The olfactory gating of visual preferences to human skin and colors in mosquitoes
Authors: San Alberto Diego Alonso , Rusch Claire , Zhan Yinpeng , Straw Andrew D. , Montell Craig , Riffell Jeffrey A. 
Published: July 2021

AbstractMosquitoes track odors, locate hosts, and find mates visually. The color of a food resource, such as a flower or warm-blooded host, can be dominated by long wavelengths of the visible light spectrum (green to red for humans) and is likely important for object recognition and localization. However, little is known about the hues that attract mosquitoes or how odor affects mosquito visual search behaviors. We used a real-time 3D tracking system and wind tunnel that allowed careful control of the olfactory and visual environment to quantify the behavior of more than 1.3 million mosquito trajectories. We found that CO2induces a strong attraction to specific hues, including those that humans perceive as cyan, orange, and red. Sensitivity to orange and red correlates with mosquitoes’ strong attraction to the color spectrum of human skin, which is dominated by these wavelengths. Attraction was eliminated by filtering the orange and red bands from the skin color spectrum and by introducing mutations targeting specific long-wavelength opsins or CO2detection. Collectively, our results show that odor is critical for mosquitoes’ wavelength preferences and that the mosquito visual system is a promising target for inhibiting their attraction to human hosts.
Extracellular mechanical forces drive endocardial cell volume decrease during cardiac valve morphogenesis
Authors: Vignes Hélène , Vagena-Pantoula Christina , Prakash Mangal , Norden Caren , Jug Florian , Vermot Julien 
Published: July 2021

AbstractOrgan morphogenesis involves dynamic changes of tissue properties at the cellular scale. In addition, cells need to adapt to their mechanical environment through mechanosensitive pathways. How mechanical cues influence cell behaviors during morphogenesis, however, remains poorly understood. Here we studied the influence of mechanical forces during the formation of the atrioventricular canal (AVC) where cardiac valves develop. We show that in zebrafish the AVC forms within a zone of tissue convergence between the atrium and the ventricle which is associated with increased activation of the actomyosin meshwork and endocardial cell orientation changes. We demonstrate that tissue convergence occurs with a major reduction of endocardial cell volume triggered by mechanical forces and the mechanosensitive channels TRPP2/TRPV4. In addition, we show that the extracellular matrix component hyaluronic acid controls cell volume changes. Together, our data suggest that cell volume change is a key cellular feature activated by mechanical forces during cardiovascular morphogenesis. This work further unravels how mechanical forces and extracellular matrix can influence tissue remodeling in developing organs.
Democracy, accountability and audit: the creation of the UK NAO as a defence of liberty
Authors: Ferry Laurence , Midgley Henry 
Published: July 2021

PurposeThe study focusses on explaining why advocates for reform to state audit in the United Kingdom (UK) in the early 1980s, focussed on improving the links between the new National Audit Office (NAO) and Parliament, rather than on traditional notions of audit independence. The study shows how this focus on the auditor's link to Parliament depends on a particular concept of liberty and relates this to the wider literature on the place of audit in democratic society.Design/methodology/approachUnderstanding the issue of independence of audit in protecting the liberties and rights of citizens needs addressed. In this article, the authors investigate the creation of audit independence in the UK in the National Audit Act (1983). To do so, the authors employ a neo-Roman concept of liberty to historical archives ranging from the late 1960s to 1983.FindingsThe study shows that advocates for audit reform in the UK from the 1960s to the 1980s were arguing for an extension to Parliament's power to hold the executive to account and that their focus was influential on the way that the new NAO was established. Using a neo-Roman concept of liberty, the authors show that they believed Parliamentary surveillance of the executive was necessary to secure liberty within the UK.Research limitations/implicationsThe neo-Roman republican concept of liberty extends previous studies in considering the importance of audit for public accountability, the preservation of liberty and democracy.Practical implicationsPublic sector audit can be a fundamentally democratic activity. Auditors should be alert to the constitutional importance of their work and see parliamentary accountability as a key objective.Originality/valueThe neo-Roman concept of liberty extends previous studies in considering the importance of audit for public accountability, preservation of liberty and democracy.
A network of circular economy villages: design guidelines for 21st century Garden Cities
Authors: Liaros Steven 
Published: July 2021

