AbstractDNA barcode databases are increasingly available for a range of organisms facilitating the wide application of DNA barcode-based pursuits. Here we announce the development of a comprehensive DNA barcode database of the Japanese woody flora representing 43 orders, 99 families, 303 genera and 834 species and comprising 77.3% of genera and 72.2% of species of woody plants in Japan. A total of 6,216 plant specimens were collected from 223 sites (municipalities, i.e. city, town, village) across the subtropical, temperate, boreal and alpine biomes in Japan with most species represented by multiple accessions. This database utilised three chloroplast DNA regions (rbcL, trnH-psbA and matK) and consists of 14,404 barcode sequences. Individual regions varied in their identification rates with species-level and genus-level rates for rbcL, trnH-psbA and matK being 57.4%/ 96.2%, 78.5%/ 99.1 % and 67.8%/ 98%, respectively. Identification rates were higher using region combinations with total species level rates for two region combinations (rbcL & trnH, rbcL & matK, and trnH-psbA & matK) ranging between 90.6–95.8%, and for all three regions equal to 98.6%. Genus level identification rates were even higher ranging between 99.7–100% for two region combinations and being 100% for the three regions. These results indicate that this DNA barcode database is an effective resource for investigations of woody plants in Japan using DNA barcodes and provides a useful template for development of libraries for other components of the Japanese flora.

AbstractCyclic guanosine monophosphate (cGMP) signalling plays a fundamental role in many cell types including platelets. cGMP has been implicated in platelet formation, but mechanistic detail about its spatiotemporal regulation in megakaryocytes (MKs) is lacking. We expressed a photo-activated guanylyl cyclase, Blastocladiella emersonii Cyclase opsin (BeCyclop), after viral-mediated gene transfer in bone marrow (BM)-derived MKs to precisely light-modulate cGMP levels. BeCyclop-MKs showed a significantly increased cGMP concentration after illumination, which was strongly dependent on phosphodiesterase (PDE) 5 activity. This finding was corroborated by real-time imaging of cGMP signals which revealed that pharmacological PDE5 inhibition also potentiated nitric oxide (NO) triggered cGMP generation in BM MKs. In summary, we established for the first time optogenetics in primary MKs and identified PDE5 as the predominant PDE regulating cGMP levels in MKs. These findings also demonstrate that optogenetics allows for the precise manipulation of MK biology.

Published: November 2021

PurposeThe paper is devoted to presenting a systematic investigation on the mechanical model and nonlinear dynamic characteristics of spur gear system with and without input shaft crack.Design/methodology/approachConsidering the backlash, load-distribution, time-varying meshing stiffness and sliding friction, the modelling of a 5DOF gear system is proposed. Likewise, stiffness and damping models under elastohydrodynamic lubrication are developed, and sliding friction between gear pair is also outlined. In particular, a cracked input shaft which affects the support stiffness is presented, and breathing crack in keyway is adopted. On this basis, the dynamic responses of a gear system with and without input shaft crack are examined using numerical method, and some classical response diagrams are given, illustrating the effect of the important parameters on the gear system.FindingsDynamic simulation demonstrates that there exist periodic, quasi-periodic and chaotic motions in the gear system, and rational speed of the gear pair has noteworthy effects on vibration characteristic. Besides, comparison between healthy and cracked condition of input shaft indicates that occurring of crack convert periodic motion to quasi-periodic or chaotic motion.Originality/valueThe results give an understanding of the operating conditions under which undesirable dynamic behavior occurs, and provide some useful information to design and diagnose such gear system with crack fault.
The definition of entrepreneurship: is it less complex than we think?
Authors: Prince Sam , Chapman Stephen , Cassey Peter 
Published: November 2021

