Sexualization of the work environment and emotional exhaustion
Authors: Bui Hong T.M. , Pinto Jonathan , Srivastava Abhishek 
Published: April 2019

PurposeThe purpose of this paper is to explore the relationship between sexualization of the work environment and emotional exhaustion, and develop some key antecedents of sexualization of the work environment. It was conducted in an emerging society, India, which has a high rate of crime against women, particularly related to sexual harassment and sexual assault.Design/methodology/approachTo test the hypotheses, structural equation modeling was performed. The hypotheses were tested with data from 1,098 white collar workers in India in three ways.FindingsContact with other gender and flexible work arrangements were positively associated with sexualization of the work environment; and sexualization of the work environment was positively associated with emotional exhaustion. In addition, sexualization of the work environment mediated the relationship between the two antecedent variables and emotional exhaustion.Research limitations/implicationsThere is a possible bias arising from the use of cross-sectional data. However, a number of methods were implemented to minimize it, including survey design and data analysis.Practical implicationsThe study offers some important suggestions for workplaces with a greater proportion of young male employees, particularly in a societal context like India.Originality/valueThe paper provides evidence of the negative impact of sexualization of the work environment, and thereby contributes to current understanding of the “dark side” of behavior at work that might have significant impact on society.

Authors: Cheng Jao Hong , Lin Li Wei , Lee Liang Chien 
Published: April 2019

PurposeThe purpose of this paper is to examine the factors influencing ambidextrous governance and risk management on repurchase intention in social commerce.Design/methodology/approachA novel research model comprises nine research hypotheses with six constructs, including three dimensions of social capital (structural, relational and cognitive), contracts, relational risk and repurchase intention. The hypotheses are tested on data collected from 395 usable responses in Taiwan, using structural equation modeling.FindingsThe findings of this study indicate that online merchants should reinforce their collaborative behavior and activities to improve ambidextrous governance mechanisms, and thus enhance repurchase intention.Research limitations/implicationsThe resultant findings only reflect the setting of Taiwan’s social commerce marketplace. With the research model developed, future research on cross-country studies of various forms of social networking sites would be worth conducting to determine regional differences in the development of social commerce activities.Originality/valueAmbidextrous governance mechanisms have been gaining attention in buyer–supplier relationships. Extending ambidexterity research to the social commerce domain, the authors focus on ambidextrous governance that can include social and contractual governance elements.
Tactile sensing for surgical and collaborative robots and robotic grippers
Authors: Bogue Robert 
Published: April 2019

Purpose
This paper aims to illustrate the increasingly important role played by tactile sensing in robotics by considering three specific fields of application.

Design/methodology/approach
Following a short introduction, this paper first provides details of tactile sensing principles, technologies, products and research. The following sections consider tactile sensing applications in robotic surgery, collaborative robots and robotic grippers. Finally, brief conclusions are drawn.

Findings
Tactile sensors are the topic of an extensive and technologically diverse research effort, with sensing skins attracting particular attention. Many products are now available commercially. New generations of surgical robots are emerging which use tactile sensing to provide haptic feedback, thereby eliminating the surgeon’s total reliance on visual control. Many collaborative robots use tactile and proximity sensing as key safety mechanisms and some use sensing skins. Some skins can detect both human proximity and physical contact. Sensing skins that can be retrofitted have been developed. Commercial tactile sensors have been incorporated into robotic grippers, notably anthropomorphic types, and allow the handling of delicate objects and those with varying shapes and sizes. Tactile sensing uses will inevitably increase because of the ever-growing numbers of robots interacting with humans.

Originality/value
This study provides a detailed account of the growing use of tactile sensing in robotics in three key areas of application.
Internet and prevalence of relative thinking
Authors: Thota Sweta Chaturvedi , Kinra Ritwik 
Published: April 2019

Purpose
Research demonstrates that individuals display relative thinking – the tendency to consider relative savings rather than just absolute savings in their decisions to search for a deal or purchase an item. This paper aims to review empirical and analytical literature on relative thinking, perceived search costs and price savings to propose and test a conceptual model of relative thinking.

Design/methodology/approach
Through two studies, the paper tests whether individuals display relative thinking when shopping across stores vs online and how they perceive search and time spent in pursuing savings. Both studies are adaptations of the classic jacket-and-calculator scenario study (Tversky and Kahneman, 1981).

Findings
Results show attenuation of the robust relative thinking phenomenon over the internet compared to shopping across stores. Individuals exhibit increased price sensitivity for both low and high relative savings conditions on the internet but demonstrate price sensitivity only in the high relative savings condition in the store shopping contexts. Diagnostic measures pertaining to the attractiveness of savings and the perceptions of search costs corroborate the support for relative thinking across stores but not over the internet.

