Controlling evolutionary dynamics to optimize microbial bioremediation
Authors: Shibasaki Shota , Mitri Sara 
Published: July 2019

AbstractSome microbes have a fascinating ability to degrade compounds that are toxic for humans in a process called bioremediation. Although these traits help microbes survive the toxins, carrying them can be costly if the benefit of detoxification is shared by all surrounding microbes, whether they detoxify or not. Detoxification can thereby be seen as a public goods game, where non-degrading mutants can sweep through the population and collapse bioremediation. Here, we constructed an evolutionary game theoretical model to optimize bioremediation in a chemostat initially containing “cooperating” (detoxifying) microbes. We consider two types of mutants: “cheaters” that do not detoxify, and mutants that become resistant to the toxin through private mechanisms that do not benefit others. By manipulating the concentration and flow rate of a toxin into the chemostat, we identified conditions where cooperators can exclude cheaters that differ in their private resistance. However, eventually, cheaters are bound to invade. To overcome this inevitable outcome and maximize detoxification efficiency, cooperators can be periodically reinoculated into the population. Our study investigates the outcome of an evolutionary game combining both public and private goods and demonstrates how environmental parameters can be used to control evolutionary dynamics in practical applications.
Does Sleep Protect Memories Against Interference? A Failure to Replicate
Authors: Bailes Carrie , Caldwell Mary , Wamsley Erin J. , Tucker Matthew A. 
Published: July 2019

AbstractAcross a broad spectrum of memory tasks, retention is superior following a night of sleep compared to a day of wake. However, this result alone does not clarify whether sleep merely slows the forgetting that would otherwise occur as a result of information processing during wakefulness, or whether sleep actually consolidates memories, protecting them from subsequent retroactive interference. Two influential studies (Ellenbogen, et al., 2006, 2009) suggested that sleep protects memories against the subsequent retroactive interference that occurs when participants learn new yet overlapping information (interference learning). In these studies, interference was much less detrimental to memory following a night of sleep compared to a day of wakefulness, a finding that provided strong evidence that sleep supports this important aspect of memory consolidation. In the current well-powered replication study, we repeated the protocol of Ellenbogen, et al. (2009) and, additionally, we examined the impact of intrinsic motivation on performance in sleep and wake participants. We were unable to replicate the finding that sleep protects memories against retroactive interference, with the detrimental effects of interference learning being essentially the same in wake and sleep participants. We also found that while intrinsic motivation benefitted task acquisition it was not a modulator of sleep-wake differences in memory processing. These finding of this replication study draw into question the claim that sleep protects memories against the effects of retroactive interference, and moreover, they highlight the importance of replicating key findings in the study of sleep’s impact on memory processing before drawing strong conclusions that drive the direction of future research.

AbstractOsteomyelitis, or bone infection, is often induced by antibiotic resistant Staphylococcus aureus strains of bacteria. Although debridement and long-term administration of antibiotics are the gold standard for osteomyelitis treatment, the increase in prevalence of antibiotic resistant bacterial strains limits the ability of clinicians to effectively treat infection. Bacteriophages (phages), viruses that effectively lyse bacteria, have gained recent attention for their high specificity, non-toxicity, and the low likelihood of resistance development by pathogens. Previously, we have shown that CRISPR-Cas9 genomic editing techniques could be utilized to expand bacteriophage host range and enhance bactericidal activity through modification of the tail fiber protein, as well as improve safety with removal of major virulence genes. In a dermal infection study, these CRISPR-Cas9 phages reduced bacterial load relative to unmodified phage. Thus, we hypothesized this bacteriophage would be effective to mitigate infection from a biofilm forming S. aureus strain in vitro and in vivo. In vitro, qualitative fluorescent imaging demonstrated superiority of phage to conventional vancomycin and fosfomycin antibiotics against S. aureus biofilm. Quantitative antibiofilm effects increased over time for fosfomycin, phage, and fosfomycin-phage (dual) therapeutics delivered via alginate hydrogel. We developed an in vivo rat model of osteomyelitis and soft tissue infection that was reproducible and challenging and enabled longitudinal monitoring of infection progression. Using this model, phage (with and without fosfomycin) delivered via alginate hydrogel were successful in reducing soft tissue infection but not bone infection, based on bacteriological, histological, and scanning electron microscopy analyses. Notably, the efficacy of phage at mitigating soft tissue infection was equal to that of high dose fosfomycin. Future research may utilize this model as a platform for evaluation of therapeutic type and dose, and alternate delivery vehicles for osteomyelitis mitigation.
Proliferation in the epiblast-hypoblast layers of the primitive-streak chick embryoblast in response to epidermal growth factor
Authors: Cunningham Francis O. 
Published: July 2019

