Understanding mobile shopping consumers’ continuance intention
Authors: Shang Dawei , Wu Weiwei 
Published: January 2017

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.
Web-application development projects by online communities
Authors: Annarelli Alessandro , Battistella Cinzia , Nonino Fabio 
Published: January 2017

Purpose
The purpose of this paper is to propose an in-depth analysis of online communities of practice that support the innovative development of web applications. The analysis is aimed at understanding the preeminent characteristics of communities of practice that can favour the process of innovation (conceptualisation and realization of a web application) and if these characteristics differ in the diverse phases of a software development project (requirement specification, design, implementation and verification).

Design/methodology/approach
The authors adopted a multiple case study research design, selected 29 communities of practice related to the development of web applications and classified them recognizing the different practices that refer to the different phases of the innovation process of web-applications software development. Finally, the authors focussed on seven communities comparing five important dimensions for each one.

Findings
The results of the empirical analysis show that the best practices are different, considering the different phases of the project, and that these practices can be strategies directed at members to attract them and also, strategies directed at the community to permit collaboration.

Originality/value
The paper proposes an important and new insight into the management of virtual communities of practice (VCoP). The authors supposed that the ways to manage a VCoP could depend on project phases. In particular, the management practices of community should differ according to the different project phases, i.e. requirements specification, design, implementation and verification of the software. Literature in this sense presented only research focussed on the different effects of virtualness on teams depending on the length of team duration and on communication efforts.
Elastic and plastic innovation capability in firms
Authors: Zou Bo , Guo Feng , Song Michael 
Published: January 2017

PurposeAlthough the extant innovation literature has extensively explored the attributes of different types of innovation capability, little is known yet about the common phenomenon of the rebound and durableness of innovation capability. Therefore, the purpose of this paper is to address these aspects by introducing the concepts of elastic and plastic innovation capability.Design/methodology/approachBased on the behavioral theory of the firm, the authors propose a theoretical model to study the antecedents and outcomes of elastic and plastic innovation capability. An empirical testing involves two data sets that contained 183 companies in three industries. The empirical evidence supports the existence of the concepts of elastic and plastic innovation capability.FindingsThe research findings also demonstrate that a firm’s past performance is positively related to elastic innovation capability. Elastic innovation capability and organizational aspiration are positively related to plastic innovation capability. Both elastic and plastic innovation capability significantly lead to superior performance.Originality/valueThis study makes three main contributions to the existing innovation literature. First, the authors extend existing knowledge on innovation capability by proposing two new types of innovation capability – elastic and plastic innovation capability. Second, the proposed concepts of elastic and plastic innovation capability contribute to the theory of dynamic capability. Finally, this study reveals the micro-mechanism of elastic and plastic innovation capability from the perspective of the behavior theory of the firm and their different effect on firm performance.
Corporate governance and the level of Bahraini corporate compliance with IFRS disclosure
Authors: Juhmani Omar 
Published: January 2017

Purpose
The purpose of this paper is to examine the relation between corporate governance (CG) and International Financial Reporting Standards (IFRS) disclosure one year before the issuance of the first Corporate Governance Code (CGC) in Bahrain.

Design/methodology/approach
The CG is measured by board composition, audit committee characteristics, and ownership structure. Ordinary least-squares regressions are used to examine the relationships between the level of Bahraini corporate compliance with mandatory IFRS disclosure requirements as dependent variable and eight CG mechanisms as independent variables and five other firm-specific attributes, as control variables.

Findings
The results show that three of the CG mechanisms (i.e. board independence, audit committee independence, and Chief Executive Officer duality) are associated with the level of IFRS disclosure. This suggests that CG mechanisms are effective in the financial reporting practices. However, the results show that the other five CG mechanisms (i.e. board size, audit committee size, blockholder ownership, managerial ownership, and government ownership) are not associated with the level of IFRS disclosure. This result may prove the importance of the CGC as an effective enforcement mechanism to enforce Bahraini companies to fully comply with IFRS disclosure.

