Stagnation point flow of a nanofluid past a non-aligned stretching/shrinking sheet with a second-order slip velocity
Authors: Roşca Alin V. , Roşca Natalia C. , Pop Ioan 
Published: November 2018

Purpose
The purpose of this study is to investigate the influence of the second order slip velocity on the boundary layer stagnation point flow of a nanofluid past a non-aligned stretching/shrinking sheet.

Design/methodology/approach
Proper similarity variables are used to transform the system of partial differential equations into a system of ordinary (similarity) differential equations. This system is then solved numerically using the bvp4c solver in MATLAB software. As in the papers by Kuznetsov and Nield (2010, 2013) and Fang et al. (2009), the authors considered the stretching/shrinking parameter λ, the first-order (a1, a2) and second-order (b1) slip parameters and the Lewis number Le, Nb the Brownian parameter and Nt the thermophoresis parameter fixed at Le = 10, Nb = Nt = 0.5 when the Prandtl number Pr is fixed at Pr = 1.

Findings
Dual solutions are found as the sheet is shrunk in the horizontal direction. Stability analysis shows that the first solution is physically realizable, whereas the second solution is not practicable.

Originality/value
The present results are original and new for the study of fluid flow and heat transfer over a stretching/shrinking surface, as they successfully extend the problem considered by Wang (2008) and Lok et al. (2011) to the case of nanofluids.
Institutional environment and network competence in successful SME internationalisation
Authors: Torkkeli Lasse , Kuivalainen Olli , Saarenketo Sami , Puumalainen Kaisu 
Published: November 2018

PurposeThe purpose of this paper is to examine the impact of institutional environment on the international performance of small- and medium-sized enterprises (SMEs) and how this relationship is influenced by network competence.Design/methodology/approachThis study uses a quantitative approach. In total, 119 internationally operating Finnish SMEs from five industry sectors are sampled via a cross-sectional survey. Data are analysed through regression modelling.FindingsThe international performance of SMEs is influenced directly and indirectly by institutional drivers. The results show that network competence mediates the positive relationship between institutional drivers and international performance.Research limitations/implicationsNetwork capability development can help SMEs leverage more or less favourable institutional environments for successful internationalisation. Perceived institutional drivers directly result in higher performance, but the effect can be partially mediated by dynamic capabilities. The limitations of the study include its single-country context and the cross-sectional nature of the data.Practical implicationsSMEs should take their home countries’ institutional environments into account, but for long-term success, they should develop the ability to manage their business networks. A conducive institutional environment may help develop competence, which in turn can enable more successful internationalisation in terms of scale, scope and satisfaction.Social implicationsDecision-makers may benefit from knowing that, in addition to capabilities, an institutionally conducive environment that drives domestic SMEs towards international markets may be an antecedent of successful internationalisation in the SME sector.Originality/valueThis is one of the few studies to illustrate how network capabilities can mediate the influence of institutional factors on entrepreneurial internationalisation. It combines institutional theory and the dynamic capabilities view to explain successful SME internationalisation.
Peer-to-peer marketplaces: a study on consumer purchase behavior
Authors: Ampountolas Apostolos 
Published: November 2018

PurposeThe online travel environment continues to expand as the numerous peer-to-peer (P2P) marketplaces that comprise the “sharing economy” have also multiplied and expanded, resulting in a move from the traditional hospitality industry to a new digital ecosystem. The purpose of this paper is to examine the effects of different antecedents and the relationships between benefit factors. It does so by simulating the behavior that leads to consumer loyalty and repurchase intentions within a P2P marketplace transaction.Design/methodology/approachThe analysis is based on survey data from 456 respondents located in different regions, collected via a web-based survey questionnaire. A two-step approach employing confirmatory factor analysis, followed by structural equation modeling, was conducted to evaluate the measurement and structural models, as recommended by Anderson and Gerbing.FindingsThe findings of this study partially confirm the relationship between benefit factors (monetary, hedonic and location benefits) and consumer repurchase intentions. The benefit factors display a positive influence on consumer satisfaction, which mediates the relationship between loyalty and repurchase intentions. Hence, the study contributes to scholarly efforts to better understand why consumers choose to purchase through P2P platforms.Practical implicationsThe findings of this study can provide P2P intermediaries and hosts with the empirical evidence of consumer behavioral changes. Nowadays, in practice, consumers have the ability to compare products and offers. As such, for a consumer to remain loyal to a particular supplier, the offer must satisfy the service and experience that the consumer has in mind, as many alternative offers exist.Originality/valueThis study seeks to identify the behavioral factors that cause even loyal consumers to move from the traditional hospitality industries to P2P platforms, despite the probability of losing any loyalty benefits gained in the traditional industries.
Engaging consumers in multichannel online retail environment
Authors: Singh Shekhar , Srivastava Sandeep 
Published: November 2018