AbstractThe reaction of twenty four hour old primitive streak chick embryoblasts exposed to epidermal growth factor was compared with non-exposed controls. After 24-36 hours incubation, proliferation up to 5-6 cell layers in thickness of the epiblast-hypoblast layers was evident in the EGF exposed embryo blasts. This compared with the normally expected one cell layer in thickness at this stage of development.
Readability of integrated reports: an exploratory global study
Authors: Stone Gerard William , Lodhia Sumit 
Published: July 2019

Purpose
A goal of integrated reporting (IR) under the International Integrated Reporting Council (IIRC)’s leadership is to provide clearly written, comprehensible and accessible information. In light of this objective, the purpose of this paper is to explore the readability and accessibility of integrated reports, an issue magnified by the IIRC’s continual commitment to clear and readable report language, and its intention for IR to become the corporate reporting norm.

Design/methodology/approach
In a whole text software facilitated analysis, the study utilises readability measures and supplementary measures of reader accessibility in a multi-year analysis of a large sample of global integrated reports sourced from the IIRC examples database.

Findings
The findings highlight the low readability of analysed integrated reports and indicate that readability is not improving. The supplementary measures suggest sub-optimal use of visual communication forms and overuse of structural presentation techniques which may contribute to reader accessibility of the analysed reports.

Research limitations/implications
The study extends readability analysis to an emerging corporate reporting phenomenon and its findings contribute to the growing IR literature. The study applies supplementary measures of reader accessibility which advance the methods available to assess the communication efficacy of integrated and other corporate reports.

Practical implications
The analysis of the readability and accessibility of integrated reports in the study indicates that the IIRC’s goal of clear, comprehensible and accessible reporting is not reflected by reporters’ practices. This has implications for the IIRC, reporting organisations, report readers and regulators.

Originality/value
The study represents the first large-scale analysis of the readability and accessibility of global integrated reports.
Climate-responsive design strategy for Erbil city
Authors: Vatan Kaptan Meltem 
Published: July 2019

Purpose
The purpose of this paper is to investigate passive techniques used in traditional and indigenous architecture in order to decrease energy use in the buildings and to increase thermal and users’ comfort. The city of Erbil is explored where in the rapid transformation and import of Western architectural styles and materials have resulted in ignorance of climate-responsive tradition existing in the city since thousands of years.

Design/methodology/approach
In order to propose a design strategy for modern residential buildings in Erbil city, a descriptive and interpretative approach is used as a methodology of this study. A literature review is done to explore the traditional use of passive techniques, and Waziran district of the city is analyzed and used as a pilot site in this study.

Findings
Due to the shortage of electric power in the city, residential buildings have limited access to electric power. Therefore, thermal comfort and reduction of the energy use in residential buildings have become vital for Erbil. The use of passive techniques in architectural design will help to reduce energy dependency.

Research limitations/implications
This study is limited to residential function in Erbil. Waziran district is used for the design proposals where dwellings are in a row context. The proposals are made on a geometrical basis and plan organization; however, the selection of construction materials is not included.

