those with no clinical diagnosis but parent‐identified features of PDA (n = 151). ‘Children with a diagnosis of PDA scored significantly higher on the IUS‐P (t(212) = 2.45, p < .05) compared to those without a diagnosis of PDA. PDA diagnosis did not impact on scores on any other measure.’ In Study 2, a selection of Study 1 participants (n = 11) were followed up with a telephone interview to gain descriptive data relating to PDA and its association with IU and anxiety.ResultsRegression analyses indicate that demand avoidant behaviour can be conceptualised in part as a possible attempt to increase certainty and predictability to alleviate increasing anxiety. Children and young people with PDA employed varying strategies to manage IU depending on the level of demand presented and degree of anxiety generated. These strategies can be represented by different features of the behaviour profile seen in PDA (control behaviour, withdrawal to fantasy, and meltdown). These behavioural features of PDA showed differential relationships with IU and anxiety, although all were predicted by IU, only meltdown demonstrated a mediation effect by anxiety.ConclusionsThis study represents one of the first attempts to conceptualise and understand the behavioural features of the PDA profile in children and young people. It builds upon emerging evidence from the ASD literature that IU is a relevant construct for conceptualising demand avoidant behaviour in children who show PDA behaviour. This has potential clinical implications for the assessment and management of PDA in children and young people.

Background and AimClinical significance of endoscopic response (ER) after neoadjuvant chemotherapy (NAC) for esophageal cancer has not been fully understood. Thus, the present study aimed to investigate the association between ER to NAC and its clinicopathological outcomes in patients with esophageal squamous cell carcinoma (ESCC).MethodsIn total, 141 patients who underwent NAC and subsequent esophagectomy for ESCC were included. ER to NAC was retrospectively evaluated based on macroscopic findings of the primary tumor, which was classified into three categories: endoscopic no response (eNR), endoscopic partial response (ePR), and endoscopic good response (eGR). An endoscopic responder was defined as patients with eGR/ePR.ResultsApproximately 89.4% of patients had cStage II–III disease, and 7.1% had pathological complete response. Upon ER evaluation, eNR, ePR, and eGR were observed in 46 (32.6%), 54 (38.3%), and 41 (29.1%) patients, respectively. Pathological responders significantly increased as the ER grade became better. Among preoperative clinical factors, only ER significantly correlated with pathological response in univariate and multivariate analysis. Endoscopic responders showed a significantly better prognosis than did eNR patients (P < 0.001), although the overall survival (OS) of the patients with eGR and ePR was equivalent. Endoscopic responder, ypT, ypN, and pathological responder were significant predictors of OS in the univariate analysis, and endoscopic responder, ypN, and pathological responder were independent predictors in the multivariate analysis.ConclusionThis study suggests that ER can be a simple and important tool to predict the pathological response and survival of patients who undergo NAC for ESCC.
Reliance on lakes by salmon, trout and charr (Oncorhynchus,SalmoandSalvelinus): An evaluation of spawning habitats, rearing strategies and trophic polymorphisms
Authors: Arostegui Martin C. , Quinn Thomas P. 
Published: May 2019

AbstractSalmonid fishes may reside within or migrate between stream and lake habitats, or undergo anadromous migrations between freshwater and the ocean. While the degree of anadromy of salmonids has been thoroughly compared, no analogous review has examined the degree of lake use. To assess the extent of reliance on lake habitat in this family, we considered 16 species of salmon, trout and charr from the generaOncorhynchus,SalmoandSalvelinus,comparing their (a) use of lakes as spawning habitat, (b) rearing strategies in lakes, and (c) occurrence and diversity of lacustrine trophic polymorphism. In identifying the primary life‐history patterns of each species and exploring the lesser‐known lacustrine behaviours, we found that the extent of reliance on lakes exhibits a negative association with the degree of anadromy.Oncorhynchusrely least on lakes,Salmoto an intermediate level andSalvelinusthe most, opposite of the general prevalence of anadromy among these genera. Lakes are critical to adfluvial and lake‐resident salmonids, but they also support anadromous and fluvial life histories by providing spawning, rearing, overwintering and/or summer refuge habitat. Adfluviality, although a non‐anadromous life history, consists of similar migration‐related traits and behaviours as anadromy, including the parr–smolt transformation, sex‐biased patterns of migration and residency, and the presence of precocious males. Lakes support life‐history variants, reproductive ecotypes and trophic morphs unique to lacustrine habitat. Therefore, conservation of salmonids is dependent on maintaining the diversity and quality of their habitats, including lakes.
Phosphorylation of Arabidopsis eIF4E and eIFiso4E by SnRK1 inhibits translation