PurposeThe purpose is to open the possibility for a research institute, perhaps in partnership with a local council and a major developer, to bring together skills necessary to prototype the CEV development model.Design/methodology/approachThis paper advances the development of a hypothetical, systems-based approach to the design and development of smart rural villages – a network of circular economy villages (CEVs). The method is to assimilate visionary ideas from 20th century town planning literature related to decentralisation and the development of new towns in rural areas, identifying key design principles. The present trajectory of infrastructure design and emerging development models are then analysed to modernise the design principles for implementation in the 21st century.FindingsThe availability of localised, renewable energy micro-grids potentially makes CEVs feasible and affordable. The shift to remote work and movement of people to regional areas suggests that this may be a desirable development form. This can only be confirmed through the development of a pilot project as proof of concept.Originality/valueThe proposed CEV development model applies circular economy strategies to every aspect of the smart rural village development including financing, ownership, spatial planning, design and material selection.
New derivative-free iterative family having optimal convergence order sixteen and its applications
Authors: Kaur Manpreet , Kumar Sanjeev , Kansal Munish 
Published: July 2021

PurposeThe purpose of the article is to construct a new class of higher-order iterative techniques for solving scalar nonlinear problems.Design/methodology/approachThe scheme is generalized by using the power-mean notion. By applying Neville's interpolating technique, the methods are formulated into the derivative-free approaches. Further, to enhance the computational efficiency, the developed iterative methods have been extended to the methods with memory, with the aid of the self-accelerating parameter.FindingsIt is found that the presented family is optimal in terms of Kung and Traub conjecture as it evaluates only five functions in each iteration and attains convergence order sixteen. The proposed family is examined on some practical problems by modeling into nonlinear equations, such as chemical equilibrium problems, beam positioning problems, eigenvalue problems and fractional conversion in a chemical reactor. The obtained results confirm that the developed scheme works more adequately as compared to the existing methods from the literature. Furthermore, the basins of attraction of the different methods have been included to check the convergence in the complex plane.Originality/valueThe presented experiments show that the developed schemes are of great benefit to implement on real-life problems.
Cultivating social capital: an exploratory analysis of business postgraduates in Ghana
Authors: Ayentimi Desmond Tutu , Hinson Robert Ebo , Burgess John 
Published: July 2021

PurposeThis paper, grounded on social capital and social networking theory, examines how postgraduate students in Ghana cultivate and utilise social resources towards career development.Design/methodology/approachFollowing a qualitative study design, the authors recruited and conducted interviews with postgraduate student-workers undertaking a two-year Master of Science in International Business.FindingsThere was an active engagement and consciously pre-plan mobilisation of social resources and utilisation of social resources among the postgraduates. Despite the diverse processes of social capital development identified, four important key themes emerged underpinning social capital mobilisation and utilisation: (1) the recognition of the importance of social capital acquisition, (2) the strong link between social capital and individual successes in employment and business opportunities, (3) the importance of the utilisation of social resources for emotional support and (4) the use of social capital to reinforce the individual social identity and recognition of an individual's worth.Practical implicationsThe authors offer a theoretical and practical contribution with a frame of understanding by demonstrating that there is more to social capital than economic gain.Social implicationsUnlike the findings from prior research in Africa, the strong institutional and cultural conditions did not constrain the key force of education and employability as drivers in attainment and social positioning. This is an interesting and positive finding from the research, especially in terms of the importance of providing educational opportunities to overcome institutional and cultural barriers to workforce participation and career development.Originality/valueSocial networks contribute to career success, and while the participants used social networks that reinforced ethnic and religious bonds, there is the opportunity to develop networks through other identity processes, especially education. Formal education imparts more than formal skills and qualifications. It provides the opportunity to access networks that transcend personal identity such as ethnicity and to get support for career development.
What’s not to like about evidence-based management: a hyper-rational fad?
Authors: Hulpke John F. , Fronmueller Michael P. 
Published: July 2021

Purpose
A topic currently receiving significant academic and practitioner attention is called evidence-based management. The purpose of this paper is to suggest that this approach is sometimes over-sold and may be a fad. Additionally, evidence-based management fails to fully recognize the importance of tacit knowledge, what Kahneman calls system 1. Evidence-based management does provide tools to better use what Kahneman calls system 2, rationality. Decision-makers need to take advantage of both rational and beyond rational processes.

Design/methodology/approach
This is an essay, it is not a report of a study. At this point in time, this paper needs thinking, reflection, pondering, more than a data-based study.

Findings
Advocates promote evidence-based management in part to help avoid fads, yet evidence-based management itself has many of the characteristics of a fad. Evidence-based management is based on an objective rational view of the world and suggests highly rational methods of decision-making. However, a rational fact-based might not give sufficient credit to instinct and feelings. Decision-makers should take into account facts, evidence, when making decisions, but not ignore intuition, hunches and feelings. This study is learning that decisions use a galaxy of approaches, with both cognitive and affective flexibility.

