Absorptive capacity and business performance
Authors: Liu Xueyuan , Zhao Haiyun , Zhao Xiande 
Published: August 2018

Purpose
The purpose of this paper is to examine the multiple paths of absorptive capacity’s (AC) effect on business performance (BP): direct effect and indirect effects through innovation and mass customization (MC).

Design/methodology/approach
The authors examined the role of innovation and MC capability on the relationship between AC and BP. Data from 278 Chinese firms in four manufacturing industries collected by questionnaire are used to empirically examine the proposed model by Structural equation modeling.

Findings
The results show that AC can directly enhance BP, and indirectly through innovation and MC capability. The study also finds that MC capability has a stronger mediating effect than innovation.

Originality/value
Prior studies have not yet built linkages between AC and BP with both innovation and MC’s effects. This study provides empirical evidence of the effects of AC on BP and three paths are discussed including AC’s direct effect and indirect effects through innovation and MC to firm’s BP. This study provides a new direction for executives to better understand the movement of knowledge along supply chain and in intra-organizational environment, and of the importance of innovation and MC capability since they are essential carriers for BP enhancement.
Leveraging collective intelligence: from univocal to multivocal representation of cultural heritage
Authors: Hajibayova Lala 
Published: August 2018

PurposeAfter reviewing cultural heritage institutions; crowdsourcing initiatives and tension between univocal and multivocal views of those who interact with cultural expressions, this paper argues that to support vibrant and effective crowdsourcing communities while ensuring the quality of the work of crowdsourcing project volunteers it is essential to reevaluate and transform the traditional univocal, top-down approach to representation and organization. The paper aims to discuss these issues.Design/methodology/approachThis conceptual paper applies Foucault’s power–knowledge construct and theories of representation to the processes and practices employed in cultural heritage crowdsourcing projects.FindingsViewed through the Foucauldian lens, cultural heritage professionals are regarded as active parts of the power–knowledge relationship due to their direct engagement in the representation, organization and dissemination of knowledge, exercised not only through the traditional role of cultural heritage institutions as gatekeepers of knowledge but, more importantly, through the power of representation and organization of the cultural heritage.Originality/valueThis paper provides a theoretical understanding of cultural heritage crowdsourcing initiatives and proposes a framework for multivocal representation of cultural heritage expressions in which the voices of volunteers have the same validity as the voices of cultural heritage professionals.
Servant leadership and the Scrum team’s effectiveness

Published: August 2018

PurposeScrum is a development methodology that has been rapidly gaining popularity over the last decade particularly for software development teams. The Scrum master is sometimes viewed as a servant leader of the Scrum team. The purpose of this paper is to investigate to what extent Scrum masters actually make use of servant leadership and how this impacts on the team’s effectiveness via mediating processes.Design/methodology/approachThe research followed a quantitative approach. An online questionnaire was prepared and completed by 71 Scrum team members (excluding Scrum masters) and 22 Scrum masters in more than ten organizations based in Western Cape, South Africa.FindingsScrum masters in this sample extensively used the servant leadership approach, but those who are also appointed as formal team leaders are seen to be considerably better servant leaders by team members. There is a moderately strong correlation between servant leadership of the Scrum master and team effectiveness. It was found that high levels of psychological safety do not necessarily translate into team performance.Research limitations/implicationsResearch was only performed at the unit level of analysis and not the team or organizational level. This was a cross-sectional study and variations over time were not considered.Practical implicationsThe results confirm the importance of servant leadership skills when identifying and developing Scrum masters, appointing the formal team leader role in Scrum teams and implementing Scrum practices effectively.Originality/valueAs could be established, this is the first time that the role of servant leadership in Scrum teams was formally investigated.
Does boardroom gender diversity affect the risk profile of acquiring banks?
Authors: Sghaier Adnène , Hamza Taher 
Published: August 2018

PurposeThe purpose of this paper is to investigate the influence of gender diversity on the boardroom and in top management positions on the risk profile (RP) of acquiring banks.Design/methodology/approachTo estimate the effect of mergers and acquisitions (M&A) in the RP of the acquirer, the authors will use the same methodology adopted by Vallascas and Hagendorff (2011), this method compares the variation of the RP of the acquirer to the level risk of control banks. To investigate how merger-related risk changes are affected by gender diversity, the authors use a linear regression.FindingsThe results show that, on average, bank mergers do not significantly affect the RP of the acquiring bank. However, the authors found that the proportion of women in the board standing reduces the RP of the acquiring bank. Overall, the authors observe evidence that the appearance of a female in top management is associated with lower bank risk. Moreover, the authors conclude that the relationship between the presence of at least three women on the board and the default risk of the acquiring bank is negative.Originality/valueThis finding suggests that in the M&A transactions, female directors are considerably more conservative than their male counterparts. Thus, the authors confirm the postulate that women are more risk averse and less overconfident than their male counterpart. The conclusions are of particular significance for the banking industry. The authors provide some support for the view that regulators should favor gender quotas in the board management of banks to reduce risk-taking behavior.

