Published: July 2018

AbstractClimate change scenarios anticipate decrease of spring snow cover in boreal and subarctic regions. Forest lakes are abundant in these regions and substantial contributors of methane emissions. We performed an experiment on an anoxic frozen lake and observed that the removal of snow increased light penetration through the ice into the water modifying the microbial composition across depths. A shift in photosynthetic primary production was reflected by the increase of chlorophyll a and b concentrations in the upper depths of the water column, while Chlorobia, one of the key photosynthetic bacteria in anoxic lakes, shifted to lower depths. Moreover, a decrease in abundance of methanotrophs, such as Methylococcaceae, was noted concurrently to an increase in methane concentration in the water column. These results indicate that decrease of snow cover impacts both primary production and methane production/consumption, ultimately leading to increased methane emissions after spring ice off.

AbstractC4photosynthesis evolved repeatedly from the ancestral C3state, improving photosynthetic efficiency by ∼50%. In most C4lineages photosynthesis is compartmented between mesophyll and bundle sheath cells but how gene expression is restricted to these cell types is poorly understood. Using the C3modelArabidopsis thalianawe identifiedcis-elements and transcription factors driving expression in bundle sheath strands. Upstream of the bundle sheath preferentially expressedMYB76gene we identified a region necessary and sufficient for expression containing twocis-elements associated with the MYC and MYB families of transcription factors.MYB76expression is reduced in mutant alleles for each. Moreover, down-regulated genes shared by both mutants are preferentially expressed in the bundle sheath. Our findings are broadly relevant for understanding the spatial patterning of gene expression, provide specific insights into mechanisms associated with evolution of C4photosynthesis and identify a short tuneable sequence for manipulating gene expression in the bundle sheath.

Published: July 2018

AbstractAll available sequences of the three genome segments of Toscana virus with date and location of sampling were analysed using Bayesian phylodynamic methods. We estimate that extant Toscana virus strains had a common ancestor in the late 16th to early 17th century AD, in territories controlled by the Ottoman Empire, giving rise to an ancestral genotype A/B in north Africa and to genotype C in the Balkans. Subsequent spread into western Europe may have occurred during the period of European colonization of north Africa in the 19th and early 20th centuries AD, establishing genotypes A and B in Italy and Spain respectively. Very little positive evolutionary selection pressure is detectable in Toscana virus, suggesting that the virus has become well adapted to its human hosts. There is also no convincing evidence of reassortment between genome segments, despite genotypes A and B now co-circulating in several countries.
Female vocalizations predict reproductive output in Brown-headed Cowbirds (Molothrus ater)
Authors: Kohn Gregory M. 
Published: July 2018

ABSTRACTPair bonds are often maintained through the reciprocal and coordinated exchange of communicative signals. The ability to recognize and appropriately respond to a partner’s signals will define a pair’s ability to reproduce. Individual variation in responsiveness, by shaping the formation and maintenance of strong pair bonds, will ultimately influence an individual’s reproductive output. Throughout the breeding period, female cowbirds (Molothrus ater) respond to male song displays using a vocalization known as the chatter. In this study, we investigated whether variation in chatters remained repeatable across years and predicted reproductive performance. A flock of cowbirds housed in a large aviary complex was observed during the spring of 2011 to 2012. We recorded courtship interactions, including singing behavior for males, and chatters and eggs laid by females. The rate with which females responded to song using chatters remained consistent across years, with some females predictably responding to more songs using chatters than others. During 2012, chattering predicted the number of eggs females laid and her paired status. Paired females were more likely to respond to songs with chatters, and there was a strong positive relationship between the number of eggs laid and the proportion of songs she responded to using chatters. Overall, these findings suggest that individual variation in female vocal responsiveness is an important contributing factor to cowbird reproductive success.
Subsection corrosion inhibition of acidic-oxidized polymer degradant in offshore oil field
Authors: Zhu Yanhua , Zhao Liqiang , Liu Pingli , Yang Ming 
Published: July 2018

Purpose
This paper aims to introduce a method to reduce corrosion caused by acidic-oxidized polymer degradant through subsection injection with different inhibitor.

Design/methodology/approach
This paper introduced a method to reduce corrosion caused by acidic-oxidized polymer degradant through subsection injection with different inhibitor.

Findings
The experimental results indicated that the influence of pre-corrosion status on corrosion rate and effectiveness of corrosion inhibitor are significant. The corrosion inhibitors in both injection stage inhibited the corrosion process by preventing the contact of corrosive medium and steel surface through formation of a protective film on the surface of N80 steel. The corrosion rate of polymer degradant can be reduced to 0.63 g/m 2 h through subsection injection with different inhibitor.

