How does coopetition affect radical innovation? The roles of internal knowledge structure and external knowledge integration
Authors: Chen Huanhuan , Yao Yanhong , Zan Ao , Carayannis Elias G. 
Published: July 2020

PurposeBuilding on the resource- and knowledge-based views, this paper aims to explore how coopetition affects radical innovation and the roles of knowledge structure and external knowledge integration in the relationship between coopetition and radical innovation.Design/methodology/approachThis study proposes a research model to examine the mediating role of external knowledge integration on the coopetition-radical innovation link, where the mediation is moderated by the firm’s knowledge structure (including component knowledge and architectural knowledge). The authors use regression and bootstrapping to test the proposed model with survey data from 241 Chinese technology firms.FindingsThis study finds that coopetition positively affects radical innovation and the effect is fully mediated by external knowledge integration. Additionally, component knowledge negatively moderates the coopetition-external knowledge integration link and architectural knowledge positively moderates this relationship. Further, the mediating effect of external knowledge integration is also moderated by component knowledge and architectural knowledge.Practical implicationsFirms should engage in coopetition to promote radical innovation. Further, it is necessary for firms to appropriately manage coopetition according to their internal knowledge structure.Originality/valueThis study explains why scholars have different ideas about the relationship between coopetition and radical innovation by exploring the mediating role of external knowledge integration and the moderating effect of knowledge structure. Firms possess increased possibilities for knowledge leakage and partner opportunism with high levels of component knowledge, which will reduce the positive effect coopetition on external knowledge integration; thus, they are less likely to realize radical innovation. Instead, firms possess increased opportunities for resource sharing with high levels of architectural knowledge, thus improving the positive effect coopetition on external knowledge integration and they are more likely to achieve radical innovation.

Published: July 2020

PurposeThis study aims to investigate the trends in existing studies in the field of ethnic entrepreneurship in the context of growing markets in terms of definitions, theories, themes, methodologies and settings.Design/methodology/approachThis study used bibliometric analysis and used Publish or Perish software with Google Scholar as the database. A total of 183 articles published in 122 journals from 1988 to 2018 were selected. This study used systematic data to reveal trends in growing markets and qualitative inductive analysis to define relevant themes within the topic.FindingsThe results show that ethnic entrepreneurship is defined as involving immigrants from developing countries. From a theoretical point of view, socio-cultural theories, socio-economic theories and combinations of both have been used to explain the phenomenon. Six research themes have been developed indicating potential explorative and exploitative research themes. This study identified the dominance of the qualitative approach in ethnic entrepreneurship research and found that the typical research subjects are Asian immigrants, especially Chinese, in developed countries. The articles reviewed were mainly conducted in developed countries (68.85%) and a lesser portion in developing countries (13.66%), particularly Asian countries.Practical implicationsThis study provides future directions for research on ethnic entrepreneurship, such as gender studies of ethnic entrepreneurs and factors affecting the opening of new businesses in new locations.Originality/valueThis study reveals trends in the ethnic entrepreneurship field based on the country in which the study was conducted, the definition of ethnic entrepreneurship, the theories, the research themes, the methodologies, the research setting and the ethnicity studied. It also used the framework of input–process–output to establish a generic road map of the ethnic entrepreneurship research area.

Authors: Sari Dessy Kurnia , Suziana Suziana , Games Donard 
Published: July 2020

Purpose
This paper aims to investigate the effects of informativeness, entertainment and credibility of social media on the perceived value of advertising for Muslim millennial parents. It evaluates the impact of these variables on brand awareness and purchase intention.

Design/methodology/approach
This study uses a mixed-method analysis with two stages. In the first stage, information from social media was collected. The second stage involved an online survey of 210 Muslim millennial parents. Structural equation modeling-partial least squares was used to test the study’s prediction.

Findings
The results showed that informativeness, entertainment and credibility of the message significantly influence Muslim millennial parents’ perceived value of social media advertising. These aspects also have a significant effect on brand awareness and purchase intention. The parents appreciate entertainment most, followed by the informativeness and credibility of the message.

Practical implications
This study offers new insights on Muslim millennial parents as a new segment in the market. Social media advertising is the most appropriate strategy for approaching this segment, and therefore, should be given much attention by marketers. The message created needs to be informative, entertaining and credible. It should consider culture, Islamic values and tradition.

