The relationship between individual entrepreneurial orientation (IEO) and entrepreneurial bricolage: exploring passion and perseverance
Authors: Mohammadi Saeed 
Published: June 2021

Purpose
The purpose of this paper is to investigate the relationship between individual entrepreneurial orientation (IEO) and bricolage behavior, considering the two emerging dimensions of IEO measurement: passion and perseverance.

Design/methodology/approach
A total of 187 postgraduate students who have recently started a new business were selected as the research sample. This study aimed to explore the multidimensional perspective of the new IEO construct. Hierarchical multiple regression analysis was applied to examine the hypotheses.

Findings
The results show that along with the enactment of traditional dimensions of IEO, examining the newly introduced dimensions illustrates a distinguished explanation of IEO in resource-scarce environments and leads to a development in entrepreneurial bricolage.

Originality/value
This study examined the IEO construct with two emerging dimensions of IEO measurement: passion and perseverance. This IEO construct is primarily associated with individual behavior and declares bricolage behavior more effectively.
Energy efficiency financing and the role of green bond: policies for post-Covid period
Authors: Anh Tu Chuc , Rasoulinezhad Ehsan 
Published: June 2021

PurposeOne of the major negative effects of the Coronavirus outbreak worldwide has been reduced investment in green energy projects and energy efficiency. The main purpose of this paper is to study the role of green bond proposed by the World Bank in 2008, as a reliable instrument to enhance the capital flow in energy efficiency financing and to develop green energy resources during and post the current challenging global time.Design/methodology/approachWe model energy efficiency for 37 members of OECD through a panel data framework and quarterly data over 2007Q1–2020Q4.FindingsThe major results reveal the positive impacts of issued green bonds and regulatory quality index on energy efficiency, while any increase in inflation rate and urbanization decelerates the progress of raising energy efficiency.Practical implicationsAs highlighted concluding remarks and policy implications, it can be expressed that the tool of green bond is a potential policy to drive-up energy efficiency financing and enhancing environmental quality during and post-COVID period. It is recommended to follow green bond policy with an efficient regulation framework and urbanization saving energy planning.Originality/valueTo the best of the authors' knowledge, although a few scholars have investigated the impacts of COVID-19 on green financing or examined the energy efficiency financing, the matter of modeling energy efficiency–green bond relationship has not been addressed by any academic study. The contributions of this paper to the existing literature are: (1) it is the first academic study to discover the relationship between energy efficiency and green bond in OECD countries, (2) since our empirical part provides estimation results based on quarterly data covering the year of 2019 and 2020, it may offer some new policy implications to enhance energy efficiency financing in and post-COVID period, (3) furthermore, we consider energy efficiency indicator (mix of industrial, residential, services and transport energy efficiency) as the dependent variable instead of using the simple energy intensity variable as a proxy for energy efficiency.

Authors: Roșca Natalia C. , Roșca Alin V. , Pop Ioan 
Published: June 2021

Purpose
The purpose of this paper is to numerically study the problem of mixed convection flow of a hybrid nanofluid past a vertical wedge with thermal radiation effect.

Design/methodology/approach
The governing nonlinear partial differential equations are transformed into a system of ordinary differential equations by a similarity transformation, which is then solved numerically through the function bvp4c from MATLAB for different values of the governing parameters. The solutions contain a mixed convection parameter λ that has a considerable impact on the flow fields.

Findings
It is found that the solutions of the ordinary (similarity) differential equations have two branches, upper and lower branch solutions, in a certain range of the mixed convection and several other parameters. To establish which of these solutions are stable and which are not, a stability analysis has been performed. The effects of the governing parameters on the fluid flow and heat transfer characteristics are illustrated in tables and figures. It is found that dual (upper and lower branch) solutions exist for both the cases of assisting and opposing flow situations. A stability analysis has also been conducted to determine the physical meaning and stability of the dual solutions.

Practical implications
This theoretical study is significantly relevant to the applications of the heat exchangers placed in a low-velocity environment and electronic devices cooled by fans.

Originality/value
The case of mixed convection flow of a hybrid nanofluid past a vertical wedge with thermal radiation effects has not been studied before, and hence all generated numerical results are claimed to be original and novel.

