The moderating effect of personal features on the consequences of an enjoyable co-creation experience
Authors: Füller Johann , Bilgram Volker 
Published: June 2017

Purpose
This study aims to draw a more nuanced picture of the impact of co-creation experience shedding light on the moderating role of consumers’ personal features. Virtual co-creation is considered a viable strategy to develop consumer-centered products in the digital era. As an additional effect, this research highlighted that co-creation experiences may establish beneficial consumer–brand relationships.

Design/methodology/approach
Using survey data stemming from 727 consumers who virtually engaged in new product development projects, the authors test the hypotheses, applying structural equation modeling.

Findings
The results of this study show that consumers’ personal features such as novelty seeking and dissatisfaction with existing products moderate the impact of an enjoyable experience on aspects of the consumer–company relationship. Consumers’ dissatisfaction with current product solutions is also found to moderate the relationship between an enjoyable co-creation experience and evoked product interest as well as between product involvement and evoked product interest. The study further substantiates previous findings on the relationship-effects of co-creation and particularly highlight the potential of co-creation experiences for nurturing “imaginary” relationships with the product being co-created significantly prior to market launch.

Originality/value
Participants in virtual co-creation approaches are widely heterogeneous individuals ranging from customers and Facebook fans to brand community members and innovative users. The study contributes to a better understanding of how the diversity of the crowd can be handled in virtual co-creation and advances the theory of value co-creation as a new marketing paradigm.
Self-presentation, privacy and electronic word-of-mouth in social media
Authors: Pasternak Oleksandra , Veloutsou Cleopatra , Morgan-Thomas Anna 
Published: June 2017

PurposeThis study aims to explore the nature of electronic word-of-mouth (eWOM) and the key drivers of this consumer-generated brand communication, focusing on eWOM in the context of social media communications.Design/methodology/approachThe study uses inductive qualitative design, and the data have been collected via 22 semi-structured interviews with individuals who follow brands on Facebook.FindingsBuilding on interview data, the paper advances a conception of eWOM in the social media context and highlights that eWOM consists of a broad range of brand-related communications, which include such activities as consuming, commenting, posting and forwarding information. The study also uncovers two major antecedents of eWOM, which are one’s concern for self-presentation and privacy.Research limitations/implicationsFurther research could examine additional drivers of brand-related eWOM in the context of Facebook brand pages, and investigate eWOM in other social media platforms.Practical implicationsThe findings have two important implications for brand management. Firstly, considering the importance of self-presentation, brands are advised to develop an in-depth understanding of the types of self-image pursued by their target audience. Secondly, given the concerns about privacy on social media, brands may carefully consider and manage the levels of privacy that should apply when communicating with their followers.Originality/valueThe novel insights centre on the individual differences in eWOM activity, and the importance of one’s perceptions of self-image and privacy in explaining these differences. It seems that the propensity to engage in eWOM and the form that this communication takes are the reflections of one’s self-presentation and privacy preferences.
Is it about task conflict or relationship conflict?

Published: June 2017

PurposeBased on the team conflict theory and organizational learning theory, this study aims to discuss the two different types of conflicts of the top management team (TMT) on the different mechanisms of exploratory learning behavior of firms, and, based on the perspective of CEO-TMT (CEO – chief executive officer) interface, the different moderating effects caused by different CEO leadership styles are clarified.Design/methodology/approachUsing the sample of 193 firms’ samples with multi-source data, the authors take an empirical test of the theoretical framework.FindingsThe effect of task conflict on exploratory learning behavior was insignificant, and relationship conflict had a positive effect on exploratory learning behavior. However, when CEO’s transformational leadership level was high, or transactional leadership level was low, there existed “bathtub curve” relationship between task conflict and exploratory learning behavior, and the relationship conflict under these conditions strengthened exploratory learning behavior. When CEO’s transactional leadership level was high, or transformational leadership level was low, there existed the inverted U-shaped relationship between task conflict and exploratory learning behavior, and the relationship conflict under such conditions weakened exploratory learning behavior.Originality/valueFirst, the authors challenge the assumption of linear mechanism of task conflict, trying to build the mechanism of curve hypothesis, and the nonlinear explanation might be able to integrate the inconsistent results in the existing literature. Second, according to the inconsistent results of relationship conflict in existing literature, this study takes perspective of the CEO-TMT and introduces CEO leadership behavior as a moderating variable to test the moderating effect of CEO leadership and clarifies the boundary conditions of TMT conflicts.
Constructing a process model for low-carbon supply chain cooperation practices based on the DEMATEL and the NK model
Authors: Bai Chunguang , Sarkis Joseph , Dou Yijie 
Published: June 2017