PurposeWith India becoming world’s second largest user of smartphones (Ming, 2017) and with more users adopting mobile devices for online shopping, Indian online retailers now have to manage mobile channel in addition to existing traditional channel (of computers). Hence, the purpose of this study is to investigate the mapping of product characteristics with individual channel capabilities and its effect on online consumer behaviour, so that e-tailers can create enhanced online shopping experience for consumers.Design/methodology/approachA comprehensive research model is developed on the basis of the knowledge gained from multichannel retailing and e-commerce literature. Then, the model is empirically tested, with primary data collected from 344 customers, using structural equation modelling. The data are collected from customers across two product categories: electronics and fashion.FindingsThe results reveal that perceived usefulness, perceived risk and perceived self-efficacy are important drivers of online consumer behaviour for continued usage. The multi-group analysis confirms the moderation influence of platform type for some relationships across electronics and fashion.Practical implicationsThe findings underline the importance of multichannel complementarity across electronics and fashion. The preference of mobile devices for fashion and traditional devices such as computers for electronics provides valuable insights for online retailers towards management of multichannel e-commerce ecosystem.Originality/valueIn Indian context, this is the first empirical research on online multichannel retail setting, studying the impact of diverse channel formats on different product categories. The study’s findings give empirical basis to online retailers to look out for right product–channel fit strategy for engaging consumers in the long run.
Consumers’ redemption behavior of recommended mobile coupons in social network sites
Authors: Tang Qing , Liu Fen , Liu Shan , Ma Yunfeng 
Published: November 2018

PurposeThe purpose of this paper is to explore the key factors that affect consumer redemption intention toward mobile coupons recommended in social network sites (SNS).Design/methodology/approachA research model that integrates recommendation trust, positive utilities, and negative utilities of coupon redemption is developed. With the important role of trust in social recommendation taken into consideration, the key drivers of recommendation trust were analyzed in the model. Data were collected from 210 users with mobile coupon recommendation experience in one of the largest SNS (i.e. WeChat) in China. The authors used partial least squares technique to analyze the model.FindingsRecommendation trust and positive utilities (economic benefits and perceived enjoyment) positively affect the intention of mobile coupon redemption. Perceived risk, as a negative utility, negatively influences coupon redemption intention. In addition, swift trust (structure assurance, perceived similarity, trust propensity, and expertise of the recommender), knowledge-based trust (familiarity with the retailers), and emotion-based trust (social tie strength) are key drivers that promote recommendation trust.Originality/valueWhile prior research investigated mobile coupon redemption behavior in which coupons were issued by merchants, limited research analyzed consumer responses toward mobile coupons in social recommendation. This study examines the effects of recommendation trust, positive utilities, and negative utilities on mobile coupon redemption in the context of social recommendation and recognizes the key drivers of recommendation trust.
How does collaboration between universities and R&D firms influence performance?
Authors: Lin Jun-You 
Published: November 2018

PurposeHow does university-firm collaboration affect the performance of both universities and firms? The purpose of this paper is to evaluate university-firm collaborations aimed at expanding the treatment effects of collaboration ambition on university academic performance as well as collaboration ambition focused on the firm’s production of innovation and financial performance for the top 110 US universities and the top 200 US R&D performing firms.Design/methodology/approach“Two studies, based on the three archival data sets (National Bureau of Economic Research-Rensselaer Scientific Papers Database and the Harvard Dataverse Network (DVN) US Patent Citations database and Compustat database), are undertaken in the top 110 US universities and the top 200 US R&D performing firms.” The study introduces a theoretical model that explicitly addresses collaboration diversity, number of collaborations, knowledge stock and the endogeneity problem that is generated by self-selection of collaboration ambition in university and firm’s performance.FindingsThe results suggest that the effects of adopting proactive collaboration decision on academic performance are insignificant in the firm subsample. However, more interestingly, the authors find supporting evidence of the negative impact of collaboration on university groups. The authors also find that collaboration diversity, knowledge stock and collaboration ambition lead to stronger firm performance but the number of collaborations is smaller on firm performance. Furthermore, the authors find that collaboration ambition moderates the positive effect of the number of collaborations on firm performance.Practical implicationsUniversity-firm collaboration is a multifaceted relationship, suggesting that the empirical analysis can be interpreted through the university and the firm view to enhance the understanding of the collaboration for performance creation. This study articulates the positive role of collaboration diversity, knowledge stock and collaboration ambition and the negative role of the number of collaborations on university-firm collaboration in terms of university and firm performance. Moreover, proactive collaboration ambition has the positive effect of a higher number of collaborations on firm performance. The authors conclude that policy should refrain from overly focusing on collaboration diversity, number of collaborations, knowledge stock and collaboration ambition, and the authors consider the interactions between the number of collaborations and collaboration ambition on university-firm collaboration when discussing their effects on mutual performance.Originality/valueThis study demonstrates the effects of university-firm collaboration on academic performance. In addition, the authors discuss the factors that influence collaboration to help the firm to increase its innovation and financial performance. Therefore, it would be interesting to see simultaneously how university-firm collaboration affects the performance of both partners.
Capital structure and firm performance in European SMEs
Authors: Li Kang , Niskanen Jyrki , Niskanen Mervi 
Published: November 2018