PurposeThe paper introduces a new conceptualisation of entrepreneurship that promotes a broader perspective of the phenomenon. The purpose of the paper is to re-conceptualise the act of entrepreneurship so as to reduce it to the fundamental behaviours and processes.Design/methodology/approachThe paper sets out the motivations for and challenges in establishing a broader definition of entrepreneurship. Following this, current approaches to defining entrepreneurship are reviewed. In light of these, a definition of entrepreneurship is offered that captures a new perspective in understanding entrepreneurship. A critique of the offered definition is offered with regards to promoting theory development, empirical research, quality predictions and a distinctive research domain.FindingsThe authors argue that a definition of entrepreneurship that is focussed on the development and validation of ideas provides a thought-provoking re-conceptualisation of entrepreneurship. Extant perspectives on entrepreneurship as business/organisation creation, uncertainty, innovation, value creation and opportunity recognition/creation are drawn on to demonstrate the applicability of the definition.Originality/valueThe pursuit for an encompassing definition of entrepreneurship has been both extensive and earnest, which has inadvertently resulted in a sizable pool of definitions. The authors offer a re-conceptualisation of entrepreneurship with the intent to provide a broad yet coherent definition that encompasses all acts of entrepreneurship. A benefit of this conceptualisation is the establishment of the endpoint of the entrepreneurship process that delineates it from the domain of management.

PurposeThe COVID-19 pandemic had brought drastic economic, social and technological changes in society. The drastic changes and uncertainty in the environment had forced various industries to evolve effectively to cope with the unexpected change and subsequently bounce back to regain business success. For instance, private higher learning institutions face steep challenges due to the shortfall of organisational capabilities. The study aims to examine the role of leadership capabilities and organisational resilience in regaining organisational success among higher private learning institutions in Malaysia.Design/methodology/approachAccording to the dynamic capabilities theory, organisational resilience and leadership capabilities are among the highest order of indicators for organisational success. Subsequently, this study examines the mediating role of leadership capabilities on the relationship between organisational resilience on organisational performance. The dynamic capabilities-based framework was tested using the structural equation modelling technique with the use of partial least squares approach. Data were analysed using 120 responses.FindingsBased on the 120-questionnaire survey received, this study found that organisational resilience and leadership capabilities contribute significantly to the performance of private higher learning institutions. In addition, this study found strong support for the mediating role of leadership capabilities to promote performance. The findings have both theoretical and practical implications for post-disaster organisation resilience development.Research limitations/implicationsThe work focuses on values that would have an impact towards organisational performance, which is an important factor of survival in an unpredictable environment. The findings are limited by the indicated constraints used in this study.Practical implicationsOrganisational survival techniques would provide managers, owners and leaders effective techniques that can be implemented to extend and improve the organisation's life cycle. The focus on organisational resilience and leadership factors would greatly improve the overall sustainability and performance of the organisation.Originality/valueThe study contributed by showing the importance, use and interaction needed from organisational resilience and leadership capabilities for them to survive when there is a sudden change in the environment. The timing and uniqueness of the data during the pandemic illustrates how organisations can survive with high levels of weightage towards resilience and leadership. This research is different from other studies as it had examined the impact of values and resilience and leadership in organisations.
Identifying the development stages of virtual teams – An application of social network analysis
Authors: Lin Chun-Nan , Roan Jinsheng 
Published: November 2021

