Influence of failure factors on entrepreneurial resilience in Angolan micro, small and medium-sized enterprises
Authors: Franco Mário , Haase Heiko , António Dalne 
Published: April 2020

Purpose
The purpose of this study is to analyse the influence of failure factors on entrepreneurial resilience in micro-, small- and medium-sized enterprises (MSMEs).

Design/methodology/approach
To achieve this goal, a quantitative and cross-sectional study was carried out. Using a snowball sampling technique, 133 Angolan MSMEs founders responded to a questionnaire.

Findings
The results indicate that entrepreneurs attribute the failure of their activities to financial and external environmental factors such as the economic crisis and changes in the country’s laws. However, these entrepreneurs are considered resilient, as they have enough capacity to resist the national market and have a strong sense of optimism.

Practical implications
Based on the empirical evidence, this study shows that the failure factors of the MSMEs studied have a significant influence on some of the dimensions of entrepreneurial resilience. At the practical level, the study can be also seen as a tool to support decision making in allocating resources to improve entrepreneurial resilience in developing economies.

Originality/value
This study contributes to the field of research on MSMEs in an innovative way, through triangulation of the factors of business failure and entrepreneurial resilience. Furthermore, it makes some contributions to developing the theory in entrepreneurship, which has been associated with various studies about business failure.
Calculation method for comprehensive damping of ball bearings based on multigrid method
Authors: Sun Peng , Chen Weifang , Shen Yusu , Wang Dan 
Published: April 2020

Purpose
As an important part of the rotor system, the damping coefficient of ball bearing has a great influence on the dynamic characteristics of the system. This study aims to propose a theoretical calculation method and an experimental test method to obtain the damping coefficient of ball bearing.

Design/methodology/approach
Based on Hertzian contact theory and elastohydrodynamic lubrication theory, the point contact oil film damping analysis model of ball bearing is established. The comprehensive damping calculation method considering external radial load, centrifugal force, ball spin, rotational speed and lubricating oil film is derived. The multigrid method is used to obtain the oil film pressure and thickness distribution in the contact zone. The variation trend of comprehensive damping with bearing radial load, rotational speed, oil film thickness and viscosity is analyzed. The test platform is designed and the influencing factors of damping are tested.

Findings
The validity of the model and reliability of the test device are verified by comparing the good consistency obtained in the work. The results show that the comprehensive damping of ball bearing increases with the increase of radial load and decreases with the increase of rotational speed.

Originality/value
At present, the existing bearing damping model can achieve approximate calculation of damping, but the factors considered in these models are not comprehensive enough. Besides, few studies exist regarding test platform of bearing damping, and a perfect test plan has not yet been formed. In this paper, the comprehensive damping calculation model of ball bearing is improved, and a complete experimental scheme is proposed to provide reference for the comprehensive damping theory and experimental research of bearing.

The influence of IFRS mandatory adoption on value relevance of intangible assets in Italy
Authors: Cordazzo Michela , Rossi Paola 
Published: April 2020

PurposeFollowing the mandatory IFRS adoption in 2005, the Continental European accounting systems changed. This study investigates if it influenced the value relevance of intangible assets in Italy.Design/methodology/approachTo measure the value relevance of intangible assets of non-financial firms listed on Borsa Italiana from 2000 to 2015, this study isolates the impact of several classes of intangible assets on stock prices and then classifies firms according to intangible asset intensity.FindingsGoodwill, intellectual property and other rights, start-up costs or other intangible assets are significantly correlated with stock prices when Italian accounting standards were applied prior to 2005, whereas research and development expenditures are not associated with stock prices. The mandatory IFRS adoption has exerted positive effects only for goodwill and research and development expenditures, and it is negative for start-up costs. Further, when intangible-intensive firms are considered in the post-IFRS adoption period, declining value relevance exists relative to intellectual property and other rights or research and development expenditures; goodwill and other intangible assets increase in value relevance.Research limitations/implicationsThis study is subject to country-specific determinants and firm-specific characteristics. It treats accounting standards as exogenous, and the classification reflects the concentration of intangible assets in an industry. By relying on investors’ assessments of risk, it does not sufficiently explore the risk conveyed by future abnormal earnings and earnings volatility.Practical implicationsThis study offers insights for measuring and reporting intangible assets, by specifying that their value relevance depends on their level and aggregation.Originality/valueThis study investigates the value relevance of intangible assets in the post-IFRS period, in reference to intangible-intensive firms. It also divides intangible assets into several classes to specify the value relevance of goodwill.

