Intranasal oxytocin enhances approach-related EEG frontal alpha asymmetry during engagement of direct eye contact
Authors: Soriano Javier R. , Daniels Nicky , Prinsen Jellina , Alaerts Kaat 
Published: February 2020

AbstractThe neuropeptide oxytocin is suggested to exert a pivotal role in a variety of complex human behaviors, including interpersonal bonding, trust, and attachment. Recent theories have suggested that the role oxytocin plays in these complex social behaviors involves a modulation of motivational tendencies of approach/avoidance-related behaviors. However, to date, direct neurophysiological evidence supporting this notion is limited. In this double-blind, randomized, placebo-controlled study with parallel design, we assessed the effects of administered intranasal oxytocin in 40 adult men on gaze behavior and a neural marker of approach/avoidance motivational tendencies. Specifically, electroencephalography recordings were performed during the engagement of eye contact with a live model in a naturalistic two-person social context and electroencephalographic frontal alpha asymmetry, an established neurophysiological index of motivational tendencies for approach/avoidance-related behaviors, was assessed. Compared to placebo, a single dose of oxytocin (24 international units) was shown to increase relative left-sided frontal asymmetry upon direct eye contact with a live model, which is indicative of an increase in approach-related motivational tendencies toward the presented eye contact stimulus. Notably, the treatment effect was most prominently observed in participants with lower self-reported social motivation (higher Motivation subscale scores on the Social Responsiveness Scale), indicating that participants with lower social motivation benefitted the most from the administered oxytocin. No treatment-specific changes were identified in terms of gaze behavior toward the eye region of the live model. Together, these observations add neurophysiological evidence to the hypothesized role of oxytocin in modulating approach/avoidance related tendencies and suggest that inter-individual variance in person-dependent factors need to be considered in order to evaluate the potential benefit of intranasal oxytocin as a treatment. This notion is of particular relevance to the variety of neuropsychiatric populations such as autism spectrum disorder, social anxiety disorder and depression, for which intranasal oxytocin is increasingly considered a potential treatment.
Appraisal on corrosion performances of CrNi, TiAlN/CrNi and CrNi–Al2O3–TiO2 coatings on H13 hot work mold
Authors: Dejun Kong , Jiahong Li 
Published: February 2020

Purpose
The purpose of this paper is to evaluate the salt spray corrosion (SSC) and electrochemical corrosion performances of CrNi, TiAlN/NiCr and CrNi–Al2O3–TiO2 coatings on H13 steel, which improved the corrosion resistance of H13 hot work mold.

Design/methodology/approach
CrNi, TiAlN/NiCr and CrNi–Al2O3–TiO2 coatings were fabricated on H13 hot work mold steel using a laser cladding and cathodic arc ion plating. The SSC and electrochemical performances of obtained coatings were investigated using a corrosion test chamber and electrochemical workstation, respectively. The corrosion morphologies, microstructure and phases were analyzed using an electron scanning microscope, optical microscope and X-ray diffraction, respectively, and the mechanisms of corrosion resistance were also discussed.

Findings
The CrNi coating is penetrated by corrosion media, producing the oxide of Fe3O4 on the coating surface; and the TiAlN coating is corroded to enter into the CrNi coating, forming the oxides of TiO and NiO, the mechanism is pitting corrosion, whereas the CrNi–Al2O3–TiO2 coating is not penetrated, with no oxides, showing the highest SSC resistance among the three kinds of coatings. The corrosion potential of CrNi coating, TiAlN/CrNi and CrNi–Al2O3–TiO2 coatings was –0.444, –0.481 and –0.334 V, respectively, and the corresponding polarization resistances were 3,074, 2,425 and 86,648 cm2, respectively. The electrochemical corrosion resistance of CrNi–Al2O3–TiO2 coating is the highest, which is enhanced by the additions of Al2O3 and TiO2.