Originality/value
This result will increase the production of polymer injection plugging wells through expanding the application of acidic-oxidized polymer degradant.
Village-level supply reliability of groundwater irrigation in rural China
Authors: Li Yanrong , Wang Jinxia , Huang Jikun , Adhikari Bihm , You Liangzhi 
Published: July 2018

Purpose
The purpose of this paper is to examine the status of the supply reliability of groundwater irrigation, and discuss how it is affected by climate change and tubewell density in rural China.

Design/methodology/approach
This study is based on a nine-province village survey and secondary climate data. A Tobit model (or censored regression model) was used to estimate the determinants of supply reliability of groundwater irrigation.

Findings
Results show that the supply reliability of groundwater irrigation was 89 percent on average in the past three years. The non-linear relationship in the econometric results revealed that the 30-year annual temperature significantly influenced the supply reliability of groundwater irrigation. When the temperature rises above the turning point (6.30°C), it shifts from a positive to a negative relationship with the supply reliability of groundwater irrigation. The 30-year annual temperature in eight of the nine provinces (i.e. except for Jilin Province) was higher than the turning point. If the temperature increases by 20°C in the future, other factors being constant, the supply reliability of groundwater irrigation will decline by 20 percent. However, if precipitation increases by 10 percent, the supply reliability of groundwater irrigation could improve by 3 percent, while reducing precipitation by 10 percent will lower the supply reliability of groundwater irrigation by 3 percent. Increasing the density of tubewells considerably improves the supply reliability of groundwater irrigation. However, although increasing the density of tubewells may yield enough groundwater for irrigation, this one-sided approach raises sustainability concerns.

Research limitations/implications
Although increasing the density of tubewells may ensure that enough groundwater is available for irrigation, such a conclusion is one sided, and sustainability concerns should be raised in assessing this method of creating supply reliability.

Originality/value
This paper improves the understanding of the impact of climate variables on agriculture irrigation and water supply reliability in the micro scale, and provides a scientific basis for relevant policy making.
Incentive mechanisms and hedging effectiveness – an experimental study
Authors: Zhang Lu , Wan Difang , Wang Wenhu , Shang Chen , Wan Fang 
Published: July 2018

PurposeThe purpose of this paper is to analyze the role of four different incentives in improving hedging effectiveness and propose an alternative regulatory mechanism for China’s futures market.Design/methodology/approachThe research method that this study uses is a laboratory experiment, and this study follows the basic norms of experimental research. In addition, this paper designs and conducts a game experiment between hedgers and futures brokerage firms (FBFs) under different incentive mechanisms.FindingsBy analyzing the experimental data, it is found that compared with other incentive mechanisms, hedgers’ willingness to hedge and FBFs’ regulatory intention are both significantly higher for the dynamic linkage updating mechanism, indicating that hedgers have a stronger willingness to follow their hedging plan, and FBFs are more responsible for their regulatory behaviors. Additionally, the dynamic linkage updating mechanism has a long-term impact on effective hedging in the futures market.Research limitations/implicationsThe findings suggest that the dynamic linkage updating mechanism is beneficial for effectively restricting both hedgers’ over-speculation and FBFs’ regulatory slack and improving the hedging efficiency of the futures market.Practical implicationsTo solve the problem of inefficient hedging in China’s futures market, i.e., hedgers’ over-speculation and FBFs’ passive collusion with hedgers, the regulators of China’s futures market should reform the existing incentives and adopt a dynamic linkage updating mechanism to encourage all the participants to actively improve hedging effectiveness.Originality/valueThis paper analyzes and verifies, for the first time, the role of the dynamic linkage updating mechanism in the investing behaviors of hedgers and the regulatory behaviors of future brokerage firms. The futures market experiment that was designed and used in this study is a pioneering and exploratory experiment that applies game theory and mechanism design theory to the field of behavioral finance.
Myths as errors and inventions: the shadow of tradition in pa praxis
Authors: Schmukler Ricardo 
Published: July 2018

Purpose
The purpose of this paper is to discuss the impossible segregation of founding myths from any actual understanding of life in common, the public good and PA theorizing. The notion of shadow as used by Robert Denhardt to designate the “other side” of rational motives in organizing fits well with the approach to PA myths here intended, in consonance with the theme of unity in apparent opposites and the “intensely meaningful acts of heroes and heroines” (Denhardt, 1981, p. xii). Finally, the questionable opposition between logos and myth will be reviewed along the discussion of the sacred and the secret in PA tradition.

Design/methodology/approach
The author examines PA myths and discusses conjectures and explanations.

Findings
PA founding myths are not false believes or illusionary entities but genuine precursors and effective backstage arrangers of theory and praxis. The processes of languaging, musicking and organizing, basic human traits and fundamental events for human life to occur and get structured as it does, cannot prescind from them. Myths are intertwined with reasons and desires, inseparable, coexisting in the unified and pluriversal forms of doing, knowing and valuing that configure human life. Nothing different corresponds to PA and its myths as key components of the processes of thought, action and judgment that constitute the public domain.