Authors: Folgado-Fernández José A. , Duarte Paulo , Hernández-Mogollón José Manuel 
Published: June 2021

PurposeThe purpose of this study is to investigate and compare the role of communication, structural and intangible elements on both tourists’ rational and emotional engagement across five different types of events (nature, gastronomy, religion, theatre and music).Design/methodology/approachResponses from 1,528 tourists were obtained through a face to face questionnaire in five heterogeneous events in the Spanish region of Extremadura, a well-known cultural tourism destination. Linear regressions were used to evaluate focal constructs’ contribution (emotional and rational engagement, formal and informal communication and structural and non-structural elements) on tourists’ engagement across events.FindingsThe results revealed that tourist’s rational and emotional engagement depends on the type of event. Non-structural elements seem to be important for rational and emotional engagement for gastronomic and cultural events. Besides the impact of structural elements on rational engagement, all other factors seem to have a mixed influence. Therefore, practitioners must select the factors to highlight according to the type of events, besides structural factors.Practical implicationsThe current results allow tourism managers to understand the mechanisms for tourists’ engagement in a multi-event scenario to strategically select and use and communicate each type of appeal when planning and communicating events to specific target audiences.Originality/valueUnlike most studies that focus on a single event or typology, this study combines a set of heterogeneous events to provide a complete picture of tourism engagement for the tourism sector.

Leadership development facilitated by the “sandwich” and related glaucoma fellowship programs
Authors: Liu Victoria , Whitford Rita , Damji Karim F. 
Published: June 2021

Purpose
The purpose of this paper is to evaluate leadership training in the Sandwich Glaucoma Fellowship (SGF), a program in which fellows learn skills in a developed world institution and their home country to become leaders in glaucoma care.

Design/methodology/approach
This paper is a retrospective, qualitative and quantitative evaluation. Participants of the SGF between 2007 and 2019 were provided a survey eliciting demographic information, leadership training exposure, development of leadership competencies and feedback for the fellowship program.

Findings
Seven of nine alumni responded. The fellowship strongly impacted leadership competencies including integrity (8.8, 95% CI 7.8–9.8), work ethic (8.64, 95% CI 7.7–9.6) and empathy (8.6, 95% CI 7.7–9.5). A total of 85% of alumni indicated positive changes in their professional status and described an increasing role in mentorship of colleagues or residents as a result of new skills. Lack of formal leadership training was noted by three respondents. Informal mentorship equipped fellows practicing in regions of Sub Saharan Africa with competencies to rise in their own leadership and mentoring roles related to enhancing glaucoma management. Suggested higher-order learning objectives and a formal curriculum can be included to optimize leadership training catered to the individual fellow experience.

Originality/value
Leadership is necessary in health care and specifically in the context of low- and middle-income countries to bring about sustainable developments. The SGF contains a unique “Sandwich” design, focusing on the acquisition of medical and leadership skills. This evaluation outlines successes and challenges of this, and similar fellowship programs. Other programs can use a similar model to promote the development of skills in partnership with the fellows’ home country to strengthen health-care leaders.
How do bank-affiliated venture capitalists do deals? Towards a model of multiple investment logics
Authors: Granz Christian 
Published: June 2021

PurposeThis paper aims to investigate German bank-affiliated venture capitalists’ investment practices and the emergence of their investment logics. Most studies focus on the investment behaviour of independent venture capitalists and little is known about dependent venture capitalists’ investment behaviour. The present study contributes to filling this gap in entrepreneurial finance literature.Design/methodology/approachThe paper uses an exploratory qualitative research approach based on 27 semi-structured interviews with the top management of German bank-affiliated venture capitalists and industry experts to develop a conceptual model that explains the investment logics of bank-affiliated venture capitalists. A large amount of archival data has also been collected and used for the analysis.FindingsThe results indicate that bank-affiliated venture capitalists either follow an autonomous, contingent or hybrid investment logic. A bank-affiliated venture capitalist’s isomorphic focus – whether they feel isomorphic to the external venture capital environment or the internal parent bank’s environment – explains the emergence of multiple investment logics.Practical implicationsThe paper encourages banks to get a better understanding of how the venture capital industry works and what they need to do to compete again independent venture capitalists. Banks and their affiliated venture capital units can improve their deal flows by recognising that they need to get accepted as an on-par investor in the venture capital environment.Originality/valueThe current study is the first of its kind investigating multiple investment logics by focussing on the link between different isomorphic habits and the specific context of bank-affiliated venture capitalists.
Igniting a conversation: Indigenous intercultural doctoral supervision
Authors: Cavanagh Vanessa , Hammersley Laura , Adams Michael 
Published: June 2021