Originality/value
The CrNi, TiAlN/CrNi and CrNi–Al2O3–TiO2 coatings on H13 hot work mold were firstly evaluated by the SSC and electrochemical performances.
Ultra-low-power time-efficient circuitry of dual comparator/amplifier for SAR ADC by CMOS technology
Authors: Faheem Muhammad Yasir , Zhong Shun'an , Wang Xinghua , Azeem Muhammad Basit 
Published: February 2020

Purpose
Successive approximation register (SAR) analogue to digital converter (ADC) is well-known with regard to low-power operations. To make it energy-efficient and time-efficient, scientists are working for the last two decades, and it still needs the attention of the researchers. In actual work, there is no mechanism and circuitry for the production of two simultaneous comparator outputs in SAR ADC.

Design/methodology/approach
A small-sized, low-power and energy-efficient circuitry of a dual comparator and an amplifier is presented, which is the most important part of SAR ADC. The main idea is to design a multi-dimensional circuit which can deliver two quick parallel comparisons. The circuitry of the three devices is combined and miniaturized by introducing a lower number of MOSFET’s and small-sized capacitors in such a way that there is no need for any matching and calibration.

Findings
The supply voltage of the proposed comparator is 0.7 V with the overall power consumption of 0.257mW. The input and clock frequencies are 5 and 50 MHz, respectively. There is no requirement for any offset calibration and mismatching concerns due to sharing and centralization of spider-latch circuitry. The total offset voltages are 0.13 0.31 mV with 0.3VDD to VDD. All the components are small-sized and miniaturized to make the circuit cost-effective and energy-efficient. The rise and response time of comparator is around 100 ns. SNDR improved from 56 to 65 dB where the input-referred noise of an amplifier is 98mVrms.

Originality/value
The proposed design has no linear-complexity compared with the conventional comparator in both modes (working and standby); it is ultimately intended and designed for 11-bit SAR ADC. The circuit based on three rapid clock pulses for three different modes includes amplification and two parallel comparisons controlled and switched by a latch named as “spider-latch”.
The role of the media in socially responsible investing
Authors: Lei Shan , Zhang Yafei 
Published: February 2020

PurposeThis study aims to understand how media content and media sentiment in corporate social responsibility (CSR) news coverage affect investment performance, as reflected in the S&P 500 Environmental and Socially Responsible Index from 2010 to 2016.Design/methodology/approachComputer-assisted content analysis and sentiment analysis are employed to analyze 818 CSR-related newspaper articles from mainstream newspapers. Autoregressive model is used to comprehend socially responsible investment (SRI) performance.FindingsThis study reveals the impact of media content and media sentiment of CSR-related news articles on SRI. The authors’ findings indicate that such topics as recognition of a company's CSR contributions in CSR-related news articles are positively associated with SRI performance, whereas topics such as tax avoidance and environmental protection show a negative relationship with SRI performance. In addition, this study contributes to the authors’ understanding of framing bias in investment by confirming a significant positive association between an uncertain or constraining media sentiment and SRI performance, as well as a negative relationship between a litigious sentiment and SRI performance.Originality/valueThere has been limited attention to examining the effect of media coverage of CSR on the financial market. Since SRI is one of the most useful financial indices for SRIs, it is meaningful to explore the relationship between media coverage of CSR and SRI. To fill the research gap, this study specifically examines how media coverage of CSR-related issues is associated with SRI performance.
Sustainability coursework: student perspectives and reflections on design thinking
Authors: Clark Renee M. , Stabryla Lisa M. , Gilbertson Leanne M. 
Published: February 2020

Purpose
The purpose of this study was to assess particular student outcomes when design thinking was integrated into an environmental engineering course. The literature is increasingly promoting design thinking for addressing societal and environmental sustainability engineering challenges. Design thinking is a human-centered approach that identifies needs upfront.

Design/methodology/approach
In an undergraduate engineering course, Design for the Environment, students have begun to obtain hands-on experience in applying design thinking to sustainability challenges. This case study investigates the association between the use of design thinking and student creativity with sustainability design solutions. Student perspectives on their own creativity and future sustainable design practices as a result of the course were also investigated.

Findings
The findings were favorable for design thinking, being associated with a significant difference and medium-to-large effect with regards to solution novelty. A qualitative analysis showed a positive association between design thinking and students’ perceptions of their creativity and future anticipated sustainability practices. Using a content analysis of reflective writings, students’ application of design thinking was assessed for comprehensiveness and correctness. A two-week introductory design-thinking module and significant use of in-class active learning were the course elements that most notably impacted students’ use of design thinking.

