New evidence on accelerator performance based on funding and location
Authors: Cánovas-Saiz Lydia , March-Chordà Isidre , Yagüe-Perales Rosa Maria 
Published: April 2020

PurposeSeed accelerators (SAs) appear as a more advanced version of business incubators. These for-profit organizations in exchange of equity, help setting new start-ups by providing mentoring and funding during its first months. Due to their emergent nature, the impact and expectations of SAs remains largely unknown. Therefore, the purpose of this study is to throw new light on this field by empirically assessing for the first time the performance and prospects of these organizations through a survey of 116 SAs.Design/methodology/approachA model based on the Business Incubators literature is built with four categories covering size, location, age and profitability variables, leading to two hypotheses to be tested empirically over a survey of 116 SAs.FindingsSome remarkable findings arise after implementation of both bivariate and multivariate analysis. The results confirm a higher size and performance in the US and in the oldest SAs at statistically significant levels.Research limitations/implicationsThe study is not free from limitations but the findings make a contribution to the still scarce existing literature on SAs, and provide some managerial implications to their stockholders, to investors and to entrepreneurs.Practical implicationsThe findings concerning performance indicators are especially helpful for investors, primarily concerned with the percentage return on investment factor, the period and the investment rounds needed to achieve exit. Another key issue is the SA's role as an employment seedbed. At first glance, the amount of employment, both overall and per company, might seem small given the young age of these firms. The impact of SAs on the generation of new employment is difficult to measure as it usually takes place in further stages of development of the tenant companies, the so-called scale-up process. Nonetheless, at present, the number of new companies being born is remarkable and, in terms of employment, the results are indeed promising. Our findings also offer important implications for entrepreneurs, venture investors and policy-makers. To entrepreneurs, our findings offer insight on the expectations to hold in the accelerator programs.Social implicationsFor policy-makers and would-be accelerator founders, our results support the idea shared in the literature that accelerators can be an effective entrepreneurial intervention, even in small entrepreneurial ecosystems, compared to the strongest entrepreneurial hubs (Hallen et al., 2017).Originality/valueSAs are a very recent phenomenon which is blooming all over the world, especially in developed countries. SAs are therefore considered a key agent in the prospects of any entrepreneurial ecosystem. However, no studies have so far analysed the impact and performance of this emerging instrument. This is precisely the main purpose of this paper, to offer for the first time an approximate and exploratory assessment on the impact and prospects of SAs, based on a database.
Effect of monetary policy on bank risk: does market structure matter?
Authors: Hussain Muntazir , Bashir Usman , Bilal Ahmad Raza 
Published: April 2020

PurposeThe purpose of this paper is to investigate the risk-taking channel of monetary policy transmission in the Chinese banking industry. This study also investigates the role of various other factors in the risk-taking channel.Design/methodology/approachThis study used panel data from 2000 to 2012, and a dynamic panel model (Difference GMM) was applied.FindingsThe empirical findings of this paper suggest that loose monetary policy rates increase bank risk-taking. Unlike previous studies, the results of this paper suggest that the bank-specific factors (size, liquidity and capitalization) do not significantly affect the risk-taking channel. However, the market structure does have a stabilizing effect on monetary policy transmission and the risk-taking channel. Higher market power weakens the risk-taking channel of monetary policy transmission.Practical implicationsOf significance to the policymakers' point of view is that loose monetary policy induces banks to take excessive risks. However, such effects can be mitigated by encouraging a proper level of market power in banking markets.Originality/valueThis study investigated the risk-taking channel of monetary policy transmission for the Chinese banking industry. Due to the unique features of the People's Bank of China (PBC, Central Bank of China) policy, this study also contributes to the literature by comparing price-based and quantity-based monetary policy tools and their effectiveness in financial stability and monetary policy transmission. Furthermore, the role of market structure is also investigated in the risk-taking channel.
Reverse decoupling: Ukrainian case of healthcare financing system reform
Authors: Vakulenko Veronika , Bourmistrov Anatoli , Grossi Giuseppe 
Published: April 2020

PurposeThe purpose of this paper is to explore inter-organizational interactions that might result in prolonged decoupling between central governments' ideas and local governments' practices during the reform of an institutional field (i.e. healthcare).Design/methodology/approachThe paper is based on a qualitative study of the centrally directed reform of the healthcare financing system in Ukraine and focusses on practices and reform ideas from 1991 to 2016.FindingsThe findings show that, for more than 25 years, local governments, as providers of healthcare services, faced two major problems associated with drawbacks of the healthcare financial system: line-item budgeting and fragmentation of healthcare funds. Over 25 years, central government's attempts to reform the healthcare financing system did not comprehensively or systematically address the stated problems. The reformers' ideas seemed to focus on creating reform agendas and issuing new laws, instead of paying attention to challenges in local practices.Practical implicationsThis article has two main points that are relevant for practitioners. First, it calls for greater involvement from local actors during all stages of public sector reforms, in order to ensure the relevance of developed reform strategies. Second, it points to potential challenges that central governments may face when conducting healthcare financing system reforms in transitional economies.Originality/valueThe paper's contribution is twofold: it outlines reasons for problematic implementation of healthcare financing system reform in Ukraine and explains them through a “reverse decoupling” concept.