Originality/value
The study contributes to the evaluation of a new trend for Muslim millennials as young parents. The tendency to spend more time using social media as the primary source of information is evaluated. Additionally, this study gives marketers a better understanding of Muslim millennial parents, especially in a collective society.
“I” seek differentiation and “we” seek assimilation: the impact of self-expressive customization on consumers’ willingness to pay a premium

Published: July 2020

PurposeCustomization, as a crucial way to meet the heterogeneous demand of individuals, exists two fundamental and competing motivations, namely, assimilation and uniqueness. Based on optimal distinctiveness theory, this paper aims to validate the interactive effect of self-expressive customization types (i.e. customization to express individual identity and customization to express a shared identity) and self-construal on consumers’ willingness to pay a premium (WPP).Design/methodology/approachTwo studies were conducted to provide empirical support for all proposed hypotheses. The first study (n= 151) uses a hypothetical scenario of a basketball game to test the interaction effect of self-expressive customization and self-construal. The second study (n= 184) assumes a scenario of designing a t-shirt or a uniform to examined the moderated mediating role of consumer-product identification.FindingsThe results reveal that independent (vs interdependent) self-construal will have stronger consumer-product identification for customization to express an individual identity (vs customization to express a shared identity), thus generating a higher WPP. Also, perceived task difficulty is the boundary condition of the research model.Research limitations/implicationsThis paper makes insightful contributions to the customization literature by strengthening the identity signals of customization and exploring the psychological mechanism and the boundary conditions.Originality/valueThis research is one of the first few empirical studies to examine the impact of self-expressive customization on consumers’ WPP via the identification with the focal object. This paper not only expands the literature of self-expressive customization but also provides a new research direction for the research of person-object interaction in marketing.
CDS-based implied probability of default estimation
Authors: Abid Amira , Abid Fathi , Kaffel Bilel 
Published: July 2020

Purpose
This study aims to shed more light on the relationship between probability of default, investment horizons and rating classes to make decision-making processes more efficient.

Design/methodology/approach
Based on credit default swaps (CDS) spreads, a methodology is implemented to determine the implied default probability and the implied rating, and then to estimate the term structure of the market-implied default probability and the transition matrix of implied rating. The term structure estimation in discrete time is conducted with the Nelson and Siegel model and in continuous time with the Vasicek model. The assessment of the transition matrix is performed using the homogeneous Markov model.

Findings
The results show that the CDS-based implied ratings are lower than those based on Thomson Reuters approach, which can partially be explained by the fact that the real-world probabilities are smaller than those founded on a risk-neutral framework. Moreover, investment and sub-investment grade companies exhibit different risk profiles with respect of the investment horizons.

Originality/value
The originality of this study consists in determining the implied rating based on CDS spreads and to detect the difference between implied market rating and the Thomson Reuters StarMine rating. The results can be used to analyze credit risk assessments and examine issues related to the Thomson Reuters StarMine credit risk model.

Published: July 2020

Purpose
The purpose of this paper aims to assess the intake of dietary selenium among Jordanian adults in Madaba Governorate.

Design/methodology/approach
The authors conducted a cross-sectional study in Madaba Governorate. Convenience sampling was done at Madaba Governorate for this study. The subjects comprised 500 subjects (325 women and 175 men) aged from 18 to 60 years. A 24-h recall (24-HR) and Food Frequency Questionnaire (FFQ) were used to estimate the selenium intake in the studied population.

Findings
Mean of dietary selenium was more than the recommended amount by at least 2.5-fold in both methods FFQ and 24-HR (p = 0.004), while no significant difference was observed in selenium consumption per day for women and men respectively using FFQ. The results indicated that selenium consumption is higher than the RDA among Madaba population. A moderate correlation was found between both methods for all subjects, women and men, respectively (p < 0.05).

Originality/value
The authors conclude that the selenium intake in Jordanian population is significantly above the RDA. However, future studies are required to correlate this high intake with health benefits and exclude toxic effects of Selenium.
Equitable student success via library support for textbooks
Authors: Wimberley Laura , Cheney Elizabeth , Ding Yi 
Published: July 2020

