Purpose The purpose of this paper is to investigate and examine the factors contributing to consumers’ mobile shopping continuance intention (CI) of food and non-food items via smartphones and other mobile terminals. Design/methodology/approach An integrated model was proposed on the basis of the technology acceptance model (TAM) and expectation confirmation model (ECM), focussing on perceived value (PV). The survey responses of 203 Chinese mobile shoppers (m-shoppers) were analysed using structural equation modelling with the partial least squares approach. Findings The results indicated that perceived usefulness does not motivate all user groups. Furthermore, satisfaction and perceived ease of use significantly impacted different user groups. For online food m-shoppers, value for money (VM) was the most important factor influencing satisfaction and CI. However, perceived usefulness only affected CI for non-food m-shoppers. Practical implications Marketers can improve users’ CI by enhancing VM and maximising effectiveness and enjoyment while minimising prices. Moreover, in determining strategies for different users, marketers should identify the behavioural differences among all groups and those between the two classified groups. Originality/value This is one of the studies attempting to explain Chinese mobile shopping consumers’ CI, but especially through an integrated model based on TAM and ECM with PV on food and non-food m-commerce perspective. It offers several implications for researchers and practitioners and contributes to the literature of technology acceptance and post-adoption behaviour in m-commerce.
In response to the asking and requiring of stakeholders to be more environmentally responsible, firms must commit to green corporate social responsibility (CSR). Firms being green and responsible always can acquire intangible resources that are important for firm innovation. Given the scarcity of existing research addressing relevant issues in depth, this paper expands our understanding of green CSR by revealing its antecedent effects on firm innovation performance. We also include public visibility and firm transparency as contingency factors to explore the relationship between green CSR and firm innovation performance. Using data collected from publicly listed firms in China, we find that greater innovation performance is associated with an increase in firm green CSR, and the positive relationship between green CSR and innovation performance is moderated by public visibility and firm transparency. Based on the results, theoretical contributions and practical implications are outlined.
Based on stakeholder theory, this research aims to examine the effects of the two dimensions of corporate environmental responsibility (CER), which are CER strength and CER concern, on firm innovation performance, and the moderating effect of firm visibility on these relationships. Using data on Chinese firms listed on Shenzhen stock exchange from 2006 to 2015, this research finds that CER strength positively affects firm innovation performance while CER concern negatively affects innovation performance. These relationships are stronger for firms with greater visibility. This research provides insights for understanding the relationship between CER and innovation performance and has important managerial implications for firms to manage their environmental behaviors and improve innovation performance to achieve sustainable development.

Summary Pomegranate peel powders were prepared by superfine grinding, whose effects were investigated on the composition, functional and antioxidant properties of the pomegranate peel products. Fluidised bed jet milling technology was used to process superfine pomegranate peel powder. The physical–chemical properties of coarse powder A (D50 = 413.4 μm) and B (D50 = 197.1 μm), fine powder C (D50 = 142.6 μm) and D (D50 = 41.2 μm), superfine powder E (D50 = 7.68 μm) and raw material powder (RMP) (D50 = 352.2 μm) were investigated in this study. SEM images revealed the shape and surface morphology of six pomegranate peel powders. The physical determinations showed that the smaller the powder particle size was, the greater the surface area (from 0.214 to 1.597 m2 g−1) and bulk density (from 0.653 to 0.751 g mL−1) were, the smaller the angles of repose (from 51.69° to 38.74°) and slide (from 48.32° to 34.18°) were. The water holding capacity (WHC), water‐solubility index (WSI), polyphenols and flavonoids release were significantly improved as the size of pomegranate peel particle decreased. The results of FTIR and UV indicated that grinding process would not influence chemical composition of pomegranate peel. Vitamin C (VC) and butylated hydroxytoluene (BHT) were used in DPPH scavenging activity determination, and DPPH scavenging activity was A < RMP < BHT < B < C < D < E < VC.
PurposeThis study aims to offer and validate an integrated marketing capability-product innovations framework. Particularly, it aims to examine the role of adaptive marketing capability in enabling market ambidexterity and incremental as well as radical product innovation. Also it intends to investigate the moderating role of transformational leadership between adaptive marketing capability and market ambidexterity.Design/methodology/approachManufacturing firms in Pakistan, an emerging economy, are taken as the context for this study. A designed survey questionnaire is used for data collection. Partial least square technique is employed to empirically validate and test the hypothesized model with a sample of 192 manufacturing firms. Particularly, the two-stage approach in SmartPLS is used to validate measurement models, and structural equation modeling technique is used to test the proposed hypothesis.FindingsThe findings not only confirm that adaptive marketing capability is instrumental to both incremental and radical product innovations but also reveal that adaptive marketing capability serves an important antecedent to market ambidexterity shedding new lights on its mediating role in the relationship of adaptive marketing capability with incremental and radical product innovations. Moreover, the results find that the effectiveness of adaptive marketing capability to support market ambidexterity may involve a possible trade-off between exploitation and exploration when the leaders exhibit a low or high level of transformational leadership behavior.Originality/valueThis study contributes to outside-in strategic perspective and contextual ambidexterity literature by revealing the role of adaptive marketing capability as an important enabler of market ambidexterity which, in turn, allows the firm to simultaneously introduce incremental and radical product innovations. In this way, this study advances the current understanding of the antecedents and consequences of contextual ambidexterity. Also, this study provides insight into the types of capabilities needed for the firm's contextual and employees' behavioral adaptation to simultaneously manage exploitation and exploration within the same business unit which was lacking in the previous literature. Further, this study also offers a novel understanding of the conditional role of transformational leadership between adaptive marketing capability and market ambidexterity.
The prognostic biomarkers and potential therapy targets are urgently needed in hepatocellular carcinoma (HCC). In this article, we report the expression of TUBA1C was significantly increased in HCC on mRNA and protein level, and this finding was further validated in another two independent datasets. Survival analysis was also implemented on these three datasets, and TUBA1C high expression group was detected to have relative shorter survival time. Furthermore, the metastatic ability is increased along with TUBA1C abundance, according to protein abundance evaluation of normal-tumor-portal vein tumor thrombus pairs, and mRNA comparison between metastasis-averse HCC and metastasis-incline HCC. Correlation analysis was implemented and TUBA1C expression was shown to be significantly associated with recurrence, embolus, and AFP level. Proliferation and migration assays following knock down of TUBA1C in two cell lines, HCCLM3 and PLC, revealed that down-regulation of TUBA1C significantly reduces proliferation and migration in HCC cells. in vivo study also showed the similar results. Gene Set Enrichment Analysis (GSEA) comparing the TUBA1C-low and TUBA1C-high group indicates that KEGG pathways including “cell cycle”, “DNA replication”, and “proteasome” were significantly enriched in TUBA1C-high group. In conclusion, prognostic biomarker and oncogene TUBA1C promotes migration and proliferation of hepatocellular carcinoma cells, probability via cell cycle signaling pathway.