Authors: Ennaji Fatima Zohra , El Fazziki Abdelaziz , El Alaoui El Abdallaoui Hasna , Benslimane Djamal , Sadgal Mohamed 
Published: April 2020

PurposeThe purpose of this paper is to bring together the textual and multimedia opinions, since the use of social data has become the new trend that enables to gather the product reputation traded in social media. Integrating a product reputation process into the companies' strategy will bring several benefits such as helping in decision-making regarding the current and the new generation of the product by understanding the customers’ needs. However, image-centric sentiment analysis has received much less attention than text-based sentiment detection.Design/methodology/approachIn this work, the authors propose a multimedia content-based product reputation framework that helps in detecting opinions from social media. Thus, in this case, the analysis of a certain publication is made by combining their textual and multimedia parts.FindingsTo test the effectiveness of the proposed framework, a case study based on YouTube videos has been established, as it brings together the image, the audio and the video processing at the same time.Originality/valueThe key novelty is the implication of multimedia content in addition of the textual one with the goal of gathering opinions about a certain product. The multimedia analysis brings together facial sentiment detection, printed text analysis, opinion detection from speeches and textual opinion analysis.
“When I saw my peers annotating”
Authors: Kalir Jeremiah Holden , Morales Esteban , Fleerackers Alice , Alperin Juan Pablo 
Published: April 2020

Purpose
Social annotation (SA) is a genre of learning technology that enables the annotation of digital resources for information sharing, social interaction and knowledge production. This study aims to examine the perceived value of SA as contributing to learning in multiple undergraduate courses.

Design/methodology/approach
In total, 59 students in 3 upper-level undergraduate courses at a Canadian university participated in SA-enabled learning activities during the winter 2019 semester. A survey was administered to measure how SA contributed to students’ perceptions of learning and sense of community.

Findings
A majority of students reported that SA supported their learning despite differences in course subject, how SA was incorporated and encouraged and how widely SA was used during course activities. While findings of the perceived value of SA as contributing to the course community were mixed, students reported that peer annotations aided comprehension of course content, confirmation of ideas and engagement with diverse perspectives.

Research limitations/implications
Studies about the relationships among SA, learning and student perception should continue to engage learners from multiple courses and from multiple disciplines, with indicators of perception measured using reliable instrumentation.

Practical implications
Researchers and faculty should carefully consider how the technical, instructional and social aspects of SA may be used to enable course-specific, personal and peer-supported learning.

Originality/value
This study found a greater variance in how undergraduate students perceived SA as contributing to the course community. Most students also perceived their own and peer annotations as productively contributing to learning. This study offers a more complete view of social factors that affect how SA is perceived by undergraduate students.

Published: April 2020

PurposeTo decrease wear and friction, zinc dialkyldithiophosphate (ZDDP) has been used in engine oil for several decades, but the mechanism of the tribofilm formation is still unclear. The purpose of this study is to characterize the chemical details of the tribofilm by using high-resolution approaching.Design/methodology/approachAn ISO VG 100 mineral oil mixed with ZDDP was used in sliding tests on cylindrical roller bearings. Tribofilm formation was observed after 2 h of the sliding test. X-ray photoelectron spectroscopy (XPS) and atom probe tomography (APT) were used for chemical analysis of the tribofilm.FindingsThe results show that the ZDDP tribofilm consists of the common ZDDP elements along with iron oxides. A considerable amount of zinc and a small amount of sulfur were observed. In particular, an oxide interlayer with sulfur enrichment was revealed by APT between the tribofilm and the steel substrate. The depth profile of the chemical composition was obtained, and a tribofilm of approximately 40 nm thickness was identified by XPS.Originality/valueA sulfur enrichment at the interface is observed by APT, which is beneath an oxygen enrichment. The clear evidence of the S interlayer confirms the hard and soft acids and bases principle.Peer reviewThe peer review history for this article is available at:https://publons.com/publon/10.1108/ILT-01-2020-0035/

Design/methodology/approach
The qualitative research method has been used because of a deep and rich analysis of the studied network. The study also provides an overview of finding and forming of partners and details of collaborations in the network, including partner’s goals from network entry, initial negotiations between members, business plan, shared resources and final results are expressed. The data used in this study has been collected by a totally seven semi-structured interviews. To analyze the collected data by open coding, the MAXQDA12 software was used and the basic concepts were identified and were categorized based on their similarities.

Findings
The studied network was identified as a strategic alliance. Details of finding, forming and performing of the studied network were explained. In total, 4 collaboration models and 28 different challenges in the network creation process were identified. In total, 28 different challenges were divided into 7 categories (based on their existence or absence in each of the 4 identified collaboration models). In total, seven categories of challenges were analyzed completely and the relations between challenges and partners of collaboration models were studied.