PurposeThis paper aims to introduce a joint DEMATEL and NK methodology to develop a process model for introducing and implementing relational supply chain practices for low-carbon supply chains. Using this process model as a guide, insights into specific practices and how to implement these relational practices to achieve competitive advantage across organizations are introduced.Design/methodology/approachLow-carbon cooperation practices framework based on the relational view is developed. A methodology based on DEMATEL and the NK model is used to construct a sequential process model for introducing and implementing these relational practices. Empirical data from three manufacturing organizations in China are utilized to validate the model.FindingsInitial results provide a sequence of relational practices for guiding those organizations and their suppliers for healthy and low-carbon development. Interdependencies between relational practices are analyzed and evaluated from four aspects. Insights into the broader application of the methodology and initial results from both a research and managerial perspective are presented, especially with consideration of the China, an emerging economy, context.Research limitations/implicationsThe methodology remains relatively abstract in nature, yet the tool can provide very useful interpretations and information for both researchers and practitioners.Practical implicationsThis paper stipulates that in addition to internal operational practices, the relational practices between buyer and supplier may be equally important to achieve a low-carbon outcome, especially in supply chain setting. This paper also shows that not only the relational practice itself but also the implementation sequence of the relational practices can relate to performance. According to the authors’ initial results, organizations in this study should first develop product development cooperation, then exchange carbon knowledge and implement effective governance and last build a trust relationship with its suppliers for low-carbon cooperation.Originality/valueThis is one of the few approaches that directly evaluates and identifies the interdependencies among relational practices and to construct a process model for introducing and implementing low-carbon supply chain cooperation. It is also the first time that the NK model has been integrated with DEMATEL. Focusing on Chinese supply chain carbon emissions concerns is also a unique perspective.

Authors: Avery Gayle , Hooper Narelle 
Published: June 2017

Purpose
This interview demonstrates how CEOs can focus on CSR to engage the workforce and change the culture and performance of an organization.

Design/methodology/approach
This article reports on an interview with Dr David Cooke, Managing Director of Konica Minolta Australia.

Findings
By introducing CSR to the firm, and in particular pursuing the UN’s Sustainable Development Goal (SDG) #8 against human trafficking, the MD not only changed the management style and culture in the organization, but also enhanced commercial results. Performance improved across many measures: revenue, profit, market share in a declining marketplace, highest number of units placed into the Australian market, increasing prestige associated with the company’s brand, and becoming an employer of choice.

Research limitations/implications
The findings are consistent with the literature on corporate sustainable investment, but further studies are needed to fully understand the processes involved in changing culture and improving performance via CSR.

Practical implications
This interview clearly shows the steps that the new CEO took in radically changing the culture of his organization by adopting CSR extensively.

Social implications
The power of business is vital to pursuing societal goals, and the case of Konica Minolta Australia demonstrates that doing so also benefits the company.

Originality/value
This study clearly explains how a corporate culture was changed and performance enhanced through a strategy based on investment in social issues.
Urine is an important nitrogen source for plants irrespective of vegetation composition in an Arctic tundra: Insights from a 15N‐enriched urea tracer experiment

Published: June 2017

Abstract

Mammalian herbivores can strongly influence nitrogen (N) cycling and herbivore urine could be a central component of the N cycle in grazed ecosystems. Despite its potential role for ecosystem productivity and functioning, the fate of N derived from urine has rarely been investigated in grazed ecosystems.