Originality/value
These results lend weight to the central claim in this paper that the internet marks a new boundary condition for the relative thinking phenomenon in marketing literature. Theoretical and managerial implications of the findings, the limitations of the studies and future research opportunities are discussed.
Participative leadership and job satisfaction
Authors: Chan Simon C.H. 
Published: April 2019

PurposeThe purpose of this paper is twofold: first, to examine the relationships between participative leadership and employees’ work engagement and job satisfaction; and second, to determine whether the level of fun experienced at work moderates the effect of participative leadership on job satisfaction.Design/methodology/approachThe participants were 177 employees in a retailing store in Hong Kong. Hierarchical multiple regression was conducted with the control variables to ascertain the relationships among participative leadership, level of fun experienced at work, work engagement and job satisfaction.FindingsThe results indicated that participative leadership was positively related to employees’ work engagement and job satisfaction. Employees’ work engagement mediated the relationship between participative leadership and job satisfaction. This positive relationship between participative leadership and job satisfaction was stronger when employees had more fun at work.Research limitations/implicationsThe generalizability of the data was limited, as the characteristics of participants in a retail store are distinct from others in the service industry.Practical implicationsThis paper’s findings imply that participative leaders can engage in role modeling by providing more fun workplace activities to employees, which will increase their work engagement and job satisfaction.Originality/valueThe findings help to explain the relationship between participative leadership and job satisfaction, provide a better understanding of leadership management styles and show that participative leaders who engage employees in fun activities in the workplace can increase employees’ job satisfaction.
Research on soldering AlN ceramics with Cu substrate using Sn-Ag-Ti solder
Authors: Koleňák Roman , Kostolný Igor , Drápala Jaromír , Kusý Martin , Pašák Matej 
Published: April 2019

Purpose
This study aims to solder AlN ceramics with a Cu substrate using an active type Sn-Ag-Ti solder. Soldering was performed with power ultrasound. The Sn3.5Ag2Ti alloy was first studied.

Design/methodology/approach
It was found to contain a Sn matrix, where both Ag phase – ɛ-Ag3Sn – and Ti phases ɛ-Ti6Sn5 and Ti2Sn3 – were identified. Ti contained in these phases is distributed to the interface with ceramic material. A reaction layer was thus formed. This layer varies in thickness from 0.5 to 3.5 µm and ensures the wettability of an active solder on the surfaces of ceramic materials.

Findings
X-ray diffraction analysis proved the presence of new NTi and AlTi2 phases on the fractured surface. Sn plays the main role in bond formation when soldering the Cu substrate with Sn-Ag-Ti solder. The Cu3Sn and Cu6Sn5 phases, which grow in direction from the phase interface to solder matrix, were found in all cases within the solder/Cu substrate interface. The combination of AlN ceramics/Cu joint maintained a shear strength of 29.5 MPa, whereas the Cu/Cu joint showed a somewhat higher shear strength of 39.5 MPa.

Originality/value
The present study was oriented towards soldering of AlN ceramics with a Cu substrate by the aid of ultrasound, and the fluxless soldering method was applied. Soldering alloy type Sn-Ag-Ti was analysed, and the interactions between the solder and ceramic and/or Cu substrate were studied. The shear strength of fabricated soldered joints was measured.
Optimum two-plane balancing of rigid rotor using discrete optimization algorithm
Authors: Singh Prem , Chaudhary Himanshu 
Published: April 2019

Purpose
This paper aims to present the optimum two-plane discrete balancing procedure for rigid rotor. The discrete two-plane balancing in which rotor is balanced to minimize the residual effects or the reactions on the bearing supports using discrete parameters such as masses and their angular positions on two balancing planes.

Design/methodology/approach
Therefore as a multi-objective optimization problem is formulated by considering reaction forces on the bearing supports as a multi objective functions and discrete parameters on each balancing plane as design variables. These multi-objective functions are converted into a single-objective function using appropriate weighting factors. Further, this optimization problem is solved using discrete optimization algorithm, based on Jaya algorithm.

Findings
The performance of the discrete Jaya algorithm is compared to genetic algorithm (GA) algorithm. It is found that Jaya algorithm is computationally more efficient than GA algorithm. A number of masses per plane are used to balance the rotor. A comparison of reaction forces using number of masses per plane is investigated.

Originality/value
The effectiveness of the proposed methodology is tested by the balancing problem of rotor available in the literature. The influence of a number of balance masses on bearing forces and objective function are discussed. ADAMS software is used for validation of a developed balancing approach.