AbstractThe importance of higher degree research supervision is well studied and understood. There is also an increasing body of literature examining cross‐cultural and intercultural supervision. Much less research, however, focuses on supervision experiences with Indigenous postgraduate students and their non‐Indigenous supervisors. High‐quality, culturally appropriate, and safe supervision is even more significant for Indigenous postgraduate students, who also have to deal with the ongoing inequities of colonialism in both higher education and broader society. The doctoral research at the centre of this article is undertaken by an Indigenous person who is supervised by two non‐Indigenous settler academics in geography. Drawing on Indigenous and non‐Indigenous scholarly research, we provide narrative examples of some of the complexities and possibilities experienced through the research process and supervisory relationship. The article does not present an argument for a best practice model in intercultural supervision, nor does it make recommendations or argue for standardised practices in geography. Instead, we seek to contribute to emerging discussions on Indigenous doctoral supervision in settler colonial contexts and, in doing so, highlight spaces of resistance as we challenge conventional supervisory relationships and knowledge making practices.
The role of the Listeria monocytogenes surfactome in biofilm formation
Authors: Janež Nika , Škrlj Blaž , Sterniša Meta , Klančnik Anja , Sabotič Jerica 
Published: June 2021

SummaryListeria monocytogenes is a highly pathogenic foodborne bacterium that is ubiquitous in the natural environment and capable of forming persistent biofilms in food processing environments. This species has a rich repertoire of surface structures that enable it to survive, adapt and persist in various environments and promote biofilm formation. We review current understanding and advances on how L. monocytogenes organizes its surface for biofilm formation on surfaces associated with food processing settings, because they may be an important target for development of novel antibiofilm compounds. A synthesis of the current knowledge on the role of Listeria surfactome, comprising peptidoglycan, teichoic acids and cell wall proteins, during biofilm formation on abiotic surfaces is provided. We consider indications gained from genome‐wide studies and discuss surfactome structures with established mechanistic aspects in biofilm formation. Additionally, we look at the analogies to the species L. innocua, which is closely related to L. monocytogenes and often used as its model (surrogate) organism.

AbstractAimsTo investigate whether reduction in opioid use differs when treated by either buprenorphine–naloxone (BUP) or methadone (MET) among adults with comorbid opioid use disorder (OUD) and mental disorders.Design, Setting and ParticipantsIn a randomized controlled trial, adults with OUD were randomized to 24 weeks of either BUP or MET treatment and were followed up in 3‐yearly assessments. The present secondary analyses were based on 597 participants who completed all assessments.MeasurementsThe outcome measure was the number of days of using opioids per month during the follow‐up period. The Mini‐International Neuropsychiatric Interview (MINI) was used to classify participants into three groups: life‐time mood disorder (n = 302), life‐time mental disorder other than mood disorder (n = 114) and no mental disorder (n = 181). Medication treatment (BUP, MET, no treatment) during the follow‐up period was a time‐varying predictor.FindingsBased on zero‐inflated Poisson (ZIP) mixed regression analysis, it was found that relative to no treatment, opioid use during the follow‐up was significantly reduced by BUP [odds ratio (OR) = 0.12, 95% confidence interval (CI) = 0.07–0.21 for any use; risk ratio (RR) = 0.77, 95% CI =0.66–0.89 for days of use] and by MET [OR = 0.33, 95% CI = 0.25–0.45 for any use; RR = 0.78, 95% CI = 0.72–0.84 for days of use]. Relative to MET, BUP was associated with a lower likelihood of any opioid use among participants with mood disorders (OR = 0.52, 95% CI = 0.36–0.74) and for participants without mental disorder (OR = 0.37, 95% CI = 0.21–0.66) and fewer number of days using opioids (RR = 0.37, 95% CI = 0.25–0.56) among participants with other mental disorders.ConclusionsAmong adults with comorbid opioid use disorder and mental disorders, treatment with buprenorphine–naloxone produced greater reductions in opioid use than treatment with methadone.