Research limitations/implications
Although the study can contribute to the understanding of the relationship between CG and IFRS in Bahrain, it may not be able to be generalized to other countries. Such relationships could be different from country to country due to business and legal environments. Therefore, there is a need to investigate these relationships among different countries. This study examines the relation between CG and the level of compliance with IFRS disclosure one year before the issuance of the first CGC in Bahrain. Future research might attempt to examine the relation one year after the issuance of the first CGC in Bahrain to confirm the importance of the CGCs as an effective enforcement mechanism.

Practical implications
The findings of this study are of great concern to all users of annual reports and of particular interest to accounting regulators to improve the level of supervision and the standard of reporting in Bahrain. Also, it is of great concern to professional accounting bodies, policy makers, and governments in emerging markets in countries that share similar economic, political, and cultural environments.

Originality/value
This paper’s contribution to the literature is twofold: it examines the relation between three groups of CG mechanisms (i.e. board characteristics, audit committee characteristics and ownership structure) and the level of corporate compliance with IFRS disclosure; it examines the relation one year before implementing the first CGC in Bahrain and provides new evidence on the importance and effectiveness of the CGCs.
Assessing the applicability of Hofstede’s cultural dimensions for Global 500 corporations’ Facebook profiles and content
Authors: Lo Kevin D. , Waters Richard D. , Christensen Nicklas 
Published: January 2017

PurposeThe purpose of this paper is to examine how Hofstede’s six cultural dimensions are reflected on the official corporate Facebook pages from 259 organizations onFortunemagazine’s Global 500 list. This is the first attempt to create a conceptualization of Hofstede’s dimensions for organizational social media use.Design/methodology/approachTo determine how Facebook is used by the Global 500 corporations, a content analysis was carried out based on the 2013 listing of the highest revenue corporations throughout the world. As a research method, content analysis allows researchers to examine the actual practices of communication by focusing on the information provided through textual and visual messages.FindingsThe results paint a mixed picture indicating that the global nature of these corporations is echoed in a somewhat similar overall presence on Facebook; but when the individual elements (About Us, updates, and media) are examined, statistical differences emerge in relation to the reflection of the cultural dimensions.Originality/valueTo the authors’ knowledge, this is the first work to match Facebook behaviors with Hofstede’s dimensions. This work needs to be replicated with other organizations to determine its staying power. In addition, future research might tap into agency and any consciousness on the part of social media managers in a specific direction. Depending on those findings, they might make important statements on the emergence of a global social media culture.
Renoprotective effect of Hypericum perforatum against diabetic nephropathy in rats: Insights in the underlying mechanisms
Authors: Abd El Motteleb Dalia M. , Abd El Aleem Dalia I. 
Published: January 2017

SummaryOxidative stress and inflammation play a key role in the initiation and progression of diabetic nephropathy (DN). The present study aimed to investigate the possible protective effect of hypericum perforatum (HP) against DN. Rats were allocated into six groups: control, received normal saline; diabetic untreated (DM), received single dose of streptozotocin (STZ) after injection of nicotinamide (NA); gliclazide, received STZ,NA + gliclazide (10 mg/kg); DM + HP50, DM + HP100, DM + HP200, received STZ,NA and HP 50, 100, 200 mg/kg, respectively. Gliclazide and HP were administered daily via gavage for 8 weeks. Serum glucose, insulin, kidney function and histopathological picture were assessed. Furthermore, oxidative/nitrosative stress, inflammatory cytokines, apoptotic and fibrotic markers were measured. Diabetic untreated group showed increase in serum glucose, urea, creatinine with albuminurea. Renal expression of protein for nuclear factor kappa‐B (NF‐кB), renal expression of inducible nitric oxide synthase (iNOS), cyclooxygenase II (COXII), collagen IV, fibronectin were elevated. Malondialdehyde (MDA), nitric oxide (NO), tumour necrosis factor‐α (TNF‐α), interleukin‐1β (IL‐1β), intracellular adhesion molecule (ICAM‐1), monocellular chemoattractant protein‐1 (MCP‐1), tumour growth factor‐ β (TGF‐β), caspase‐3 and cytochrome c contents were also increased consequently with decline of serum insulin, expression of peroxisome proliferator‐activated receptor (PPARγ), renal reduced glutathione (GSH) content and superoxide dismutase (SOD) activity. Treatment with either gliclazide or HP mitigated the deleterious effects of STZ on the tested parameters. These findings indicate for the first time that HP may have a renoprotective effect against DN through reduction of oxidative/nitrosative stress, enhancement of antioxidant defense mechanisms, decline of inflammatory cytokines, antifibrotic, antiapoptotic and blood glucose lowering properties.
Class, Politics and the Progressive Dilemma
Authors: Devine Fiona , Sensier Marianne 
Published: January 2017