Authors: Lee Hanna , Xu Yingjiao , Li Ailin 
Published: April 2020

PurposeThe purpose of this study is to determine the influence of technology visibility and subsequent perceptions of VFRs on consumers' intention to adopt VFRs in the online shopping context. A cross-cultural comparison was conducted to examine the different relationships among technology visibility, consumer perceptions and adoption intentions between the Chinese and Korean consumers.Design/methodology/approachData were collected from 306 Chinese and 324 Korean consumers. The data were empirically analysed using structural equation modelling as well as multi-group comparisons.FindingsEmpirical results suggest significant influence of technology visibility on consumers' experiential and functional perceptions towards VFRs and accordingly on their adoption intention towards VFRs. Significant differences were also revealed between the Chinese and Korean consumers in their adoption behaviours towards VFRs.Research limitations/implicationsThe comparison was only conducted between the Chinese and Korean consumers. If two countries from two dramatically different cultures were compared, the results might be more significant.Practical implicationsAn important implication is that enhancement of visibility is crucial for technology adoption considering its importance in shaping consumers' perceptions towards the technology.Originality/valueThe paper empirically tested the importance of technology visibility in consumers' new technology adoption in the VFR context from a cross-cultural perspective.
The mapping of information and communication technologies, and knowledge management processes, with company innovation
Authors: Jarmooka Qabas , Fulford Richard Glenn , Morris Robyn , Barratt-Pugh Llandis 
Published: April 2020

Purpose
National and organizational innovation is currently at the forefront of media discussion and is viewed as critical to economic development. While the argument for investment is universal, how it should be orchestrated is uncertain. The purpose of this paper is to bring together the three major related components of information and communication technology (ICT), knowledge management processes (KMP) and innovation, to explore empirically the constituents of ICT and KMP that improve innovation within Australian enterprises.

Design/methodology/approach
The method is a quantitative survey of 148 industry managers. The data was refined through confirmatory factor analysis. The hypotheses were evaluated by regression equations and parameter estimates. The findings were identified by the magnitude of the effect sizes.

Findings
The study’s evidence illuminated how specific components of ICT and KMP impact on particular aspects of innovation. The findings indicate key emerging relationships and then propose a conceptual model validated by the analysis of the survey evidence. The study identifies that investment in ICT and KMP has a positive impact on innovation performance. A particular finding is that information or data capture technologies have the most significant positive consequence for innovation.

Practical implications
The modeling can be used by managers as a guide to mapping ICT and KMP to specific innovation outcomes. In a modified form, it could be applied as a self-assessment instrument for managers in organizations.

Originality/value
This is a valuable addition to current literature, as it is unique in bringing these three key components together, confirming their instrumental impact, and indicating the differentiated investment strategies that can be implemented to achieve specific and unique innovation agendas. In addition, some refined constructs, which were developed as part of this study, provide a pre-tested, validated survey instrument for further research.
Understanding the individual's reactions to the organizational change: a multidimensional approach
Authors: Borges Renata , Quintas Camila Amaro 
Published: April 2020