Originality/value
PA myths persist not only through the ages of the administrative state but through the transformations of thoughts also occurred in each theorist’s own life experience. At different times, situations and conditions all of us – the author guess – have addressed this or that PA myth for motives worth deserving the reiterated discussion. It was never the same discussion; it could not have been, it is not, and it will not ever be.
Breaching intellectual capital: critical reflections on Big Data security
Authors: La Torre Matteo , Dumay John , Rea Michele Antonio 
Published: July 2018

Purpose
Reflecting on Big Data’s assumed benefits, this study aims to identify the risks and challenges of data security underpinning Big Data’s socio-economic value and intellectual capital (IC).

Design/methodology/approach
The study reviews academic literature, professional documents and public information to provide insights, critique and projections for IC and Big Data research and practice.

Findings
The “voracity” for data represents a further “V” of Big Data, which results in a continuous hunt for data beyond legal and ethical boundaries. Cybercrimes, data security breaches and privacy violations reflect voracity and represent the dark side of the Big Data ecosystem. Losing the confidentiality, integrity or availability of data because of a data security breach poses threat to IC and value creation. Thus, cyberthreats compromise the social value of Big Data, impacting on stakeholders’ and society’s interests.

Research limitations/implications
Because of the interpretative nature of this study, other researchers may not draw the same conclusions from the evidence provided. It leaves some open questions for a wide research agenda about the societal, ethical and managerial implications of Big Data.

Originality/value
This paper introduces the risks of data security and the challenges of Big Data to stimulate new research paths for IC and accounting research.
Biofilms in the Spotlight: Detection, Quantification, and Removal Methods
Authors: González‐Rivas Fabián , Ripolles‐Avila Carolina , Fontecha‐Umaña Fabio , Ríos‐Castillo Abel Guillermo , Rodríguez‐Jerez José Juan 
Published: July 2018

AbstractMicroorganisms can colonize and subsequently form biofilms on surfaces, which protect them from adverse conditions and make them more resistant than their planktonic free‐living counterparts. This is a major concern in the food industry because the presence of biofilms has significant implications for microbial food contamination and, therefore, for the transmission of foodborne diseases. Adequate hygienic conditions and various preventive and control strategies have consequently been developed to ensure the provision of safe, good‐quality food with an acceptable shelf‐life. This review focuses on the significance of biofilms in the food industry by describing the factors that favor their formation. The interconnected process among bacteria known as “quorum sensing,” which plays a significant role in biofilm development, is also described. Furthermore, we discuss recent strategic methods to detect, quantify, and remove biofilms formed by pathogenic bacteria associated with food processing environments, focusing on the complexity of these microbial communities.
Elimination of p19ARF‐expressing cells protects against pulmonary emphysema in mice

Published: July 2018

AbstractSenescent cells accumulate in tissues during aging and are considered to underlie several aging‐associated phenotypes and diseases. We recently reported that the elimination of p19ARF‐expressing senescent cells from lung tissue restored tissue function and gene expression in middle‐aged (12‐month‐old) mice. The aging of lung tissue increases the risk of pulmonary diseases such as emphysema, and cellular senescence is accelerated in emphysema patients. However, there is currently no direct evidence to show that cellular senescence promotes the pathology of emphysema, and the involvement of senescence in the development of this disease has yet to be clarified. We herein demonstrated that p19ARF facilitated the development of pulmonary emphysema in mice. The elimination of p19ARF‐expressing cells prevented lung tissue from elastase‐induced lung dysfunction. These effects appeared to depend on reduced pulmonary inflammation, which is enhanced after elastase stimulation. Furthermore, the administration of a senolytic drug that selectively kills senescent cells attenuated emphysema‐associated pathologies. These results strongly suggest the potential of senescent cells as therapeutic/preventive targets for pulmonary emphysema.
A framework for applying learning analytics in serious games for people with intellectual disabilities
Authors: Nguyen Andy , Gardner Lesley A. , Sheridan Don 
Published: July 2018