PurposeThe cost of course materials to the individual student has increased over the past decade, contributing to educational inequity. Open educational resources (OERs) may be a solution and research validates their positive impact on student success outcomes (Colvardet al., 2018; Feldsteinet al., 2012). Few studies, however, examine the role that library collections play in addressing course materials cost and student success. This paper aims to investigate whether materials costs are a significant factor in course pass rate and whether the library has a positive impact on pass rates.Design/methodology/approachUsing required texts listed in syllabi for select undergraduate courses at California State University, Northridge (CSUN), the authors compare course materials costs for each course to the pass rate. The authors then measure the impact of course materials cost on the achievement gap between Pell Grant eligible and non-eligible students.FindingsThis study confirms previous research indicating that reduced course materials costs have a measurable impact on student success, in that the total minimum cost of required materials has a statistically significant effect on the percentage of students who pass a course. However, course reserves slightly increase the disparity between high-income and low-income students, suggesting that course reserves are a less effective way of supporting the latter compared to OERs.Originality/valueThis study is unique in examining the effect of the cost of course materials on students, regardless of the source of cost reductions. Most literature focuses on the qualitative efficacy of OERs instead of measured impact or the relationship between the cost of course materials and student success. The authors investigate the connection between OERs, library engagement and student success.
Self‐fulfilling patience
Authors: Gong Liutang , Wang Wei 
Published: July 2020

AbstractThis paper explores macroeconomic implications of investment in patience in a standard neoclassical growth model with Becker‐Mulligan endogenous time preferences. The endogenous discount rate acts as a new margin for inter‐temporal decisions, in addition to the standard margin that hinges on the marginal return of capital. This time preference margin alters the equilibrium dynamics and stability of the neoclassical growth model substantially. When the discount rate is positive, there may exist multiple steady states that are either saddle‐point stable or unstable. When the discount rate is negative, the unique steady state is locally indeterminate due to self‐fulfilling patience investment. Interestingly, the existence of the local indeterminacy does not need any externality. When the discount rate is zero, various types of bifurcations can happen, leading to rich equilibrium dynamics such as limit cycles and chaos. We show that opening up the closed economy can cause aggregate instability.
Formal versus Informal System to Mitigate Non‐point Source Pollution: An Experimental Investigation
Authors: Nguyen Kiet T. 
Published: July 2020

AbstractWater pollution caused by aquaculture or agricultural activities negatively affects both the activity and downstream areas. A number of other upstream‐downstream problems (e.g. water use, industrial/municipal water source pollution, salinity zoning problems) are examples of similar negative externalities. Non‐point source pollution, which is either prohibitively costly or impossible to observe, is more feasible to identify, and hence mitigate at the aggregate level. We study experimentally the efficacy of two possible management systems: a centralised external, formal government‐led monitoring and control system; a self‐governing communication and informal system, both designed to manage shrimp farming, which generates a non‐point source pollution with upstream‐downstream externalities. Our results suggest that local communication and control outperforms the external monitoring and certification agency. These results, in conjunction with other relevant research, suggest that informal regulation and self‐governance among shrimp farmers can be highly successful in tackling the pollution problem.
Mitigation effect of sodium alginate on acrylamide formation in fried potato chips system based on response surface methodology
Authors: Liu Hui , Li Xuenan , Yuan Yuan 
Published: July 2020

AbstractAcrylamide is a known neurotoxin and probable carcinogen in humans. Researchers reported that foods rich in carbohydrates could generate high amounts of acrylamide at high temperatures. In recent years, hydrocolloids are applied to reduce acrylamide in thermally processed foods and the effect has been well proved. The present work was to investigate the effect of sodium alginate as the coating agent on acrylamide formation in fried potato chips by a Box‐Behnken design. The optimized processing conditions were: sodium alginate at the concentration of 1.34%, frying time at 4.38 min, and frying temperature at 179 °C. The corresponding inhibition rate of acrylamide was 76.59%. Compared to the control group, the oil absorption of coating chips decreased significantly, whereas the addition of sodium alginate did not affect the quality of potato chips. Scanning electron microscope analysis revealed that coating with sodium alginate could effectively prevent oil uptake, which might contribute to acrylamide mitigation. Overall, sodium alginate significantly mitigated acrylamide formation in fried potato chips.Practical ApplicationSodium alginate could significantly reduce acrylamide formation in fried potato chips systems. Sodium alginate may therefore be a new mitigation strategy for acrylamide formation in commercial fried foods without prejudice to main quality properties valued by consumers.