SummaryUnder methanogenic conditions, short‐chain fatty acids are common byproducts from degradation of organic compounds and conversion of these acids is an important component of the global carbon cycle. Due to the thermodynamic difficulty of propionate degradation, this process requires syntrophic interaction between a bacterium and partner methanogen; however, the metabolic strategies and behaviour involved are not fully understood. In this study, the first genome analysis of obligately syntrophic propionate degraders (Pelotomaculum schinkii HH and P. propionicicum MGP) and comparison with other syntrophic propionate degrader genomes elucidated novel components of energy metabolism behind Pelotomaculum propionate oxidation. Combined with transcriptomic examination of P. schinkii behaviour in co‐culture with Methanospirillum hungatei, we found that formate may be the preferred electron carrier for P. schinkii syntrophy. Propionate‐derived menaquinol may be primarily re‐oxidized to formate, and energy was conserved during formate generation through newly proposed proton‐pumping formate extrusion. P. schinkii did not overexpress conventional energy metabolism associated with a model syntrophic propionate degrader Syntrophobacter fumaroxidans MPOB (i.e., CoA transferase, Fix and Rnf). We also found that P. schinkii and the partner methanogen may also interact through flagellar contact and amino acid and fructose exchange. These findings provide new understanding of syntrophic energy acquisition and interactions.

OBJECTIVEDecompensated liver cirrhosis (LC) can negatively affect the outcome of endoscopic retrograde cholangiopancreatography (ERCP). We aimed to compare the efficacy and safety of ERCP in patients with clinically defined compensated and decompensated LC.METHODSIn a single tertiary hospital, 146 endoscopic sphincterotomy‐naive patients with LC who underwent ERCP between 2005 and 2016 were reviewed. Patients with LC who had experienced variceal bleeding, ascites or hepatic encephalopathy were included in the decompensated LC group. Cannulation, technical and clinical successes, and major post‐ERCP adverse events including bleeding, pancreatitis, cholangitis and perforation were compared between the two groups.RESULTSPatients were divided into compensated and decompensated LC groups. Their baseline characteristics were not different, except for comorbid malignancy (22.3 % vs 38.5%, P = 0.038) and preprocedural transfusion (7.4% vs 36.5%, P < 0.001). The cannulation (97,9% vs 94.2%, P = 0.348) and technical (95.7% vs 88.5%, P = 0.167) success rates were not different. The clinical success rate was lower in the decompensated LC group (95.7% and 78.8%, P = 0.003), mainly due to comorbid hepatobiliary malignancy. Post‐ERCP pancreatitis (6.4% vs 30.8%, P = 0.008) and cholangitis (18.1% vs 32.7%, P = 0.046) rates were higher in the decompensated LC group.CONCLUSIONSDespite lower clinical success rates due to comorbid hepatobiliary malignancy, ERCP in patients with decompensated LC is technically feasible. Because postprocedural cholangitis and pancreatitis are more frequent in patients with decompensated LC, greater procedural precautions are needed in these patients.
Estimating Streambank Erosion Rates with a GPS‐Based Video Mapping System
Authors: Hensley Kelsey J. , Ayers Paul D. 
Published: August 2018

AbstractStreambank erosion provides a direct supply of sediment to fluvial systems and significantly contributes to the total load in sediment impaired streams. The total amount and location of excessive streambank erosion must be determined to reduce the sediment supply and improve water quality within these impaired water bodies. The objective of our study was to integrate the Bank Assessment for Non‐point source Consequences of Sediment (BANCS) model with the Streambank Video Mapping System, a global positioning system‐based landscape‐scale data collection method, to estimate the total sediment load (SL) from streambank erosion over several river kilometers. This integrated methodology allowed us to identify erosion hotspots along a 20.4 km section of Upatoi Creek in Georgia. These streambank locations would be the highest priority sites for stream restoration efforts such as streambank stabilization, reestablishment of riparian vegetation, and floodplain reconnection. Our study reach had a SL per unit channel length (109 t/yr/km) comparable in magnitude to loading rates reported in the literature from other traditional BANCS assessments.