Practical implications
This case study preliminarily demonstrates that application of design thinking within an environmental engineering course may be associated with beneficial outcomes related to creativity and sustainability.

Originality/value
A review of the literature did not uncover studies of the use of design thinking for undergraduate socio-environmental challenges to promote creativity and sustainable-practices outcomes, although the literature has been calling for the marrying of these two areas.

Authors: Du Cros Hilary , Kong Weng Hang 
Published: February 2020

Purpose
The purpose of this study is to offer advice to the Macao Special Administrative Region (SAR) Government regarding the tourist and traffic flow concerning how these contribute to congestion in World Heritage Site (WHS) elements and make recommendations regarding the management of tourist flows and traffic congestion.

Design/methodology/approach
The research undertaken in this study is partially longitudinal. The case study is also partially ethnographic in that tourist behaviour at key sites has been observed. Concerning the specific methodology applied, data collection techniques are chosen to provide a multiplicity of data sources: on-site observation and semi-structured telephone interviews.

Findings
The study is found that Macao was at a crossroad. All stakeholders needed to take some responsibility for implementing actions recommended that would ensure that Macao SAR’s World Heritage assets would be used responsibly for future, as well as for present generations.

Originality/value
The study has shown that better and long-term understanding of congestion is necessary to inform better visitor management decision-making, enhance tourist experience and discover the factors that influence visitor satisfaction. It is also needed to reveal aspects of stakeholder readiness and barriers to action.

The moderating effects of transformational leadership and self-worth in the idiosyncratic deals – employee reactions relationship
Authors: Katou Anastasia , Budhwar Pawan , Chand Mohinder D. 
Published: February 2020

PurposeThis paper examines the relationship between timing of negotiations and idiosyncratic deals (i-deals) through the moderating effects of core self-evaluations (CSE), and between i-deals and employee reactions through the moderating effects of transformational leadership behaviour (TLB) in the Indian hospitality industry.Design/methodology/approachA total of 275 employees working in 39 companies responded to a self-administered questionnaire. To test the research hypotheses, the methodology of structural equation models was used.FindingsThe results show that the relationship between before hiring negotiations and i-deals is stronger for those individuals who had low self-worth, due to countervailing forces created by their belief that they may not be eligible for i-deals. In contrast, the relationship between after hiring negotiations and i-deals is stronger for those who had high self-worth, due to their belief that they were entitled to i-deals. Additionally, the research highlights that the relationship between i-deals and employee reactions is stronger for those organisations, which are high on TLB.Research limitations/implicationsThe data does not allow for investigating dynamic causal inferences, because they were collected using a questionnaire at a single point in time, and they were reported in retrospect, raising measurement concerns about recall bias.Practical implicationsFrom a managerial point of view, the findings of this study inform that in negotiating both employment conditions and work arrangements, organisations should try to achieve i-deals that are primarily flexibility focused, and that in increasing efficiency organisations should make the employees feel well supported in order to develop more confidence in deploying skills and abilities to address a more open view of their i-deals.Originality/valueThe study contributes to our understanding about the Indian hospitality industry by utilising the self-enhancement theory in examining whether individual differences moderate the relationship between the timing of negotiations and i-deals, and also by utilizing the social exchange theory to examine whether TLB moderates the relationship between i-deals and employee reactions.
Too much love will kill you: the development and function of group emotional awareness
Authors: Boroş Smaranda , Vîrgă Delia 
Published: February 2020

Purpose
This paper aims to enhance clarity for the conceptualization and measurement of group emotional awareness by defining it as an emergent state. The authors explore the emergence of this state through two studies designed to explore the four characteristics (global, radically novel, coherent and ostensive) of emergent phenomena (Waller et al., 2016).

Design/methodology/approach
In Study 1, the authors explore in an experimental setting the formation of group emotional awareness and regulation as emergent states as a result of compositional effects (team members’ self-perceptions of their individual emotional awareness capabilities) and group norms regarding emotional awareness. Study 2 uses an experimental design to explore how pre-existing expectations of group emotional awareness, based on previous dyadic interactions between team members, can prevent conflict escalation (from task to relationship conflict) in project teams.