This study explored the fate of 15N‐enriched urea in tundra sites that have been either lightly or intensively grazed by reindeer for more than 50 years. We followed the fate of the 15N applied to the plant canopy, at 2 weeks and 1 year after tracer addition, in the different ecosystem N pools.

15N‐urea was rapidly incorporated in cryptogams and in above‐ground parts of vascular plants, while the soil microbial pool and plant roots sequestered only a marginal proportion. Furthermore, the litter layer constituted a large sink for the 15N‐urea, at least in the short term, indicating a high biological activity in the litter layer and high immobilization in the first phases of organic matter decomposition.

Mosses and lichens still constituted the largest sink for the 15N‐urea 1 year after tracer addition at both levels of grazing intensity demonstrating their large ability to capture and retain N from urine. Despite large fundamental differences in their traits, deciduous and evergreen shrubs were just as efficient as graminoids in taking up the 15N‐urea. The total recovery of 15N‐urea was lower in the intensively grazed sites, suggesting that reindeer reduce ecosystem N retention.

Synthesis. The rapid incorporation of the applied 15N‐urea indicates that arctic plants can take advantage of a pulse of incoming N from urine. In addition, δ15N values of all taxa in the heavily grazed sites converged towards the δ15N values for urine, bringing further evidence that urine is an important N source for plants in grazed tundra ecosystems.

Published: June 2017

SummarySome biomarkers play important roles in the endothelial dysfunction of patients with pulmonary arterial hypertension (PAH), including nitric oxide (NO), endothelin‐1 (ET‐1), asymmetric dimethylarginine (ADMA), galectin‐3 (Gal‐3), B‐type natriuretic peptide (BNP), and uric acid (UA). However, studies on these biomarkers in pulmonary artery blood in congenital heart disease‐PAH (CHD‐PAH) and the effect of iloprost on the regulation of biomarkers are lacking. This study investigated potential CHD‐PAH biomarkers and their association with the severity of disease. The effect of iloprost on the regulation of these biomarkers was also studied. A total of 31 patients with CHD‐PAH were enrolled. Seven with positive effects of iloprost (the average reduction in mPAP 11.13±1.73 mm Hg) and 19 with negative effects of iloprost (the average reduction in mPAP 4.21±4.87 mm Hg; iloprost positive group [IPG] vs iloprost negative group [ING], P<.01) and five age‐matched controls were studied. The pulmonary artery blood sample was collected before and after inhaling iloprost, and the plasma concentrations of Gal‐3, ADMA, ET‐1, and NO were measured. A significant positive linear relationship was observed between mPAP and plasma ET‐1, BNP, ADMA, and UA levels in all patients with CHD‐PAH. ET‐1, ADMA, BNP, and UA levels had a significant linear relationship with mean pulmonary arterial pressure, which could be used to predict the severity of CHD‐PAH. ET‐1 might be a potential biomarker to pre‐evaluate the effect of iloprost on CHD‐PAH. Iloprost could affect the expression of Gal‐3 and, therefore, the process of fibrosis could be influenced by iloprost.
Hypoxia/IL‐1α axis promotes gastric cancer progression and drug resistance
Authors: Xuan Yi , Wang Ya Nong 
Published: June 2017