AbstractThis paper proposes a systematic framework to integrate learning analytics into serious games for people with intellectual disabilities. Serious games for an inclusive learning environment need to be prudently designed with adaptive and measurable competencies to meet the needs of the target users. The recent emergence of learning analytics provides a capability to capture important data in real time from within the highly interactive nature of serious games to better understand and enhance the learning process. Although previous research has addressed different applications of learning analytics in serious games, few studies have investigated the needs of individuals with disabilities. This paper proposes a framework for serious games analytics specialised for people with intellectual disabilities (SGAPID) for the purpose of supporting the integration of learning analytics within serious games to create an inclusive learning environment. We provide a framework based on previous studies in both learning analytics, serious games and educational technologies for people with intellectual disabilities. The framework consists of three central components, namely learner profiling, learning adaptation and learning evaluation. It provides needed guidance for educational application developers and reflects the contemporary trends in educational technologies. The SGAPID framework will also be valuable for the design, implementation, evaluation and adaptation of serious games for inclusive learning and teaching at the group or individual level.
The opportunities and challenges of serious games for people with an intellectual disability
Authors: Terras Melody M. , Boyle Elizabeth A. , Ramsay Judith , Jarrett Dominic 
Published: July 2018

AbstractSerious Games (SG) are increasingly used to deliver education and training to support well‐being, social skills, independent living and online safety. This presents opportunities and challenges for users, developers and educational providers to ensure their benefits are available to all. People with intellectual disability (ID) experience high levels of digital exclusion. This article reviews and synthesises the literature on the use of SG with people with ID. Recent work indicates the importance of the psycho‐social profile of the gameplayer, mechanics and game context. We consider how these factors influence the inclusivity of SG and how they could be addressed. We demonstrate how a psychological perspective illuminates the impact of the user's psychological profile on game use and effectiveness, and explore how culture, personalisation and learning analytics can increase inclusivity of SG. We conclude by identifying wider challenges such as the need for multi‐disciplinary working and a more integrated, conceptual framework for games design which addresses diversity in learning needs.
Autistic youth in 3D game‐based collaborative virtual learning: Associating avatar interaction patterns with embodied social presence
Authors: Wang Xianhui , Xing Wanli , Laffey James M. 
Published: July 2018

AbstractThis study examines interaction patterns in a series of game activities for learning social skills by autistic youth in a 3D game‐based collaborative virtual learning environment (CVLE). Researchers studying collaborative learning have indicated the importance of social interactions and social presence. However, few studies have examined the relationship of avatar social interactions with embodied social presence in a 3D game‐based CVLE. Specifically, we examined avatar‐mediated verbal and nonverbal interactions by autistic youth in iSocial, a game‐based 3D CVLE for developing social competencies. How are avatar‐mediated verbal and nonverbal social interactions related to the extent of embodied social presence? Building on prior studies on embodied social presence (ESP) theory and the verbal and nonverbal social interaction framework, this paper aims to explore the link between the combination of verbal (appropriate and inappropriate) and nonverbal (avatar proximity, orientation, joint attention and gesture) interaction patterns and experienced ESP level. We report on the results of 3 cohorts of a total of 11 youth aged from 11 to 14 who were diagnosed with Autism Spectrum Disorder learning in 13 game activities in iSocial. The video data of the participants’ screen recordings were analyzed and coded based on the ESP theory and verbal and nonverbal social interaction framework. Through cluster analysis, the results identify distinct patterns of verbal and nonverbal interaction that are associated with different levels of embodied social presence. The findings of this study (1) shed light on the link between social interactions and embodied social presence and (2) provide a deeper understanding of how the unique spatial and visual characteristics of 3D CVLE and the design of game activities in 3D CVLE may transform collaborative learning, especially for autistic youth.

ObjectivesTo compare the olfactory bulb volumes (OBVs) in patients with chronic rhinosinusitis with nasal polyps (CRSwNP) to healthy individuals, and to assess the changes of the OBVs in patients with CRSwNP before and after the endoscopic sinus surgery (ESS) utilising magnetic resonance imaging (MRI) with specialised software.DesignThis is a prospective cohort study.SettingTanta University hospital (tertiary referral hospital), Egypt.ParticipantsThirty patients with CRSwNP (Group A) were compared with thirty healthy individuals (Group B) as regards the OBVs. Patients with CRSwNP underwent ESS where the Smell Identification Test‐40 (SIT‐40) and the OBVs were assessed pre‐operatively and at least 6 months postoperatively. Assessment of the OBVs was carried out using MRI with specialised software.Main outcome measuresAssessment of the volumetric changes of the olfactory bulbs in patients with CRSwNP before and after endoscopic sinus surgery utilise magnetic resonance imaging.ResultsThe OBVs were significantly smaller in Group A (58.94 ± 7.96 mm3 and 60.79 ± 8.14 mm3 on the right and left sides, respectively) as compared with the Group B (73.46 ± 8.54 mm3 and 72.96 ± 9.74 mm3 on the right and left sides, respectively). There was also a significant increase in the olfactory bulb volumes as well as improvement of the SIT‐40 6 months postoperatively in the Group A.ConclusionsThe olfactory bulb is characterised by neural plasticity, and its volume may be affected by the peripheral olfactory function.