Published: May 2019

Regulation of protein synthesis is critical for maintaining cellular homeostasis. In mammalian systems, translational regulatory networks have been elucidated in considerable detail. In plants, however, regulation occurs through different mechanisms that remain largely elusive. In this study, we present evidence that the Arabidopsis thaliana energy sensing kinase SnRK1, a homologue of mammalian AMP‐activated kinase and yeast sucrose non‐fermenting 1 (SNF1), inhibits translation by phosphorylating the cap binding proteins eIF4E and eIFiso4E. We establish that eIF4E and eIFiso4E contain two deeply conserved SnRK1 consensus target sites and that both interact with SnRK1 in vivo. We then demonstrate that SnRK1 phosphorylation inhibits the ability of Arabidopsis eIF4E and eIFiso4E to complement a yeast strain lacking endogenous eIF4E, and that inhibition correlates with repression of polysome formation. Finally, we show that SnRK1 over‐expression in Nicotiana benthamiana plants reduces polysome formation, and that this effect can be counteracted by transient expression of eIF4E or mutant eIF4E containing non‐phosphorylatable SnRK1 target residues, but not by a phosphomimic eIF4E. Together, these studies elucidate a novel and direct pathway for translational control in plant cells. In light of previous findings that SnRK1 conditions an innate antiviral defense and is inhibited by geminivirus pathogenicity factors, we speculate that phosphorylation of cap binding proteins may be a component of the resistance mechanism.
The syndicate structure of securitized corporate loans
Authors: Guo Zhengfeng , Zhang Shage 
Published: May 2019

AbstractSecuritized loans have lower lead bank shares, but larger shares held by non‐CLO (collateralized loan obligation) institutional investors than nonsecuritized loans. The result can largely be explained by their degree of information asymmetry and credit risk. We find that lead banks increase their holdings after a nonsecuritized loan becomes securitized, but they do not reduce financial exposure to securitized facilities during the boom of the CLO market. Furthermore, we find that securitized loans do not perform differently from similar nonsecuritized loans. We conclude that differences in syndicate structure are likely shaped by participants’ investment preference rather than a manifestation of adverse selection.
Development of circulating CD4+ T‐cell memory

Published: May 2019

AbstractThe ability of circulating CD4+ T cells to retain memories of previous antigenic encounters is a cardinal feature of the adaptive immune system. Over the past two decades, since the first description of central and effector memory T cells, many studies have examined molecular mechanisms controlling CD8+ T‐cell memory, with comparatively less research into CD4+ T‐cell memory. Here, we review a number of seminal studies showing that circulating memory CD4+ T cells develop directly from effector cells; and in so doing, preserve features of their effector precursors. We examine mechanisms controlling the development and phenotypes of memory CD4+ T cells, and provide an updated model that accommodates both the central and effector memory paradigm and the diverse T helper cell classification system.
(New) Bulgarian Enlighteners and Ambassadors? The Reinvention of National Identity in Times of Crisis
Authors: Genova Elena 
Published: May 2019

AbstractDrawing on empirical data from 37 Bulgarian students and young professionals in the UK, this article explores the intersection of the discourses produced by the European crises and migrants' national identity. In Bulgaria, the crisis narrative is embedded in the arguably never‐ending democratic transition, manifested in socio‐economic instability and political volatility. Simultaneously, “Brexit Britain” is enveloped in strong Eurosceptic sentiments, propelled by a combination of austerity measures and intensified Eastern European migratory flows. Both contexts subject Bulgarian migrants to stigmatizing representations. Looking at migrants' everyday practices, the data reveals that young Bulgarians draw on the related ideas of the “new” Enlightener and Ambassador to counterbalance negative discourses. Thus, the article explores the meanings and significance attributed to the Enlighteners and the Ambassadors, arguing that the participants engage in “social creativity” and “individual mobility” strategies that lead to reinvention of national identity.