OBJECTIVEThe microenvironment of tumors constitutes a unique niche that promotes cancer metastasis and resistance. Two remarkable characteristics of this microenvironment are hypoxia and inflammation. Interleukin‐1α (IL‐1α), an important inflammatory factor, is frequently upregulated in a variety of cancers. This study aimed to investigate the expression of IL‐1α in gastric cancer (GC) and explore the relationship between IL‐1α and hypoxia.METHODSReverse‐transcription polymerase chain reaction was performed to characterize IL‐1α expression in different GC cell lines under normoxia or hypoxia. IL‐1α expression was characterized in relation to tumor stage and lymph node metastasis of GC and the survival of patients. The effect of IL‐1α knockdown under normoxia or hypoxia on cell proliferation, migration and sensitivity to cisplatin was also evaluated. Additionally, hypoxia‐inducible factor‐1α (HIF‐1α) expression in KATO‐III cells was either upregulated by ectopic HIF‐1α expression or downregulated through shHIF‐1α transfection, the effects of which on IL‐1α expression was subsequently evaluated.RESULTS
There was a positive correlation between IL‐1α, which was upregulated during hypoxia, and tumor stage, lymph node metastasis and resistance to cisplatin in GC. IL‐1α was regulated by HIF1α, and a change in HIF1α expression altered the tumor‐promoting effect of IL‐1α.CONCLUSIONThe IL‐1α/hypoxia axis may be a valuable target for diagnosis and treatment of GC.

Published: June 2017

AbstractIntroductionAcute radiation oesophagitis (ARO) is frequently experienced by patients receiving concurrent chemo‐radiation therapy (cCRT) for non‐small‐cell lung cancer (NSCLC). We investigated ARO symptoms (CTCAE v3.0), radiation dose and oesophageal FDG PET/CT uptake.MethodCandidates received cCRT (60 Gy, 2 Gy/fx) and sequential FDG PET/CT (baseline FDG0, FDGwk2 and FDGwk4). Mean and maximum standardized uptake value (SUVmean and SUVmax) and radiation dose (Omean and Omax) were calculated within the whole oesophagus and seven sub‐regions (5–60 Gy).ResultsForty‐four patients underwent FDG0 and FDGwk2, and 41 (93%) received FDGwk4, resulting in 129 PET/CT scans for analysis. Of 29 (66%) patients with ≥ grade 2 ARO, SUVmax (mean ± SD) increased from FDG0 to FDGwk4 (3.06 ± 0.69 to 3.83 ± 1.27, P = 0.0019) and FDGwk2 to FDGwk4 (3.10 ± 0.75 to 3.83 ± 1.27, P = 0.0046). Radiation dose (mean ± SD) was higher in grade ≥2 patients; Omean (47.5 ± 20 vs 53.9 ± 10.2, P = 0.0061), Omax (13.7 ± 9.6 vs 20.1 ± 10.6, P = 0.0009) and V40 Gy (8.0 ± 8.2 vs 11.9 ± 7.3, P = 0.0185).ConclusionsFDGwk4 SUVmax and radiation dose were associated with ≥ grade 2 ARO. Compared to subjective assessments, future interim FDG PET/CT acquired for disease response assessment may also be utilized to objectively characterize ARO severity and image‐guided oesophageal dose constraints.
Sevoflurane vs. propofol in post‐operative catheter‐related bladder discomfort: a prospective randomized study
Authors: Kim H.‐C. , Park H.‐P. , Lee J. , Jeong M.‐H. , Lee K.‐H. 
Published: June 2017

BackgroundPost‐operative catheter‐related bladder discomfort (CRBD) causes increased emergence agitation. Muscarinic receptor activation is a major mechanism in CRBD development. Experimental studies showed that sevoflurane has anti‐muscarinic effects whereas propofol does not. Our hypothesis was that sevoflurane anaesthesia would reduce the incidence of CRBD following bladder surgery.MethodsIn total, 82 patients undergoing transurethral bladder tumour excision (TURBT) were assigned randomly to two groups according to the maintenance anaesthetic agent received: sevoflurane (n = 41) or propofol (n = 41). The incidence of CRBD was evaluated at 0, 1, 6 and 24 h post‐operatively. The number of patients treated with a rescue medication (tramadol) for CRBD was noted.ResultsThe incidence of CRBD at post‐operative 1 h was lower in the sevoflurane group than that in the propofol group (59% vs. 85%; P = 0.007). The differences in CRBD were 27% and 22% at 0 and 6 h post‐operatively (P = 0.008 and 0.047, respectively). CRBD occurred in 27 (66%) patients in the sevoflurane group vs. 38 (93%) in the propofol group from 0 to 24 h post‐operatively (P = 0.005). The number of patients treated with tramadol was lower in the sevoflurane group (13 [22%] vs. 22 [54%]; P = 0.044).ConclusionSevoflurane, as a maintenance in general anaesthesia, decreased the incidence of early post‐operative CRBD and tramadol requirements in patients undergoing TURBT, compared with propofol.