AbstractThis article considers contemporary class inequalities and how they might shape a progressive politics in the UK. Drawing on findings from the BBC Class Survey, it outlines changes in the class structure, class mobility and class identities. It is argued that the class structure is increasingly polarised and fragmented, with a wealthy elite, a vulnerable precariat and fragmented middle and working classes in between. Declining upward social mobility is a source of anxiety for middle‐class and working‐class parents alike. Class identification, especially working‐class identification, has weakened over time, although class snobbery is far from dead. Class has changed and the class basis of politics is changing now too. A progressive politics is possible if the political parties of the centre‐left appeal to the majority of the electorate rather than one class, acknowledge common concerns and worries and appeal to shared hopes and dreams that straddle class boundaries.
Green Extraction Methods for Polyphenols from Plant Matrices and Their Byproducts: A Review
Authors: Ameer Kashif , Shahbaz Hafiz Muhammad , Kwon Joong‐Ho 
Published: January 2017

AbstractPolyphenols as phytochemicals have gained significant importance owing to several associated health benefits with regard to lifestyle diseases and oxidative stress. To date, the development of a single standard method for efficient and rapid extraction of polyphenols from plant matrices has remained a challenge due to the inherent limitations of various conventional extraction methods. The exploitation of polyphenols as bioactive compounds at various commercial levels has motivated scientists to explore more eco‐friendly, efficient, and cost‐effective extraction techniques, based on a green extraction approach. The current review aims to provide updated technical information about extraction mechanisms, their advantages and disadvantages, and factors affecting efficiencies, and also presents a comparative overview of applications of the following modern green extraction techniques—supercritical fluid extraction, ultrasound‐assisted extraction, microwave‐assisted extraction, pressurized liquid extraction, and pressurized hot water extraction—as alternatives to conventional extraction methods for polyphenol extraction. These techniques are proving to be promising for the extraction of thermolabile phenolic compounds due to their advantages over conventional, time‐consuming, and laborious extraction techniques, such as reduced solvent use and time and energy consumption and higher recovery rates with lower operational costs. The growing interest in plant‐derived polyphenols prompts continual search for green and economically feasible modern extraction techniques. Modern green extraction techniques represent promising approaches by virtue of overcoming current limitations to the exploitation of polyphenols as bioactive compounds to explore their wide‐reaching applications on an industrial scale and in emerging global markets. Future research is needed in order to remove the technical barriers to scale‐up the processes for industrial needs by increasing our understanding and improving the design of modern extraction operations.

Authors: Aldridge Arnie , Dowd William , Bray Jeremy 
Published: January 2017

AbstractAimsTo assess the relative impact of brief treatment (BT) compared with brief intervention (BI) on changes in substance use behavior in primary care screening programs for substance use disorders, overall and by patient severity.Design and participantsA total of 9029 patients with both baseline and follow‐up interviews were identified in the US Government Performance and Results Act (GPRA) data from October 2004 and February 2008. Using a propensity score framework, multiple generalized linear mixed models and a local linear matching method with a difference in difference estimator, patients from the BI group that resemble BT patients were used to determine the relative treatment effect of BT. A total of 3218 of these US patients with baseline and follow‐up interviews were used in the final analysis sample after the propensity score‐matching procedure (1448 patients assigned to a BI service category and 1770 assigned to a BT service category).SettingUnited States.MeasurementsDependent variables were the number of days of use in the past 30 days of any alcohol, alcohol to intoxication, illicit drugs and marijuana.FindingsThe relative impact of BT was not significant for alcohol (0.269; P > 0.1) or alcohol to intoxication (0.462; P > 0.1). BT was found to reduce the frequency of use of illicit drugs at follow‐up by 0.634 days more than BI (P < 0.05). Marijuana days were not affected significantly by assignment to BT (−0.128; P > 0.1). Higher severity patients assigned to BT had a decrease in days of illicit drug use of 1.765 (P < 0.05).ConclusionsIn the United States, brief treatment appears to have a stronger impact on reducing illicit drug use than brief intervention but is similar to brief intervention for reducing alcohol use, alcohol to intoxication and marijuana use alone.