Published: July 2020

SummaryAcetogens such as Clostridium ljungdahlii can play a crucial role reducing the human CO2 footprint by converting industrial emissions containing CO2, CO and H2 into valuable products such as organic acids or alcohols. The quantitative understanding of cellular metabolism is a prerequisite to exploit the bacterial endowments and to fine‐tune the cells by applying metabolic engineering tools. Studying the three gas mixtures CO2 + H2, CO and CO + CO2 + H2 (syngas) by continuously gassed batch cultivation experiments and applying flux balance analysis, we identified CO as the preferred carbon and electron source for growth and producing alcohols. However, the total yield of moles of carbon (mol‐C) per electrons consumed was almost identical in all setups which underlines electron availability as the main factor influencing product formation. The Wood–Ljungdahl pathway (WLP) showed high flexibility by serving as the key NAD+ provider for CO2 + H2, whereas this function was strongly compensated by the transhydrogenase‐like Nfn complex when CO was metabolized. Availability of reduced ferredoxin (Fdred) can be considered as a key determinant of metabolic control. Oxidation of CO via carbon monoxide dehydrogenase (CODH) is the main route of Fdred formation when CO is used as substrate, whereas Fdred is mainly regenerated via the methyl branch of WLP and the Nfn complex utilizing CO2 + H2. Consequently, doubled growth rates, highest ATP formation rates and highest amounts of reduced products (ethanol, 2,3‐butanediol) were observed when CO was the sole carbon and electron source.

Published: July 2020

AbstractAim/IntroductionAlthough anti‐centromere antibody (ACA)+ Sjögren's syndrome (SS) is considered a subtype of SS, it was not included in the recent American College of Rheumatology/ European League Against Rheumatism (ACR/EULAR) SS classification criteria. ACA+ patients without anti‐SS‐A/Ro antibodies require salivary gland histopathology to fulfill the ACR/EULAR criteria for diagnosis of SS. We reviewed salivary gland histology among ACA+ patients referred for the diagnosis of SS using the ACR/EULAR and Japanese criteria which does not require biopsy.MethodData from 147 ACA+ patients with dry eyes and/or mouth who visited our department were retrospectively analyzed. Clinical, immunological, and histological data were collected and statistically analyzed.ResultSixty‐five patients (44%) had undergone labial salivary gland biopsy. The frequency of dry mouth was higher in ACA+ patients who had undergone labial salivary gland biopsy than in those who had not (P = .046), while there were no differences in biopsy rates between patients with and without sclerodactyly (P = .51). According to the current ACR/EULAR classification criteria, Greenspan grade of 3 or 4 for labial salivary gland histopathology is required in patients without anti‐SS‐A/Ro antibody for the diagnosis of SS. Four patients with Greenspan grades <3 and anti‐SS‐A/Ro antibody met the criteria for SS. In 54 patients in which the ACR/EULAR criteria were met, 53 patients were diagnosed with SS using the Japanese criteria.ConclusionIn ACA+/anti‐SS‐A/Ro– antibody patients, agreement between ACR/EULAR and Japanese criteria sets was excellent. For easily classifying ACA+ patients as SS cases, salivary gland biopsy should be performed in ACA+ patients with dry symptoms to identify ACA+ patients.

AbstractIdiopathic pulmonary fibrosis (IPF) is a progressive disease thought to result from impaired lung repair following injury and is strongly associated with aging. While vascular alterations have been associated with IPF previously, the contribution of lung vasculature during injury resolution and fibrosis is not well understood. To compare the role of endothelial cells (ECs) in resolving and non‐resolving models of lung fibrosis, we applied bleomycin intratracheally to young and aged mice. We found that injury in aged mice elicited capillary rarefaction, while injury in young mice resulted in increased capillary density. ECs from the lungs of injured aged mice relative to young mice demonstrated elevated pro‐fibrotic and reduced vascular homeostasis gene expression. Among the latter, Nos3 (encoding the enzyme endothelial nitric oxide synthase, eNOS) was transiently upregulated in lung ECs from young but not aged mice following injury. Young mice deficient in eNOS recapitulated the non‐resolving lung fibrosis observed in aged animals following injury, suggesting that eNOS directly participates in lung fibrosis resolution. Activation of the NO receptor soluble guanylate cyclase in human lung fibroblasts reduced TGFβ‐induced pro‐fibrotic gene and protein expression. Additionally, loss of eNOS in human lung ECs reduced the suppression of TGFβ‐induced lung fibroblast activation in 2D and 3D co‐cultures. Altogether, our results demonstrate that persistent lung fibrosis in aged mice is accompanied by capillary rarefaction, loss of EC identity, and impaired eNOS expression. Targeting vascular function may thus be critical to promote lung repair and fibrosis resolution in aging and IPF.