Originality/value
The collaboration network studied in this research involves several technological collaborations among different actors. Saadat, as the hub of this network, has been involved in all these collaborations, and other members have joined the network in accordance with network requirements and their capabilities. This network has been formed and developed with the aim of developing and producing various modules of vital signs monitoring since 2009. Some of the collaborations in this network, which are for production of a specific module and require long-term collaboration between the partners (such as the production of electrocardiograph or heart attack rapid diagnostic module), continue to be ongoing and some of them that focus on research and development or acquisition of technical knowledge (such as academic collaboration) after the specified result has been ended.

Thermo-diffusion of solid cylinders based upon refined dual-phase-lag models
Authors: Zenkour Ashraf M. 
Published: April 2020

PurposeThe thermo-diffusion analysis of an isotropic cylinder under thermal flux and chemical potential impacts has been discussed. Improvements of Green and Naghdi generalized thermoelasticity theory have been proposed.Design/methodology/approachSome models with and without energy dissipation have been presented as well as the simple forms of Green–Naghdi (G–N) theories. These novel multi- and single-/dual-phase-lag models are presented to investigate the thermo-diffusion of the solid cylinder. The closed-form solution of thermo-diffusion governing equations of solid cylinder has been obtained to deduce all field variables.FindingsA comparison study between the simple G–N II and III models and their improved models has been presented. The validations of outcomes are acceptable and so benchmarks are reported to help other investigators in their future comparisons.Originality/valueThe modified Green and Naghdi theories of types II and III are presented to get novel and accurate models of single- and dual-phase-lag of multiterms. The heat of mass diffusion equation as well as the constitutive equations for the stresses and chemical potential of a solid cylinder is added to the present formulation. The system of three differential coupled equations is solved, and all field variables are obtained for the thermal diffusion of the solid cylinder. Some validation examples and applications are presented to compare the simple and modified Green and Naghdi theories of types II and III. Sample plots are illustrated along the radial direction of the solid cylinder. Some results are tabulated to serve as benchmark results for future comparisons with other investigators. The reported and illustrated results show that the simple G–N II and III models yield the largest values of all field quantities. The single-phase-lag models give the smallest values. However, the dual-phase-lag model yields results that are intermediate between those of the simple and single-phase-lag G–N models.
Bounded rationality in a P2P lending market
Authors: Kim Dongwoo 
Published: April 2020

PurposeThis study seeks to provide a systematic analysis of bounded rationality expressed by individual lenders in a Peer-to-peer (P2P) lending market.Design/methodology/approach26,383 personal loan listings collected from Moneyauction in Korea, were analyzed with binary logit regression. 6 hypothesis based on bounded rationality theory were constructed and tested. Binary logit regression was employed as both dependent variables have binary characteristics and can thus be assigned values equal to 0 or 1.FindingsThe results confirm that individual P2P lenders make their funding decisions based on bounded rationality, arousing from cognitive limitations, incomplete information, and time constraints.Research limitations/implicationsBy adopting the theory of bounded rationality, this study attempts to prepare the theoretical background for an explanation of the decision behavior of individual lenders in a P2P lending market.Practical implicationsThe findings of this research emphasize the importance of the platform provider's role to facilitate the sustainable market growth of P2P lending as an alternative form of finance. As the rationality of individual lenders is bounded during their decision-making process according to the research findings, the platform provider must continuously adjust their decision criteria by referencing the cumulative loan repayment data.Originality/valueThis study attempts to identify for the first time the suboptimal decision making by individual lenders in a P2P lending market on the basis of bounded rationality theory.
Testing deviations from PPP and UIP: evidence from BRICS economies
Authors: Prabheesh K.P. , Garg Bhavesh 
Published: April 2020

Purpose
This paper aims to investigate the interrelations between purchasing power parity (PPP) and uncovered interest parity (UIP) in BRICS economies, namely, Brazil, Russia, India, China and South Africa, by checking the validity of the capital-enhanced equilibrium exchange rate (CHEER) approach. Further, this study tests whether the CHEER results are data frequency-dependent.

Design/methodology/approach
The present study uses monthly data ranging from 1997M01 to 2016M12 and considers the US economy as the representative foreign country. The study uses structural break unit root test and structural break cointegration technique to test the presence of economic relationships between nominal exchange rates and each of the price and interest rate differentials. Then, the study examines the validity of the CHEER approach by testing the appropriate theoretical restrictions.

Findings
The cointegration results suggest the existence of two cointegrating vectors representing UIP and PPP conditions. For all countries, the data appear to support the hypothesis that the system contains UIP and PPP relations. However, each of the international parity hypotheses is strongly rejected when formulated in isolation and jointly, leading to repudiation of the CHEER validity. Further, it is found that the results are data frequency-dependent and suggest that higher frequencies should be used as they provide additional information.

Originality/value
First, the literature on equilibrium exchange rates in BRICS economies is scanty. BRICS economies are large-emerging economies and one of the fastest growing economies and thus entail an empirical enquiry on their exchange rates. Second, the empirical application has mainly used monthly data to test the validity of the CHEER approach. However, data frequencies could affect the results. To the best of the authors’ knowledge, this study is the first to check data frequency-dependency in examination of the CHEER approach.