Originality/value
There is a proposal to reduce the use of electricity, which currently has limited access in Erbil city.
How do CEOs communicate on Twitter? A comparative study between Fortune 200 companies and top startup companies
Authors: Yue Cen April , Thelen Patrick , Robinson Katy , Men Linjuan Rita 
Published: July 2019

Purpose
The purpose of this paper is to compare Fortune 200 and top startup chief executive officers’ (CEOs) communication strategies on Twitter and the effectiveness of these strategies in influencing public engagement. Specifically, guided by the dialogic communication theory and social presence theory, this study explored CEOs’ use of dialogic communication, social presence strategies and message tactics. Additionally, public engagement on Twitter measured by total number of likes, retweets and comments was associated with communication strategies utilized by CEOs.

Design/methodology/approach
This study employed the quantitative content analysis. A total sample of 720 posts from 36 CEOs were selected and analyzed. Drawing from prior studies, a coding scheme was developed and employed during the coding process. Two authors of this study served as coders and reached satisfactory inter-coder reliability. A series of χ2 tests and negative binomial regressions were conducted for data analysis.

Findings
Neither Fortune 200 CEOs nor top startup CEOs fully utilized dialogic principles for Twitter communication. Although Fortune CEOs seemed to be experts in strategically tailoring messages and therefore present themselves on Twitter in a friendly manner, startup CEOs demonstrated a higher level of authenticity, animation and informality. Findings are mixed regarding the direction of associations between dialogic principles and public engagement.

Originality/value
This study expands the application of dialogic principles in examining online executive communication and its influence in public engagement on Twitter. This study was among the first that examined executive leadership communication in the context of social media setting. In this sense, the study shifted the internal focus of leadership research to investigating leaders’ interaction with a variety of online publics.
Government compensation and costs of non-competition guarantee for PPP rental retirement villages
Authors: Liu Shijing , Jin Hongyu , Liu Chunlu , Xie Benzheng , Mills Anthony 
Published: July 2019

Purpose
Targeting public–private partnership (PPP) rental retirement villages, the purpose of this paper is to bring forward the solution of insufficient research in a non-competitive guarantee (a restrictive agreement) towards the compensation and guarantee costs in consideration of benefit redistribution if the governments are unable to keep the promise on guarantee provision.

Design/methodology/approach
Real option principles are applied to assess the public–private investment proportions and the expected return rates of the private sector in a non-competitive guarantee and analyse their effects on the public–private benefit and risk allocations as well as the success of the project. Instead of granting direct capital support, this research accomplishes the compensation of non-competition guarantee by adjusting the project benefit distribution ratios between the government and the private sector to achieve the option value of the guarantee. An empirical example with alternative scales, which is developed from an existing rental village in Geelong, is used to numerically verify the research process.

Findings
The results illustrate that the option value of the non-competition guarantee plays an important role in supporting the implementation of the PPP rental retirement village projects. The option value of the non-competition guarantee has a close relationship with the guarantee level and the government guarantee cost, which is positively correlated with the guarantee level and negatively correlated with the government guarantee cost. To reduce the government guarantee cost, the government should carefully determine the public–private investment proportion, appropriately control the return rate of the private sector and approve the construction of the new project after the investment recovery of the private sector.

Research limitations/implications
This research mainly focusses on the economic loss of the government due to the guarantee responsibility. Further research could be conducted to determine the guarantee level more precisely and take the social cost of the government guarantees into consideration.

Originality/value
This research is the first attempt to investigate the government compensation and costs of non-competition guarantee for PPP rental retirement village projects and will enhance the understanding of the nature of PPP applications. The evaluation process and the implementation of the compensation through the adjustment of benefit distribution provides a comprehensive method to analyse the non-competition guarantee of PPP projects and help the parties negotiate in good faith to agree on a method of redress.