PurposeThe objective of this research is to analyze in a multidimensional perspective the individual responses to organizational change, specifically about the implementation of a new performance evaluation system, investigating some antecedents of the individual reactions to change.Design/methodology/approachCompanies from the education industry were surveyed, and standardized questionnaires were applied. We obtained a sample size of 386 valid responses. The structural equation modeling (SEM) was employed to assess the measurement model and test the hypotheses.FindingsThe results indicate positive reactions to the organizational change, without ambivalent responses. Employees' cognitive and behavioral reactions are influenced by the individuals' anticipation and past similar organizational change and do not depend on the perceived threat to social work life. The influence of group pressure and organizational readiness on cognitive and behavioral reactions differs in the direction that group pressure affects behaviors but not thoughts, and organizational readiness affects thoughts but not behaviors.Research limitations/implicationsLimitations include the inadequate measures of individuals' emotional reaction, preventing this dimension from being tested.Originality/valueThis research provides theoretical contributions as the literature on organizational change lacks a multidimensional view on individuals' reactions to change. The main contribution of this study is to investigate how each of the individual and organizational antecedents of the employees' responses to the change influences the cognitive and behavioral reactions towards the change employing a multidimensional approach.

Authors: Hough Christie , Sumlin Cameron , Green Kenneth Wilburn 
Published: April 2020

PurposeThe purpose of this paper is to empirically assess the combined impact of the ethical environment, organizational trust and workplace optimism on individual performance.Design/methodology/approachA structural model is theorized and data from 250 individuals working for private organizations were analyzed using partial-least-squares structural equation modeling.FindingsBoth the ethical environment and organizational trust positively impact workplace optimism. Of the ethical environment, organizational trust and workplace optimism, only workplace optimism directly impacts individual performance. The impact of the ethical environment and organizational trust on individual performance is indirect through workplace optimism.Research limitations/implicationsTo the authors’ knowledge, this is the first empirical study to assess the combined impact of the ethical environment, organizational trust and workplace optimism on individual performance. It is important to conduct similar studies to verify these findings.Practical implicationsAn ethical environment and organizational trust foster high levels of workplace optimism that in turn lead to improved employee performance.Originality/valueThe important role that workplace optimism plays within the ethical climate of organizations is theorized and assessed. This is the first empirical assessment of the mediational role of workplace optimism on the established relationships between ethical environment and individual performance, and organizational trust and individual performance.

AbstractThis account presents information on all aspects of the biology ofQuercus rubraL. (Red Oak, Northern Red Oak; syn.Q. borealis,Q. maxima) that are relevant to understanding its ecological characteristics and behaviour. The main topics are presented within the standard framework of theBiological Flora of the British Isles:distribution; habitat; communities; responses to biotic factors; responses to environment; structure and physiology; phenology; floral and seed characters; herbivores and disease; history; and conservation.Quercus rubrais a large deciduous tree native to eastern North America. In its native range this species is one of the most important mid‐successional tree species. Since the 18th centuryQ. rubrahas been introduced into forest management in Europe and elsewhere. Currently,Q. rubrais a naturalized species in 23 countries. It is an important source of wood, and this was one of the most important reasons for its introduction in forests. In forest management this species is valued for its high growth rate and drought resistance. Red Oak is also widely cultivated in Europe for its ornamental value—red leaves in autumn and smooth, grey bark.Red Oak is a threat to native species within its introduced range as it can alter environmental conditions beneath its canopy, especially by decreasing light availability and litter decomposition rate. Such conditions also contribute to biotic homogenization of the understorey vegetation.Q. rubrais widely dispersed by small mammals and birds, up to 1,500 m from seed sources, thereby increasing its potential invasiveness.In EuropeQ. rubraseems to be less prone to herbivores and fungi, in contrast to its native range, where it is grazed by ungulates and insects, and infected byPhytophthoraand oak wilt. Due to its higher tolerance to drought than native European oaks,Q. rubrais claimed to be one of the species replacing native trees which are decreasing due to climate warming. However, consideration of all possible consequences is needed in wide‐scale introduction of alien species, such asQ. rubra, due to negative impacts on native ecosystems.