AbstractA case of severe fever with thrombocytopenia syndrome (SFTS) in which a skin biopsy from the tick‐bite region was analyzed is reported. The patient was a 72‐year‐old woman who developed fever and thrombocytopenia after a tick bite. SFTS was diagnosed from polymerase chain reaction (PCR) analysis of a blood sample. Histopathological analysis of a skin biopsy specimen from the tick‐bite region showed CD20‐positive perivascular and interstitial immunoblastic cells, which were positive to anti‐SFTS virus (SFTSV) nucleoprotein antibody. In addition, SFTSV RNA was detected by real‐time PCR from this biopsy specimen. Moreover, hemophagocytosis was also found in the tick‐bite region. To the best of our knowledge, this is the first report to analyze the details of the tick‐bite region of skin in SFTS, and the first to detect virus‐infected cells in the skin. The present findings may help elucidate the mechanisms of entry of SFTSV.
Nitric oxide modulates μ‐opioid receptor function in vitro

Published: April 2019

AbstractPainful diabetic neuropathy (PDN) is a type of peripheral neuropathic pain that develops as a consequence of prolonged hyperglycaemia‐induced injury to the long nerves. Apart from pain,PDNis also characterized by morphine hyposensitivity. Intriguingly, in streptozotocin (STZ)‐induced diabetic rats exhibiting marked morphine hyposensitivity, dietary administration of the nitric oxide (NO) precursor, L‐arginine at 1 g/d, progressively rescued morphine efficacy and potency over an 8‐week treatment period. In earlier work, single bolus doses of the furoxan nitric oxide (NO) donor,PRG150 (3‐methylfuroxan‐4‐carbaldehyde), evoked dose‐dependent pain relief inSTZ‐diabetic rats but the efficacious doses were 3‐4 orders of magnitude higher in advanced diabetes than that required in earlySTZdiabetes. Together, these findings suggested a role forNOin the modulation of μ‐opioid (MOP) receptor signalling. Therefore, the present study was designed to assess a role forNOreleased fromPRG150, in modulatingMOPreceptor function in vitro. Here, we show an absolute requirement for theMOPreceptor, but not the δ‐opioid (DOP) or the κ‐opioid (KOP) receptor, to transduce the cellular effects ofPRG150 on forskolin‐stimulatedcAMPresponses in vitro.PRG150 did not interact with the classical naloxone‐sensitive binding site of theMOPreceptor, and its effects oncAMPresponses inHEK‐MOPcells were also naloxone‐insensitive. Nevertheless, the inhibitory effects ofPRG150 on forskolin‐stimulatedcAMPresponses inHEK‐MOPcells were dependent upon pertussis toxin (PTX)‐sensitive Gi/oproteins as well as membrane lipid rafts and src kinase. Together, our findings implicate a role forNOin modulatingMOPreceptor function in vivo.
Expressing Uncertainty in Dental Age Estimation: A Comparison between Two Methods of Calculating the “Average” Standard Deviation
Authors: Draft Derek , Lucas Victoria S. , McDonald Fraser , Andiappan Manoharan , Roberts Graham 
Published: April 2019

AbstractThe expression of uncertainty is defined by the standard deviation and is usually expressed in multiples of the standard deviation (±1sd, ±2sd, and ±3sd). The objective was to use weighting of the sd calculation by the number or count of subjects for each tooth development stage. A comparison shows the difference between the range of uncertainty using the unweighted sd and the weighted sd. The range of uncertainty related to Dental Age Estimation is statistically significantly greater (p < 0.001) for the weighted sd compared to the unweighted sd. It is concluded that the number of subjects for each Tooth Development Stage in the Reference Data set should be included in the calculation for a single Dental Age Estimation using the Simple Average Method when presenting the uncertainty associated with the point estimate of the “mean” for Dental Age Estimation of a single subject of unknown age.

AbstractSpecies trees have traditionally been inferred from a few selected markers, and genome‐wide investigations remain largely restricted to model organisms or small groups of species for which sampling of fresh material is available, leaving out most of the existing and historical species diversity. The genomes of an increasing number of species, including specimens extracted from natural history collections, are being sequenced at low depth. While these data sets are widely used to analyse organelle genomes, the nuclear fraction is generally ignored. Here we evaluate different reference‐based methods to infer phylogenies of large taxonomic groups from such data sets. Using the example of the Oleeae tribe, a worldwide‐distributed group, we build phylogenies based on single nucleotide polymorphisms (SNPs) obtained using two reference genomes (the olive and ash trees). The inferred phylogenies are overall congruent, yet present differences that might reflect the effect of distance to the reference on the amount of missing data. To limit this issue, genome complexity was reduced by using pairs of orthologous coding sequences as the reference, thus allowing us to combine SNPs obtained using two distinct references. Concatenated and coalescence trees based on these combined SNPs suggest events of incomplete lineage sorting and/or hybridization during the diversification of this large phylogenetic group. Our results show that genome‐wide phylogenetic trees can be inferred from low‐depth sequence data sets for eukaryote groups with complex genomes, and histories of reticulate evolution. This opens new avenues for large‐scale phylogenomics and biogeographical analyses covering both the extant and the historical diversity stored in museum collections.