Hybrid dispute resolution model for migrant-host communities
Authors: Pely Doron , Luzon Golan 
Published: July 2019

PurposeThe purpose of this paper is to locate, describe and analyze the differences between the way migrants from communal cultures and local communities in Western Europe resolve intra-communal and inter-communal conflicts, and to use the findings to propose a hybrid alternative model that may be able to bridge across identified differences. Such a hybrid model will facilitate enhanced integration and adaptation between host and migrant communities, contributing to improved conflict resolution outcomes.Design/methodology/approachThis paper starts with an exploration, review and analysis of existing relevant literature describing refugee/migrant–host community interactions and their consequences. The second stage includes review and analysis of relevant alternative dispute resolution (ADR) literature. The third stage undertakes an examination and analysis of the practices identified in stage two, and the fourth stage proposes a method that uses potentially “bridging” practices by incorporating useful and relevant elements from host and refugee communities’ ADR mechanisms, in a way that may help resolve inter-communal disputes.FindingsThe paper demonstrates significant differences between host and migrant communities’ dispute resolution practices and the integrability of relevant ADR approaches toward creating a usable, hybrid, bridging approach to handle inter-communal conflicts.Research limitations/implicationsThe paper proposes a hybrid “bridging” host–refugee inter-communal conflict management model. The proposed model should be tested to prove feasibility and viability.Practical implicationsShould the proposed model prove useful, the practical implications may lead to the construction and use of different (hybrid) conflict management mechanisms in appropriate communities. Such mechanisms may lead to a reduction in the number and severity of inter-communal conflicts.Social implicationsA reduction in inter-communal conflicts within the framework of a host–migrant interface may have strong positive outcome to inter (and intra) communal relations and may reduce friction, crime, marginalization, hostility and radicalization.Originality/valueThe paper highlights the challenges to both migrant and host communities when it comes to finding a common ground for resolving inter-communal disputes and offers a pragmatic hybrid model to bridge cultural and functional gaps and help promote mutually satisfactory outcomes.

Court referral and Nigeria's Financial Regulation Advisory Council of Experts (FRACE)
Authors: Mustapha Zakariya , Kunhibava Sherin , Muneeza Aishath 
Published: July 2019

PurposeThis paper aims to highlight resolution of Islamic finance dispute by common law-oriented courts in Nigeria with respect to Sharīʿah non-compliance and legal risks thereof, as well as the lesson to learn from Malaysia in that regard. This is with view to ensuring Sharīʿah compliance and legal safety of Islamic finance practice as prerequisites for sustainability of the Nigerian Islamic finance industry.Design/methodology/approachA qualitative method was used; interviews were conducted with different categories of experts and primary data collected in relation to Sharīʿah non-compliance and legal risks in adjudicating Islamic finance dispute by civil courts and the role of expert advice as basis for court referral to Financial Regulation Advisory Council of Experts. A doctrinal approach was adopted to analyse relevant legislative provisions and content analysis of secondary data relevant to applicable provisions in matters of finance before civil courts.FindingsThe paper discovers an indispensable role of conventional financial regulations in sustaining Islamic finance industry. Appropriate laws for Islamic finance under the conventional framework foster legal safety and Sharīʿah compliance of Islamic finance activities in related cases handled by courts. Nigeria civil courts can aid sustainability of Islamic finance when so equipped and enabled by laws that address apparent Sharīʿah non-compliance and legal risks in judicial dispute resolution. Inadequate legal provisions for dispute resolution breeds Sharīʿah non-compliance and legal risks in Islamic finance, undermine its prospects and stand inimical to its sustainability.Research limitations/implicationsThis research is limited by its focus on Sharīʿah non-compliance and legal risks alone, which emanate mainly from judicial resolution of Islamic finance dispute by Nigerian civil courts.Practical implicationsThis research seeks to motivate a determined and deliberate regulatory action and change in approach towards addressing apparent risks associated with Islamic finance while resolving disputes therein by civil courts. It has implications on common law jurisdictions generally that adopt similar approach as Nigeria's while introducing Islamic finance into their conventional finance framework.Originality/valueDispute resolution and other regulatory functions of civil courts are important to Islamic finance though apparently overlooked while introducing Islamic finance in Nigeria as in other emerging jurisdictions. This research ascertains the role of the civil courts as indispensable for Islamic Financial Institution (IFIs) operations and demonstrates that such courts are needed for the development and sustainability of Islamic finance industry. The research demonstrates the end-to-end requirement of Sharīʿah compliance of Islamic financial transactions as absolute and needs be ensured and guarded at dispute resolution level by properly equipped courts.