AbstractPersonalized medicine, the treatment best suited for an individual, is a hot field of clinical research in the world. Many recent studies have shown that genetic variations have a great influence on the treatment. This study aimed to identify the distribution differences of very important pharmacogene (VIP) variants between the Tibetan population and the other 26 populations from the 1000 Genomes project. Based on the PharmGKB database, we successfully genotyped 50 VIP variants located in 27 genes in the Tibetan population. We also compared the genotype frequencies of VIP variants between Tibetan population and the other 26 populations. Without adjustment, the Chi‐square test showed that the only significant variant between Tibetans and every other group was rs1801159 in dihydropyrimidine dehydrogenase (DPYD), followed by rs1800566 in NAD(P)H quinone dehydrogenase 1 (NQO1) and rs1051296 in solute carrier family 19 member 1 (SLC19A1). After Bonferroni's multiple adjustments, the genotype frequencies distribution of DPYD rs1801159 was found to be different in Tibetans compared to the other 26 groups, apart from ACB and ASW. Moreover, genetic structure/F‐statistics (Fst) analysis and the phylogenetic tree illustrated that Tibetans had a closer affinity with CDX, CHB, CHS, JPT and KHV. Our data will complement pharmacogenomics information of the Tibetan population and provide theoretical support for the realization of individualized medical treatment for Tibetans in the future.

Published: April 2020

AbstractThe objective of this study was to assess knowledge and attitudes of nutrition and dietetic college students regarding food science and technology. It was designed as a cross‐sectional survey using a self‐administered online questionnaire, constructed by a formative research process, including accredited dietetics programs in the United States and Puerto Rico. There were a total of 535 participants consisting of adult (≥18 years old) nutrition and dietetic students (undergraduate, graduate, and dietetic interns). Frequencies and percentages were calculated to describe the study participants. Where appropriate, the Chi‐square test was used to test categorical variables across two or more levels. More than half (55.1%) agreed that they were knowledgeable in food science and technology. Greater than half (56.8%) of the participants indicated that they “occasionally” or “rarely” covered food science and technology topics in their current program and 70.1% either “agreed” or “strongly agreed” that their current curriculum could benefit from adding more related topics. Overall, the majority (66.7%) of respondents indicated their overall impression of the food industry was “poor” or “neutral.” The results support adding/strengthening food science and technology components in nutrition curricula. Such education may provide future nutrition professionals with the knowledge and skills needed to effectively utilize food science and technology within their field.
Effect of aquaporin 1 on mouse peritoneal mesothelial cells after a long‐term peritoneal dialysis

Published: April 2020

AbstractAquaporin 1 (AQP1) is one member of the aquaporin family, also the deeply studied one. It is widely located on the endothelial cells, but the effect of AQP1 on the peritoneal mesothelial cells (PMCs) after long‐term peritoneal dialysis (PD) has not been reported before. We divided normal mice into two groups, control group and dialysis group, to confirm the fibrotic changes and expression of APQ1 on peritoneal mesothelial cells. Then we assigned normal mice and AQP1 knockout mice into four groups: Control group, normal dialysis group, AQP1 knockout control group and AQP1 knockout dialysis group. The two dialysis groups received 4.25% glucose dialysis for 28 days. We found that mice in both dialysis groups showed peritoneal fibrotic changes, which were most severe in the AQP1 knockout dialysis group; the peritoneal thickness in the AQP1 knockout dialysis group was also thicker than that in the dialysis group (P < .05). We used electron microscopy to detect ultrastructural changes and observed changes in microvilli and vacuolar degeneration in mesothelial cells from all groups except the control group. The basement membranes were damaged in the AQP1 knockout dialysis group, and peritoneal mesothelial cells were disrupted and detached in this group. Together our findings indicate that AQP1 plays an important role in maintaining the physiological functions of peritoneal mesothelial cells, and AQP1 can protect mesothelial cells during dialysis.