Findings
Individual perceptions of members’ own abilities and group norms interact in the emergence of group emotional awareness. Group emotion regulation can develop only under an optimal level of emergent group emotional awareness; groups that build emotional awareness norms compensate for their members’ low awareness and develop equally efficient regulatory strategies as groups formed of emotionally aware individuals. However, the conjunction of personal propensity towards awareness and explicit awareness norms blocks the development of regulatory strategies. Group emotional awareness (both as a developed state and as an expectation) reduces the escalation of task to relationship conflict.

Originality/value
Designing for the exploration of the four characteristics of emergence allowed us to gain new insights about how group emotional awareness emerges and operates too much awareness can hurt, and affective group expectations have the power to shape reality. These findings have strong implications for practitioners’ training of emotional awareness in organizations.

Published: February 2020

BackgroundCircular RNA (circRNA) is a novel molecular marker and target candidate that is closely associated with tumor invasion and migration. The mechanism of action of hsa_circ_0005035 (circ‐IGF1R) in non‐small cell lung cancer remains unclear. In this study, we aimed to study the mechanism of action of circ‐IGF1R in lung cancer.MethodsWe screened circ‐IGF1R, one of the most notable differential expressions, from the Gene Expression Omnibus database, GSE104854, for further research. The expression level of circ‐IGF1R was examined using quantitative reverse transcription‐polymerase chain reaction (qRT‐PCR) in five different lung cancer cell lines and 50 pairs of lung cancer and adjacent tissues. Wound‐healing and Transwell assays were used for verifying the biological function of circ‐IGF1R. The effect of overexpressing circ‐IGF1R on the transcriptome of whole lung cancer cells was explored in lung cancer cell lines using RNA‐seq.ResultsThe expression level of circ‐IGF1R was notably lower in lung cancer tissues and lung cancer cell lines than in the adjacent normal tissues and cells (P < 0.0001). In addition, the expression level of circ‐IGF1R was associated with larger tumors (T2/T3/T4) and lymph node metastasis (N1/ N2/N3) (P < 0.05). The overexpression of circ‐IGF1R significantly inhibited the invasion and migration of the lung cancer cells. The potential network of circ‐IGF1R–miR‐1270–VANGL2 was preliminarily determined, and the expression patterns of miR‐1270 and VANGL2 were verified in lung cancer cell lines.ConclusionCirc‐IGF1R may inhibit lung cancer invasion and migration through a potential network of circ‐IGF1R–miR‐1270–VANGL2.

Published: February 2020

AbstractIntroductionAssisted reproduction technologies are being rapidly developed and implementation of preimplantation genetic testing (PGT) has allowed patients with genetic disorders to initiate pregnancies while minimizing or eliminating the risk of transmitting these disorders to their offspring. Testing for numeric chromosomal anomalies has been proposed as a way to increase efficacy in assisted reproduction; however, this remains disputed. Legislation is lagging behind the rapid developments in this field.Material and methodsWe conducted a structured online survey of legislation and accessibility to preimplantation genetic testing in the Nordic countries to compare the regulation and uptake of this technique. The survey was designed and answered by the authors.ResultsKey elements in the regulation of preimplantation testing for monogenic disorders and structural rearrangements are similar in the Nordic countries, although accessibility varies since only Denmark, Finland, and Sweden have national clinics offering treatment. In addition, Denmark and Finland have private clinics offering PGT. Regulation is the most stringent in Norway where a national board evaluates all couples seeking treatment. Treatment volumes vary between the Nordic countries, with Norway and Finland having lowest treatment numbers. Preimplantation genetic testing for aneuploidy in the embryo varies between the Nordic countries: Finland and Iceland allow this form of treatment, Denmark and Sweden offer it only in the form of a research protocol, and Norway does not allow it at all. Therefore the number of treatment cycles involving testing for embryo aneuploidy are lower in the Nordic countries than in other countries where this treatment option is more common.ConclusionsScience needs to inform politics regarding the rapidly evolving field of reproductive medicine and we recommend harmonization of legislation and accessibility between the Nordic countries.