Published: January 2017

AbstractIntroductionThe aim of the study was to assess the risk of surgery after initial conservative treatment of rectosigmoid endometriosis in relation to demographic data.Material and methodsThe study was conducted on the tertiary endometriosis referral unit, Aarhus University Hospital. Medical records, from patients seen from January 2009 onwards with a diagnosis of rectosigmoid endometriosis and more than 6 months’ follow up were audited. Demographic data, results of magnetic resonance imaging and time to secondary surgery for rectosigmoid endometriosis were registered.ResultsData on 238 patients diagnosed with rectosigmoid endometriosis were included. In all, 78 (32.8%) patients had primary surgery, 27 (11.3%) had secondary surgery and 133 (55.9%) continued conservative treatment throughout the observation period. Patients who underwent primary or secondary surgery were younger than patients continuing conservative treatment.ConclusionsIn a tertiary referral center where about half of patients with rectosigmoid endometriosis were scheduled for conservative treatment, more than 80% of these avoided surgery.
Exposure to subthreshold dose of UVR‐B induces apoptosis in the lens epithelial cells and does not in the lens cortical fibre cells
Authors: Galichanin Konstantin 
Published: January 2017

AbstractPurposeThe aim of this study was to investigate in which part of the lens in vivo exposure to subthreshold dose of UVR‐B radiation induces apoptosis.MethodsTwenty 6‐week‐old female albino Sprague‐Dawley rats were exposed to subthreshold dose (1 kJ/m2) of UVR‐B unilaterally and killed at 120 hr after exposure. Lenses were enucleated and dissected on three regions: the lens epithelium, the cortex and the nucleus. The lens nucleus then was removed. Apoptosis markers p53 and caspase 3 were used to study apoptosis in the lens regions. qRT‐PCR and Western blot were utilized to analyse the lenses.ResultsTP53 and CASP3 mRNA expressions are increased in exposed lenses, both in the lens epithelium and in the cortex regions, in relation to non‐exposed lenses. Expression of p53 protein is increased in exposed lens epithelium in relation to non‐exposed lens epithelium. Caspase 3 protein is expressed in exposed lens epithelial cells, while it is not expressed in non‐exposed lens epithelial cells. p53 and caspase 3 proteins are not expressed in either exposed nor non‐exposed lens fibre cells.ConclusionExposure to UVR‐B increases mRNA transcription of apoptosis marker p53 in vivo in both regions of the lens and of apoptosis marker caspase 3 in the lens cortex. Exposure to UVR‐B increases p53 and caspase 3 proteins expression just in the lens epithelium. In vivo exposure to subthreshold dose of UVR‐B induces apoptosis in the lens epithelial cells and does not in the lens fibre cells.

SummaryHuman monopoiesis is a tightly coordinated process which starts in the bone marrow (BM) haematopoietic stem cell (HSC) compartment and leads to the production of circulating blood mature monocytes. Although mature monocytes/macrophages have been extensively studied in both normal or inflammatory conditions, monopoiesis has only been assessed in vitro and in vivo animal models, due to low frequency of the monocytic precursors in the normal human BM. Here we investigated the transcriptional profile along normal human BM monopoiesis. Five distinct maturation‐associated stages of monocytic precursors were identified and isolated from (fresh) normal human BM through fluorescence‐activated cell sorting, and the gene expression profile (GEP) of each monocytic precursor subset was analysed by DNA‐oligonucleotide microarrays. Overall, >6000 genes (18% of the genes investigated) were expressed in ≥1 stage of BM monopoiesis at stable or variable amounts, showing early decrease in cell proliferation with increased levels of expression of genes linked with cell differentiation. The here‐defined GEP of normal human BM monopoiesis might contribute to better understand monocytic differentiation and the identification of novel monocytic candidate markers, while also providing a frame of reference for the study of monocytic maturation in both neoplastic and non‐neoplastic disease conditions involving monocytic precursor cells.