Research limitations/implications
As with any opinion-based paper, this lacks empirical support. Proponents ask us to believe in evidence-based management. Neither we, the authors of this paper, nor the proponents of evidence-based management can empirically support the ideas offered. An additional limitation is that the paper is written in one language, English. Translation into another language might yield different meanings.

Practical implications
There are advantages for scholars and practitioners to look at the best available evidence. There can be disadvantages in overlooking non-quantifiable factors.

Social implications
Those who use evidence-based management should also take into account feelings, ethics, aesthetics, creativity, for the betterment of society. To solve wicked problems one needs more than facts and rational analysis.

Originality/value
The overwhelming majority of those writing about evidence-based management are supporters. This study offers a different view. This paper brings new ideas and new thinking to both the extensive fad literature and the huge evidence-based management literature. Evidence-based management is discussed widely. Google Scholar lists more than two million papers in 2019, 2020 and 2021 on evidence-based management. Readers of this journal should critically evaluate this popular set of ideas.
Dividend policy, earnings management and the moderating effect of corporate governance in the French context
Authors: Ben Salah Olfa , Jarboui Anis 
Published: July 2021

Purpose
The purpose of this paper is to examine the moderating effect of corporate governance on the impact of earnings management on dividend policy.

Design/methodology/approach
In this paper, the authors selected French non-financial companies listed on the CAC All Tradable index during the 2008–2015 period. Feasible generalized least square regression method is used to estimate the econometric models.

Findings
The empirical results allowed the authors to confirm and/or reject certain hypotheses. First, the ownership concentration seems to positively moderate the impact of earnings management on dividend policy. Another conclusion that the authors have been able to draw is that the effect of earnings management on dividend policy is more favorable in the case of firms with a small director’s board.

Practical implications
Our results have shown that French firms run earnings to inform the market that they can distribute dividends. Therefore, we recommend that the various partners of the firm pay more attention to the governance mechanisms of these types of companies and, in particular, in countries where foreign investors suffer from weak legal protection (Easterbrook, 1984; Gomes, 2000; La Porta et al., 2000 and Athari et al., 2016). In fact, standardization bodies, the Ministry of Finance, external auditors and stock exchange organizer must focus on sophisticated governance mechanisms to ensure better quality of financial reporting.

Originality/value
To our knowledge, no other research has examined whether the impact of earnings management on dividend policy varies significantly with the moderating effect of certain governance mechanisms in France.
Incentive strategy about technology innovation based on knowledge ecological coupling in strategic emerging industry
Authors: Long Yue , Lu Lang , Liu Pan 
Published: July 2021

PurposeThe purpose of this paper is to solve the problem of low efficiency on knowledge resources allocation in the strategic emerging industry (SEI), an incentive model of technology innovation based on knowledge ecological coupling is designed.Design/methodology/approachFirst, a principal–agent model of knowledge inputs and a knowledge ecological coupling model based on an improved Lotka–Volterra model are constructed. In addition, a numerical example about Chongqing Yongchuan industrial park, the emulation analysis and the associated discussions are conducted to analyze the equilibriums of principal–agent in different knowledge inputs. Further, the paper analyzes the evolutionary equilibrium in knowledge ecological coupling and reveals the dual adjustments of the node organization on knowledge inputs.FindingsThus, this paper shows that by establishing the relationships of knowledge ecological coupling based on “mutualism and commensalism,” node organization raises the level of knowledge inputs; an incentive mode of “knowledge ecological coupling relationship + technology innovation chain” is conductive to substantially improving the efficiency of knowledge resource allocation, and to stimulate the vitality of node organization for technology innovation in the strategic emerging industry (SEI).Originality/valueThis paper contributes to the extant researches in two ways. First, this paper reveals the dual adjustments of the node organizations in inputting knowledge, which broadens the vision and borders of the researches on traditional knowledge management. The methods of the traditional principal–agent model and the knowledge input/output profit model are also expanded. Second, this paper verifies that applying the mode of “knowledge ecological coupling relationship + technology innovation chain” in practice is conducive to enhancing the efficiency of the cross-organizational knowledge allocation in the strategic emerging industry (SEI).
Sovereign wealth funds and corporate social responsibility: a comparison of Norway’s Government Pension Fund Global and Abu Dhabi Fund for Development
Authors: Velayutham Sivakumar , Hasan Rashedul 
Published: July 2021