Purpose
The purpose of this paper is to investigate whether the relationship between capital structure and firm performance in small- and medium-sized enterprises (SMEs) is moderated by credit risk.

Design/methodology/approach
The authors empirically test whether an SME’s credit risk affects the SME’s relationship between capital structure and firm performance by using a 2012 cross-sectional sample of European SMEs from Austria, Belgium, Finland, France, Germany, Italy, Portugal, Spain, Sweden and the UK.

Findings
The empirical results suggest that in low credit risk SMEs, the debt ratio is negatively related to firm performance; however, this relationship is not present in high credit risk SMEs. Therefore, it is indicated that SME credit risk moderates the relationship between capital structure and firm performance.

Practical implications
The findings of the paper will enable financial managers to understand the importance of SMEs’ credit risk and will assist them in maximizing firms’ performance.

Originality/value
This paper extends the findings of previous studies by examining whether credit risk affects the relationship between capital structure and firm performance.
Development and validation of a multi-dimensional customer-based scale to measure perceptions of corporate social responsibility (CSR)
Authors: Latif Fawad , Pérez Andrea , Alam Waqar , Saqib Adeel 
Published: November 2018

PurposeBased on a review of previous literature that revealed a gap in the measurement of corporate social responsibility (CSR) from a customer perspective. The purpose of this study is to propose a multi-dimensional scale to measure customer perceptions of CSR.Design/methodology/approachUsing a systematic development process, the scale items were generated through the review of CSR literature and the opinion of academic experts. The scale was validated using data collected from 393 customers of telecom industry. Data were initially subjected to exploratory factor analysis to identify the underlying scale dimensions. Confirmatory factor analysis was also conducted to validate the scale, test for reliability, convergent and discriminant validity.FindingsThe resulting scale is compounded of 30 items that load on five dimensions: developmental, ethical, relationship-building, responsiveness and information-sharing responsibilities.Practical implicationsThe proposal of reliable measurement tools for evaluating customer perceptions is especially relevant for companies because of their significant role in influencing the design and implementation of corporate actions. The multi-dimensional scale developed in this study helps scholars and practitioners to better understand customer perceptions of the CSR actions that companies implement to improve these stakeholders’ satisfaction. In doing so, the scale is especially useful for companies to measure how well they respond to customer needs in their daily routines.Originality/valueThere is a significant lack of research into the development of reliable and valid tools to measure CSR from a customer perspective. The contribution of this study focuses on the identification of the five dimensions that determine CSR toward customers while it also provides a detailed scale to measure customer perceptions of these CSR dimensions.
Ratios of Parameters: Some Econometric Examples
Authors: Lye Jenny , Hirschberg Joe 
Published: November 2018

AbstractRatios of parameter estimates are often used in econometric applications. However, constructing confidence intervals (CIs) for these ratios can cause difficulties since the ratio of asymptotically normally distributed random variables are Cauchy distributed and thus have no finite moments. This article presents a method for the estimation of CIs based on the Fieller approach that has been shown to be preferable to the usual Delta method. Using example applications in Stata and R, we demonstrate that a few extra steps in the examination of the estimate of the ratio can provide a CI with superior coverage.
Effects of Increasing Enforcement on Financial Reporting Quality and Audit Quality
Authors: EWERT RALF , WAGENHOFER ALFRED 
Published: November 2018

ABSTRACTA widely held assumption in policy making and empirical research is that increasing the strength of public enforcement improves financial reporting quality and audit quality. This paper provides a more nuanced view. In a model with a manager who can manage earnings, a strategic auditor, and an enforcement institution, we show that enforcement and auditing are complements in a weak enforcement regime but can be substitutes in a strong regime. Although stronger enforcement always mitigates earnings management, the effects of different instruments of strengthening enforcement are ambiguous. We show that they can improve or impair financial reporting quality and audit quality, depending on production risk, accounting system characteristics, and the scope of auditing relative to enforcement.
Rebalancing the Encounter between Science Diplomacy and International Relations Theory
Authors: Kaltofen Carolin , Acuto Michele 
Published: November 2018