Published: April 2019

AbstractBackgroundHigh‐mobility group box‐1 (HMGB1) acts as a damage‐associated molecular pattern or as an alarmin and it stimulates inflammatory and immunological activities.AimWe sought to investigate serum HMGB1 protein expression in patients with pediatric systemic lupus erythematosus (pSLE) in relation to the disease characteristics and activity.Patients and methodsThis is a controlled cross‐sectional study which comprised 50 children and adolescents with Systemic lupus erythematosus (SLE) and 50 age‐ and sex‐matched healthy subjects who served as a control group. Study measurements included clinical assessment, laboratory workup for SLE (complete blood count, erythrocyte sedimentation rate, serum creatinine, creatinine clearance and 24‐hour urinary protein, C3 and anti‐double‐stranded DNA, lupus anticoagulant and anticardiolipin antibodies) and measurement of serum HMGB1 by enzyme‐linked immunosorbent assay in patients and controls.ResultsSerum HMGB1 expression was significantly higher in the pSLE patients than the control group (P < 0.001). Patients with lupus nephritis (LN) had significantly higher serum HMGB1 as compared to those with normal kidneys (P < 0.04). Serum HMGB1 in LN patients correlated positively to the SLE Disease Activity Index (P < 0.0001), and 24 hours urinary proteins and negatively to creatinine clearance (P < 0.001). At a cut‐off point of ≥40 µg/L, serum HMGB1 showed good diagnostic value for pSLE with sensitivity and specificity of 98% and 95%, respectively.ConclusionSerum HMGB1 seems to be a reliable biomarker for diagnosis of pSLE and monitoring disease status, especially in LN. HMBG1 might prove to be a potential therapeutic target in LN.

AbstractBackground/ObjectivesHigh a naevus counts and atypical naevi are risk factors for cutaneous melanoma. However, many individuals with a high‐risk naevus phenotype do not develop melanoma. In this study, we describe the clinical and dermoscopic attributes of naevi associated with melanoma in a high‐risk naevus phenotype population.MethodsThis single‐centre, hospital‐based case–control study included 54 prospectively enrolled adult patients ≥18 years old with a high‐risk naevus phenotype (18 cases with a history of melanoma and 36 age‐ and gender‐matched controls without a history of melanoma). We analysed clinical and dermoscopic images of the 20 largest naevi for each participant.ResultsCases had a higher mean age than controls (48.2 vs. 39.1 years, P = 0.007) but there was no difference in the male‐to‐female ratio between groups. Nearly, all participants (97%) were Fitzpatrick skin type II or III. Naevi in cases were more likely to be truncal, (72.6% vs. 53.6%, P = 0.01), particularly anterior truncal, (29.2% vs. 14.4%, P < 0.001) and larger than 8 mm (17.4% vs. 7.8%%, P = 0.01) compared to controls. CASH score of naevi did not differ between groups. Naevi in cases were more likely to have a multicomponent dermoscopic pattern than in controls (18.4% vs. 12.6%, P = 0.02).ConclusionLarger naevi, truncal naevi, and naevi, with a multicomponent dermoscopic pattern may be risk factors for melanoma among individuals with a high‐risk naevus phenotype. Further studies are needed to validate these findings.

AbstractBackgroundActivated eosinophils cause major pathology in stable and exacerbating asthma; however, they can also display protective properties like an extracellular antiviral activity. Initial murine studies led us to further explore a potential intracellular antiviral activity by eosinophils.MethodsTo follow eosinophil‐virus interaction, respiratory syncytial virus (RSV) and influenza virus were labeled with a fluorescent lipophilic dye (DiD). Interactions with eosinophils were visualized by confocal microscopy, electron microscopy, and flow cytometry. Eosinophil activation was assessed by both flow cytometry and ELISA. In a separate study, eosinophils were depleted in asthma patients using anti‐IL‐5 (mepolizumab), followed by a challenge with rhinovirus‐16 (RV16).ResultsDiD‐RSV and DiD‐influenza rapidly adhered to human eosinophils and were internalized and inactivated (95% in ≤ 2 hours) as reflected by a reduced replication in epithelial cells. The capacity of eosinophils to capture virus was reduced up to 75% with increasing severity of asthma. Eosinophils were activated by virus in vitro and in vivo. In vivo this correlated with virus‐induced loss of asthma control.ConclusionsThis previously unrecognized and in asthma attenuated antiviral property provides a new perspective to eosinophils in asthma. This is indicative of an imbalance between protective and cytotoxic properties by eosinophils that may underlie asthma exacerbations.