PurposeThe purpose of this paper is to critically discuss the participation of sovereign wealth funds (SWFs) in the corporate social responsibility (CSR) programmes. Sovereign wealth funds in emerging economies are often involved in corporate social responsibility. However, the 1 Malaysian Development Berhad (1MDB) scandal illustrates the possible use of SWF as a vehicle for corruption and abuse.Design/methodology/approachThe primary objective is to develop good governance practices of CSR by SWFs that could limit corrupt practices. A case study approach is adopted to investigate the CSR involvement of two SWFs – Norway’s Government Pension Fund Global (GPFG) and Abu Dhabi Fund for Development (ADFD).FindingsThe finding shows that SWFs should not be directly involved in CSR. It is proposed that independent Non-government Organisations (NGOs), through a competitive funding model, could serve the CSR purpose of SWFs more effectively and bring socio-economic changes in emerging economies.Originality/valueThe funding model identifies the expected outcomes, priorities and uses of the funds. The funding committee should also be independent of the Board and transparent in its allocations.
Cognitive frames held by supply chain managers: implications for the management of sustainability in supply chains
Authors: Preuss Lutz , Fearne Andrew 
Published: July 2021

PurposeDespite the growing importance and complexity of modern supply chains, little scholarly attention has been devoted to cognitive processes in supply chain management (SCM). In particular, we know little about the structure of supply chain managers’ cognitive frames and how differences between frames affect sustainable supply chain management (SSCM).Design/methodology/approachGiven the relative scarcity of the topic, this paper uses a conceptual approach. Building on prior literature from cognitive psychology and related areas, it develops ideal types of cognitive frames with which supply chain managers approach sustainability-related decisions.FindingsThis study first develops three ideal-type cognitive frames – unidimensional, hierarchical and paradoxical. This paper then shows that it makes a difference which one of these a supply chain manager holds when addressing issues related to sustainable supply. Thereafter, this study discusses the antecedents that can explain why a manager holds a particular cognitive frame.Research limitations/implicationsThis paper represents one of the first analyses of how the structure of a supply chain manager’s cognitive frame impacts their firm’s sustainable supply initiatives. Although developed with regard to SSCM, the arguments have implications for other management areas too, not least for the education of future SCM professionals.Originality/valueGiven their boundary-spanning role, attention to the cognitive processes of supply chain managers is crucial to understanding the conditions under which firms can address sustainability challenges in their supply chains.
Characterisation of probiotic properties of yeast strains isolated from kefir samples
Authors: Goktas Hamza , Dikmen Hilal , Demirbas Fatmanur , Sagdic Osman , Dertli Enes 
Published: July 2021

AbstractThis study aimed to isolate and identify yeast species from kefir samples and to determine their probiotic characteristics in comparison with commercial probiotic yeast Saccharomyces boulardii. The microbial flora of traditional kefir samples were dominated by Saccharomyces cerevisiae and Kluyveromyces marxianus. Kefir isolates demonstrated higher auto‐aggregation, hydrophobicity and antioxidant properties compared to S. boulardii although S. boulardii demonstrated the highest survival rate under in␣vitro gastrointestinal digestion conditions followed by two kefir yeasts K. marxianus and Kazachstania unispora. Importantly, kefir isolates revealed strong antifungal activities against mould species except Penicillium roqueforti. These findings suggest probiotic and functional roles of yeast strains isolated from traditional kefir samples.
The Innovation and Reporting Consequences of Financial Regulation for Young Life‐Cycle Firms
Authors: ALLEN ABIGAIL , LEWIS‐WESTERN MELISSA F. , VALENTINE KRISTEN 
Published: July 2021

ABSTRACTFirm life‐cycle stage reflects a firm's current strategic direction toward exploration independent of age or size. We provide evidence that young life‐cycle firms are particularly vulnerable to negative innovation consequences from financial regulation but do not appear to experience any compensating financial reporting quality (FRQ) benefits. Using a generalized difference‐in‐differences design around Sarbanes Oxley Act of 2002 (SOX), we document a significant reduction in both research and development (R&D) spending and innovation outputs for young life‐cycle stage firms after regulation. Declines in innovation manifest both from the diversion of scarce resources and from the imposition of an organizational culture mismatched to the pursuit of explorative innovation, resulting in a less generalizable and less diversified patent portfolio. However, we find no evidence that improvements to FRQ materialize to offset these costs. Event study analyses suggest that this negative impact was expected by market participants, and postregulation returns confirm this expectation.