AbstractWhether it is in climate change negotiations, pandemic scares, security threats or sustainable development agendas, science and technology are today at the heart of international affairs. Yet there is still limited academic work that deals with the complex relationships between international diplomatic and scientific endeavours. How can we bridge this divide and possibly ‘rebalance’ the encounter between the practice of science diplomacy, its practitioner‐driven literature, and the discussions of international relations theory (IR) that underpin the study of world politics? Here we propose that this move could start from a more explicit placing of science diplomacy discussions across the IR spectrum. We pose that taking seriously science ‘diplomacy’, whilst undoing conventions around the hitherto limited ‘IR’ reading of science in its literature, would do well in establishing this reality not just as a domain of reflective practitioners, but as an effective launchpad for international theorizing as much as more academically‐driven practice.
Science Diplomacy: Introduction to a Boundary Problem
Authors: Kaltofen Carolin , Acuto Michele 
Published: November 2018

AbstractScientific advancements, their application through technological development, and world politics have been long acknowledged as affecting each other, and are today more than ever at the heart of global policy. Speaking of ‘science diplomacy’ as the encounter of world politics and the world of science at the heart of these advancements might be a unique window into our time. This potential is what prompts this special issue to gather views from a variety of scholarly and practical viewpoints, linking the well‐established world of reflective practitioners in science diplomacy to the growing field of international relations (IR) scholars theorising this realm. Can speaking of ‘science diplomacy’ situate our attention at the crossroads of science and international relations, and spur greater appreciation for their intersections? This introduction to the special issue summarises the rise of science diplomacy as field of inquiry, and casts questions as to the need to advance, where not reform, these conceptualisations. It defines science diplomacy as a ‘boundary problem’ par excellence and emphasises its ‘productive tension’ that emerges between the various ways of knowing of actors belonging to ‘different social worlds’, seeking to gather a productive tension of views on this theme in the issue.
CSIRTs and Global Cybersecurity: How Technical Experts Support Science Diplomacy
Authors: Tanczer Leonie Maria , Brass Irina , Carr Madeline 
Published: November 2018

AbstractOngoing efforts by state actors to collaborate on addressing the challenges of global cybersecurity have been slow to yield results. Technical expert communities such as Computer Security and Incident Response Teams (CSIRTs) have played a fundamental role in maintaining the Internet's functional structure through transnational collaboration. Responsible for security incident management and located in diverse constituencies, these coordination centres engage in joint responses and solve day‐to‐day cybersecurity problems through diverse national, regional and international networks. This article argues that CSIRTs form an epistemic community that engages in science diplomacy, at times navigating geopolitical tensions in a way that political actors are not able to. Through interviews with CSIRT representatives, we explain how their collaborative actions, rooted in shared technical knowledge, norms and best practices, contribute to the advancement of international cooperation on cybersecurity.

Published: November 2018

AbstractBackgroundChronic rhinosinusitis with nasal polyposis (CRSwNP) is a type 2‐mediated inflammatory disease associated with significant clinical, social, and economic burdens and high unmet therapeutic need. Dupilumab, a fully human monoclonal antibody targeting the interleukin‐4 receptor α (IL‐4Rα) subunit, demonstrated efficacy and acceptable safety in CRSwNP and other type 2 diseases (eg, atopic dermatitis and asthma). We now report the local effects of dupilumab on type 2 inflammatory biomarkers in nasal secretions and nasal polyp tissues of patients with CRSwNP in a randomized, placebo‐controlled, phase 2 trial (NCT01920893).MethodsCytokines, chemokines, and total immunoglobulin E (IgE) levels were measured using immunoassay techniques in nasal secretions and nasal polyp tissue homogenates of CRSwNP patients receiving dupilumab 300 mg or placebo weekly for 16 weeks.ResultsWith dupilumab, type 2 biomarker concentrations decreased in nasal secretions (least squares mean area under the curve from 0 to 16 weeks for the change from baseline) vs placebo for eotaxin‐3 (−30.06 vs −0.86 pg/mL; P = 0.0008) and total IgE (−7.90 vs −1.86 IU/mL; P = 0.022). Dupilumab treatment also decreased type 2 biomarker levels in nasal polyp tissues at Week 16 vs baseline for eosinophilic cationic protein (P = 0.008), eotaxin‐2 (P = 0.008), eotaxin‐3 (P = 0.031), pulmonary and activation‐regulated chemokine (P = 0.016), IgE (P = 0.023), and IL‐13 (P = 0.031).ConclusionsDupilumab treatment reduced multiple biomarkers of type 2 inflammation in nasal secretions and polyp tissues of patients with CRSwNP, demonstrating that antagonism of IL‐4Rα signaling suppresses IL‐4‐/IL‐13‐dependent processes, such as mucosal IgE formation, as well as the expression of chemokines attracting inflammatory cells to the nasal mucosa.