AbstractBackgroundPoor oral health in children with cardiac conditions can have negative effects on quality of life and increased risk of infective endocarditis. The aim of this study was to investigate the caries experience in children with cardiac conditions attending the Royal Children's Hospital, Melbourne.MethodsMedical and dental records of 428 children aged <12 years were examined. Cardiac and other medical diagnoses, decayed, missing and filled surfaces/teeth were recorded and analysed. Children referred for reasons other than caries management (NRCM) was analysed separately to address confounding of referral reason on caries experience.ResultsMean age of overall study population was 4.9 (SD 2.4) years, caries prevalence 52.1%, mean dmft 3.65 (SD 4.8), mean dmfs 6.19 (SD 11.3), enamel defects prevalence 29.2%. Mean age of NRCM group was 4.6 (SD 2.4) years, caries prevalence 37.5%, mean dmft 2.37 (SD 4.2), mean dmfs 4.22 (SD 9.4), enamel defects prevalence 23.0%. Untreated carious lesions accounted for 89.9% of caries experience. Caries experience was associated with low socio‐economic status, absence of comorbidity and enamel defect presence.ConclusionsHigh disease levels were observed. Age, socio‐economic status and enamel defects were associated with caries experience, not severity of cardiac diagnoses. Early referral for dental care and improved access should be facilitated.

AbstractMercury intoxication is a public health risk factor due to its hazardous effect to several organs, including the cardiovascular system. There is evidence of endothelial dysfunction after exposure to mercury, but the effects on endothelium‐dependent vasodilatation are still unknown. In the present study, we aimed to evaluate the chronic effects of high HgCl2 doses on the mechanisms of vasodilatation. Wistar rats were injected with HgCl2 (1st dose 10.86 μg/kg, and daily doses 0.014 μg/kg for 30 days i.m.), and saline was used as control. Mercury exposure reduced the acetylcholine‐induced vasodilatation in aortic rings, which was restored by incubation with antioxidant tiron. Inhibition of the NO synthase, Na+/K+‐ATPase and K+ channels indicates reduced participation of these factors. In the mercury group, there were an increased local anion superoxide and a reduced NO. The vasodilatation to exogenous NO was partially inhibited by co‐incubation with TEA plus tiron, suggesting that reduced NO bioavailability is the responsible to that decreased the participation of K+ channels. Moreover, there was an increased participation of the Na+/K+‐ATPase associated with an up‐regulation of its alpha‐1 subunit. In conclusion, reduced NO bioavailability plays a major role in the impaired participation of K+ channels and Na+/K+‐ATPase in the acetylcholine‐mediated relaxation, although sodium pump is up‐regulated probably as a compensatory mechanism.

Published: August 2018

AimResilience is rapidly gaining momentum in mental health literature. It provides a new understanding of the highly variable trajectories of mental illness, and has consistently been linked with improved mental health outcomes. The present review aims to clarify the definition of resilience and to discuss new directions for the field.MethodsAfter discussing the definition of resilience, this narrative review synthesizes evidence that identifies the specific protective factors involved in this process. This review also addresses the mechanisms that underlie resilience.ResultsRecent literature has clarified the three core components of resilience, which are the presence of an adversity or specific risk for mental illness; the influence of protective factors that supersede this risk; and finally, a subsequently more positive outcome than expected. Now that these are largely agreed upon, the field should move on to addressing other topics. Resilience is a dynamic process by which individuals utilize protective factors and resources to their benefit. It can vary within one individual across time and circumstance. It can also refer to good functional outcomes in the context of diagnosable illness. While previous research has focused on psychological resilience, it is essential that resilience is conceptualized across modalities.ConclusionsThe field should move towards the development of a multimodal model of resilience. Researchers should now focus on producing empirical research which clarifies the specific protective factors and mechanisms of the process, aligning with the core concepts of resilience. This growing, more homogeneous evidence base, can then inform new intervention strategies.
A fatigue crack nucleation model for anisotropic materials
Authors: Wu Xijia 
Published: August 2018