AbstractThere is no standardized method for assessing serum total mast cell tryptase (MCT) in anaphylaxis. The consensus equation (peak MCT should be>1.2× baseline tryptase+2 mg/L) has been proposed to interpret acute MCT in mast cell activation syndrome (MCAS). To validate consensus equation in a perioperative setting analyses of cases of suspected perioperative anaphylaxis during general anaesthesia (GA) were performed. Anaphylaxis was defined as per World Allergy Organisation (WAO) criteria. Timed serial MCT measurements were mapped against the consensus equation and receiver operating characteristic (ROC) curves produced. A total of 82 patients (60 females, mean age 56.5 years±SD17.2) underwent investigation. Sixty (73%) patients fulfilled WAO criteria for anaphylaxis, and 22 patients did not. Aetiology included 59% IgE‐mediated anaphylaxis, 2% non‐IgE‐mediated anaphylaxis, 12% anaphylaxis of unknown cause and 27% deemed non‐anaphylaxis. IgE‐mediated anaphylaxis included the following: NMBA (35%), antibiotics (46%), chlorhexidine (8%), patent blue dye (8%) and others (8%). An acute MCT with a comparable baseline was available in 71 of 82 (87%) patients (60 anaphylaxis and 11 controls). The median interquartile range (IQR) time from reaction to peak MCT was 1.34 (0.82‐2.51) hours. Analyses confirmed that a rise in acute MCT greater than that defined by the equation had a sensitivity, specificity, positive predictive value (PPV) and negative (N) PV of 78%, 91%, 98% and 44%, respectively. The magnitude of increase in acute MCT above the threshold predicted by consensus equation was higher in the anaphylaxis group compared to controls (P=.0001). This equation has a high specificity, PPV with a moderate NPV and sensitivity in perioperative anaphylaxis.
Systematic differences between ultrasound and pathological evaluation of thyroid nodules: a method comparison study
Authors: Chew Carolyn R. , Lam Tracey , Chan Steven T. F. , Chin‐Lenn Laura 
Published: June 2017

BackgroundThe size of thyroid nodules as measured by ultrasound (ultrasound size, USS) is routinely used in clinical decision‐making. Reports of discrepancy between USS and pathological size (PS) evaluation have not analysed their systematic differences. The objective of this study was to uncover the lack of agreement (bias) between USS and PS measurements.MethodsA retrospective study was performed on 121 patients who had a total or hemi‐thyroidectomy for a solitary nodule. Ordinary least product regression was used to detect and distinguish constant and proportional bias in unidimensional size measurements between USS and PS evaluation. Three‐dimensional volume measurements were compared in a subgroup of 31 patients. Pre‐specified acceptable limits of interchange were defined as 20% difference.ResultsOrdinary least product regression demonstrated no constant or proportional bias between the two methods; regression equation: USS = (0.863) + (1.040) × PS. When nodules were grouped by size, discrepancies between the two methods were observed in nodules <10 mm (P = 0.004). However, potential overtreatment of patients with USS >10 mm but PS <10 mm only accounted for 4.1% of total patients. Subgroup analysis of volume measurements showed no bias between USS and PS evaluation.Conclusions
USS and PS measurements were interchangeable, as there was no evidence of constant or proportional bias between the two measurements. However, USS may misclassify the size for smaller nodules and potentially lead to unnecessary workup and treatment. Discrepancy in size measurements between USS and PS should be taken into account in clinical practice, particularly in smaller nodules.