PurposeThe purpose of this study is to explore some quantitative indicators from the social network analysis, observe the variations of these indicators over time and determine whether these indicators fit into the traditional team development stages model or theory. The primary focus is on the perspective of social interaction rather than the suitability of the indicator, i.e. the authors will not determine the optimal indicators nor compare the performance of different indicators. This study aims to propose a quantitative method to identify the development stages of virtual teams.Design/methodology/approachTwo phases were designed in this study. The first phase was a simple study to prove the preliminary ideas and explore which quantitative indicators would be suitable for analysis. In total, 16 undergraduates were randomly assigned to two virtual teams. They were required to complete an information system (IS) project through virtual teamwork and use information and communications technologies (ICTs) to communicate with each other. After proving the preliminary ideas, the authors collected communication data of the 30 virtual teams working on IS projects in the second phase. The total duration of this process was two months.FindingsThe findings practically identified three stages, which were found to be consistent with that of the previous qualitative studies. In the initial (inclusion) stage, intensity had an upward trend. In the second (control) stage, centralization had an upward trend. In the final (affection) stage, intensity and density had upward trends and centralization had a downward trend. Both density and centralization also became smooth in this final stage. The conclusion can serve as a basis for further studies in virtual team development.Originality/valueA successful virtual team will help industries to reduce their costs and increase performance and benefits. The findings will help industries quickly and objectively identify which stage they are at. This quantified approach will provide managers and leaders with a simple, useful way to highlight the needs for managing different aspects of team behavior at each stage of development. After establishing this approach, managers and leaders will be able to make plans to improve existing processes, set priorities, provide suitable principles and guidelines, etc., and eventually improve virtual team performance.

Published: November 2021

Purpose
The Purpose of this paper is to identify statistical relationships between visual environment and occupant productivity. Visual environment is one of the most important indoor environmental quality (IEQ) parameters, and it directly impacts occupant productivity in offices. The literature outlines the significance of the impact. Still, there is a lack of investigation, statistical analysis and inter-relationships between the independent variables (IEQ factors), especially in the hot and arid climate.

Design/methodology/approach
This study presents a research study investigating the effects and shows statistical relationships between IEQ on occupant comfort and productivity. The study was conducted in the Middle East, and data was collected for 12 months. It used the response surface analysis to perform analysis.

Findings
This study outlined seven unique relationships highlighting the recommended range, inter-dependencies. Results include that illumination has maximum effect on visual comfort and temperature, daylight having direct influence and relative humidity, wall type next to the seat and kind of workspace also impact visual comfort and productivity. These findings would help to improve occupant comfort and productivity in office buildings. It is recommended to include results and recommendations on design guidelines for office buildings.

Originality/value
This study presents the unique effects of non-visual IEQ parameters on visual comfort and productivity. This investigation also provides a unique method to develop the statistical relationship between various indoor environmental factors and productivity in different contexts and buildings.
Corporate boards' and firms' R&D responses to performance feedback
Authors: Jirásek Michal 
Published: November 2021

PurposeA firm will respond to performance feedback, i.e. a comparison of its current performance with the goals to which it aspires, by means of changes in its search activity. There is an emerging body of literature that studies how such behavioral responses are shaped by important decision-makers inside firms. The study focuses on the corporate board – one of the most influential decision-making groups in terms of strategy. More specifically, the study aims to study the moderation effect of the size, turnover and age diversity of the board.Design/methodology/approachThe sample is based on the largest listed German automobile and manufacturing firms followed between the years 2001 and 2015. The sample is analyzed using fixed-effects panel data models.FindingsThe findings indicate that the age diversity of the corporate board and, partially, also the turnover of its members moderate firms' responsiveness to performance feedback. On the other hand, the size of the board does not seem to play a role. The study, therefore, supports the notion of taking into account the characteristics of the corporate board when analyzing strategic decision-making and points to areas for further research.Originality/valueThe study contributes to the literature by empirically testing the moderating effect of three characteristics of corporate boards that have not been largely tested in the literature to date.

Published: November 2021

Purpose
The purpose of this study is to examine the dimensions of organizational learning (OL), entrepreneurial orientation (EO), personal value toward the firm performance of small and medium enterprises (SMEs) in North Sumatera, Indonesia.

Design/methodology/approach
This study used a quantitative methodology using Smart partial least squares of the structural equation model. A survey is done by distributing the questionnaires to the respondents (owner-managers) of SMEs across sectors. Using a convenient sampling technique, 128 respondents are selected. Using a cross-sectional survey design, 11 hypotheses are tested.