AbstractBased on Tanaka‐Mura's dislocation‐dipole pile‐up configuration, a formulation of mixed mode fatigue crack nucleation is derived using the Stroh formalism for generally anisotropic materials. The fatigue life is explicitly expressed as inversely proportional to the stored plastic energy, depending on the material's anisotropic elastic matrix F−1, surface energy, Burgers vector, and lattice resistance. The model has been shown to agree with experimental observation on critical slip planes in PWA 1493 single crystal Ni‐base superalloy.
Continuous fatigue damage prediction of a rubber fibre composite structure using multiaxial energy‐based approach
Authors: Gosar Ales , Nagode Marko , Oman Simon 
Published: August 2018

AbstractThis paper details an advanced method of continuous fatigue damage prediction of rubber fibre composite structures. A novel multiaxial energy‐based approach incorporating a mean stress correction is presented and also used to predict the fatigue life of a commercial vehicle air spring. The variations of elastic strain and complementary energies are joined to form the energy damage parameter. Material parameter α is introduced to adapt for any observed mean stress effect as well as being able to reproduce the well‐known Smith‐Watson‐Topper criterion. Since integration to calculate the energies is simplified, the approach can be employed regardless of the complexity of the thermo‐mechanical load history. Several numerical simulations and experimental tests were performed in order to obtain the required stress‐strain tensors and the corresponding fatigue lives, respectively. In simulations, the rubber material of the air spring was simulated as nonlinear elastic. The mean stress parameter α, which controls the influence of the mean stress on fatigue life, was adjusted with respect to those energy life curves obtained experimentally. The predicted fatigue life and the location of failure are in very good agreement with experimental observations.
Ancient matter, new‐fashioned shapes: Time as object in Shackerley Marmion's The Antiquary
Authors: Gibbons Zoe 
Published: August 2018

AbstractShackerley Marmion's comedy The Antiquary (written 1635–36, printed 1641) presents two characters who waste time by measuring it. Veterano, the titular antiquary, spends his days idolizing his collection of ersatz artifacts; the fop Petrutio prizes his pocket watch because it allows him to ‘consume [his] hours’. Other early modern English authors criticized the vogue for pocket watches and the growing popularity of antiquarian study, but Marmion's originality lies in the connection he draws between the two trends: both Veterano and Petrutio value the material trappings of time over the actions that unfold within it. Through Petrutio, Marmion questions the role of technology in preventing idleness; through Veterano, he challenges the assumption that antiquarian study can produce smooth continuities between a troubled present and a nobler past. Though modern scholarship has neglected Marmion's small body of work, The Antiquary deserves further study as a portrait of the temporal concerns of Caroline England: youth and age; antiquity and horology; and the uses and abuses of time.

Published: August 2018

AbstractTiger beetles are a remarkable group that captivates amateur entomologists, taxonomists and evolutionary biologists alike. This diverse clade of beetles comprises about 2300 currently described species found across the globe. Despite the charisma and scientific interest of this lineage, remarkably few studies have examined its phylogenetic relationships with large taxon sampling. Prior phylogenetic studies have focused on relationships within cicindeline tribes or genera, and none of the studies have included sufficient taxon sampling to conclusively examine broad species patterns across the entire subfamily. Studies that have attempted to reconstruct higher‐level relationships of Cicindelinae have yielded conflicting results. Here, we present the first taxonomically comprehensive molecular phylogeny of Cicindelinae to date, with the goal of creating a framework for future studies focusing on this important insect lineage. We utilized all available published molecular data, generating a final concatenated dataset including 328 cicindeline species, with molecular data sampled from six protein‐coding gene fragments and three ribosomal gene fragments. Our maximum‐likelihood phylogenetic inferences recover Cicindelinae as sister to the wrinkled bark beetles of the subfamily Rhysodinae. This new phylogenetic hypothesis for Cicindelinae contradicts our current understanding of tiger beetle phylogenetic relationships, with several tribes, subtribes and genera being inferred as paraphyletic. Most notably, the tribe Manticorini is recovered nested within Platychilini including the generaAmblycheilaSay,OmusEschscholtz,PicnochileMotschulsky andPlatychileMacleay. The tribe Megacephalini is recovered as paraphyletic due to the placement of the monophyletic subtribe Oxycheilina as sister to Cicindelini, whereas the monophyletic Megacephalina is inferred as sister to Oxycheilina, Cicindelini and Collyridini. The tribe Collyridini is paraphyletic with the subtribes Collyridina and Tricondylina in one clade, and Ctenostomina in a second one. The tribe Cicindelini is recovered as monophyletic although several genera are inferred as para‐ or polyphyletic. Our results provide a novel phylogenetic framework to revise the classification of tiger beetles and to encourage the generation of focused molecular datasets that will permit investigation of the evolutionary history of this lineage through space and time.