AbstractDiet determination of endangered species is an essential element in defining successful conservation strategies and optimising captive breeding programmes. In this study, we developed a new diet identification system, derived from standard faecal analysis, to determine the diet of an elusive and endangered herbivore, the pygmy hippopotamus (Choeropsis liberiensis). We collected faecal samples from 10 free‐ranging individuals covering a combined home range area of about 50 km2 in Taï National Park, Côte d’Ivoire. In subsequent laboratory analyses, we extracted a large number of leaf epidermis fragments from spatially separated faecal samples and compared them with a reference plant database. Using Multiple Correspondence Analysis (MCA) of epidermis fragments combined with direct visual inspection, we identified the most frequently consumed plant species, which revealed that pygmy hippopotami qualified as intermediate feeders. Their diet was based on at least seven species of monocotyledonae, dicotyledonae and fern groups, with a preference for a small number of other plant species. We evaluate the merit of our method and discuss our findings for developing effective conservation and captive breeding strategies in an endangered species with a wild population of less than 2500 adult individuals.
Two methods of evaluating mandibular trabecular pattern in intraoral radiographs and the association to fragility fractures during a 47‐year follow up

Published: June 2021

AbstractIn this longitudinal cohort study, we explored the association of fragility fractures to sparse trabecular bone pattern in intraoral radiographs using two methods, a visual and a semi‐automated. Our aim was to study both sexes and to include younger age‐groups, during a follow‐up time of 47 years. The cohort consisted of 837 men and women aged 18–65 years, with intraoral radiographs from 1970–1971. The trabecular pattern was assessed in the mandibular premolar region with a visual and a semi‐automated method. Data on fragility fractures were acquired from the Swedish National Patient Register for 47 years of follow‐up time. Sparse trabecular pattern was found in 2.2% of the cohort using the visual method, and 18% were deemed at ‘risk of osteoporosis’ using the semi‐automated method. A total of 132 individuals suffered at least one fragility fracture during the follow‐up period. We found no significant association between fractures and sparse trabecular pattern using either method. This study shows that visual assessment, as a predictor of future fractures, may not be a suitable method for individuals of all ages and sexes. As for the semi‐automated method, there is still very limited evidence for its fracture predictive ability.
Fourth‐order phase field model with spectral decomposition for simulating fracture in hyperelastic material

Published: June 2021

AbstractWe present a fourth‐order phase field model for fracture behavior simulations of hyperelastic material undergoing finite deformation. Governing equations of the fourth‐order phase field model consist of the biharmonic operator of the phase field, which requires the second‐order derivatives of shape function. Therefore, a 5 × 5 Jacobian matrix of isoparametric transformation is constructed. Neo‐Hooken model and Hencky model are adopted as the material constitutive models. The spectral decomposition of stored strain energy is used to distinguish the contributions of tension and compression, and the corresponding stress tensor and constitutive tensors are derived, and subsequently, the numerical framework of modeling fracture with the fourth‐order phase field model is implemented in details. Several typical numerical examples are conducted to demonstrate the robustness and effectiveness of the fourth‐order phase field model in simulating the fracture phenomenon of rubber‐like materials.

Published: June 2021

AbstractThe effects of recycled crumb rubber up to 25% replacement of fine and coarse aggregates in two discreet gradations combined with 0% to 25% substitution of cement by silica fume were studied on the mechanical and fracture properties of self‐compacting concrete (SCC). For acquiring a diverse means of comparison, toughness index and energy absorbency of different mixtures were tested, and stress intensity factors of different mixtures were obtained. Additionally, statistical analyses were conducted to verify the validity of the results, and also, regression analyses were conducted to predict the values of flexural strength, toughness index, energy absorption, and fracture toughness of SCC mixtures. The results show that the addition of crumb rubber reduces the modulus of rupture, energy absorbency, and fracture toughness values, but the incorporation of silica fume can compensate for the losses. Conversely, there was a large rise in toughness index when adding crumb rubber.