Findings
It is found that the innovativeness of EO and personal value both have a significant relationship with firm growth. While OL is significantly related to the innovativeness of EO, risk-taking of EO and proactiveness of EO. Then, both innovativeness of EO and proactiveness of EO significantly mediate the relationship of OL and firm growth. However, OL, proactiveness of EO and risk-taking of EO are insignificantly related to firm growth, while risk-taking of EO also insignificantly mediates the relationship of OL and firm growth.

Originality/value
EO (innovativeness, risk-taking and proactiveness) is deemed a crucial factor in running businesses by SMEs, while OL and personal value play a significant role in creating a competitive advantage that is needed for growth.
Transformational leadership and work performance in health care: the mediating role of job satisfaction
Authors: Curado Carla , Santos Rúben 
Published: November 2021

Purpose
The purpose of this study is to investigate the relation among transformational leadership, job satisfaction and adaptive performance of health-care professionals and administrative personnel of Portuguese non-profit health-care organizations.

Design/methodology/approach
This study collects data using an online survey sent to a nationwide database. This study uses a structural equation modeling approach to specify and estimate models of linear relations among the variables. This study tests the direct and mediated effects proposed by the hypotheses using a sample of non-profit 192 health-care organizations.

Findings
The results show (regardless of being direct health-care professionals or employees performing support functions) that job satisfaction fully mediates the relation between transformational leadership and adaptive performance. Transformational leadership alone and directly seems to have no effect on adaptive performance.

Research limitations/implications
The theoretical implications of this study concern the influence that transformational leadership has on job satisfaction and the consequent indirect influence on performance regardless of being direct health-care professionals or employees performing support functions.

Practical implications
The main managerial contribution of the study regards how health-care organizations’ leaders may contribute to increase employees’ performance by ensuring job satisfaction.

Originality/value
Despite the numerous studies that relate transformational leadership to job satisfaction and performance, there is a gap on research run in health care settings involving both health care and administrative personnel. Transformational leadership can increase the satisfaction of health-care professional and consequently job satisfaction has a positive influence on employees’ adaptive performance.

Thymoquinone attenuates isoproterenol‐induced myocardial infarction by inhibiting cytochrome C and matrix metalloproteinase‐9 expression
Authors: Medhet Marwa , El‐Bakly Wesam M. , Badr Amira M. , Awad Azza , El‐Demerdash Ebtehal 
Published: November 2021

AbstractThymoquinone (TQ) is the main active constituent of Nigella sativa. The present study aimed to investigate the effect of TQ on apoptotic parameters and MMP‐9 expression in isoproterenol (ISP)‐induced myocardial infarction (MI). TQ was given once daily for 7 days at doses of 10 and 20 mg/kg orally with ISP (86 mg/kg; s.c.) administered on the sixth and seventh days. TQ pre‐treatment protected against ISP‐induced MI as approved by normalisation of electrocardiogram (ECG) and b (CK)‐MB, minimal histopathological changes, and reduction of the infarction size. Effects of TQ could be supported by its antioxidant activity, evidenced by the increase of cardiac reduced glutathione and total serum antioxidant capacity, and the inhibition of ISO‐induced lipid peroxidation. TQ anti‐inflammatory activity was associated with reduced expression of NF‐κB and TNF‐α. TQ ameliorated cardiomyocytes, apoptotic pathways by inhibiting both the intrinsic pathway, via reducing cytoplasmic cytochrome C, and the extrinsic pathway, by inhibiting TNF‐α and caspases, and the effect of TQ was dose‐dependent. Moreover, TQ reduced the expression of metalloproteinase (MMP)‐9, which is considered as a prognostic marker of ventricular remodelling, recommending that TQ can be used as a possible supplement to minimise post‐MI changes. So, we conclude that TQ antiapoptotic activity and the inhibitory modulation of MMP‐9 expression contribute to TQ protective effects in MI. To our knowledge, this is the first study reporting the effect of TQ on cytochrome c activity and MMP‐9 expression in MI.
