Sexual imprinting overrides order effects
Authors: Moreira Luis , Zinck Léa , Nomoto Kensaku , Lima Susana Q. 
Published: November 2019

ABSTRACTMate choice is a complex decision that requires the integration of cues from potential mates with individual preferences. Choosers’ preferences are shaped by recent events, early life experience and by the evolutionary history of its own species. To better understand the interaction between these factors, we studied mate choice in the female house mouse, Mus musculus. Females of one of the musculus subspecies, Mus musculus musculus, show preference for males of their own subspecies compared to males of the sibling subspecies, Mus musculus domesticus. Such an assortative preference is ecologically relevant at contact zones, where it contributes to the reproductive isolation of sympatric populations and can be reproduced in controlled laboratory conditions, but its origins are still under debate. Here, we show that female mouse mate choice depends on both early postnatal life experience and the order of prospective mates encountered as an adult and that these effects interact asymmetrically. Whereas females raised in their normal M. m. musculus environment display a robust assortative preference, females fostered in a M. m. domesticus family prefer the first male encountered, regardless of subspecies. Thus, early life experience of M. m. musculus females, when concordant with genetic self-identity, overrides sampling order effects, ensuring robust assortative choice. In the absence of this match between phylogeny and early life experience, first impression effects dominate mate choice.

Authors: Gunasekar P. , Manigandan S. , S. Venkatesh , Gokulnath R. , Vimal Rakesh , Boomadevi P. 
Published: November 2019

Purpose
The depletion of fossil fuel and emissions of harmful gases forced the pioneers in search of alternate energy source. The purpose of this study is to present an effective use of hydrogen fuel for turbojet engines based on its exergetic performance.

Design/methodology/approach
This study was performed to measure the assessment of exergetic data of turbojet engines. Initially, the test was carried out on the Jet A-1 fuel. Then, a series of similar tests were carried out on turbojet engines with hydrogen fuel to measure their performance results. Finally, the exergetic values of both were compared with each other.

Findings
The introduction of hydrogen fuel reduced the exergy efficiency, and a 10 per cent reduction was observed in exergy efficiency. Simultaneously, the waste exergy rate increased by 9 per cent. However, because of the high specific fuel exergy, hydrogen fuel was better than Jet A-1 fuel. Note that parameters such as environmental effect factor and ecological effect witnessed an increase in their index owing to the addition of hydrogen.

Practical implications
Introduction of alternative blends is necessary for achieving lower emission of gases such as CO, NOx and CO2 from gas turbine engines without compromising on performance. The Jet A fuels were replaced by blends to obtain better emission characteristics.

Originality/value
The use of hydrogen in turbojet engines showed an adverse effect on exergetic performance. However, it was very impressive to see a 200 per cent reduction in emissions. From the comparison of exergy efficiency results of inlet, combustion and nozzle, it is evident that the combustion chamber has the largest values of exergy ratio, waste exergy ratio, cost flow, ecological factor, environmental factor and fuel ratio owing to irreversibility in the combustion process.
The mediating role of career resilience on the relationship between career competency and career success
Authors: Ahmad Bilal , Latif Shahid , Bilal Ahmad Raza , Hai Mahnoor 
Published: November 2019

PurposeThe purpose of this paper is to empirically investigate the relationships between career competency, career resilience and career success. The study further examines the mediating role of career resilience on the relationship between career competency and career success.Design/methodology/approachData were collected from 284 Islamic bank employees across Pakistan through a cross-sectional, self-reporting, online questionnaire. Partial least squares structural equation modeling was used to test the proposed hypotheses using Smart PLS version 3.0.FindingsThe study’s results indicate that career competency is a significant predictor of career resilience, and that career resilience is subsequently a significant predictor of career success. Further, the results of the structural equation model analyses supported the proposition that career resilience mediates the relationship between career competency and career success.Practical implicationsHuman resource practitioners and managers can increase the likelihood of their employees’ career resilience by focusing on developing career-related competencies – an antecedent of career success.Originality/valueThe study clarifies prevailing misconceptions that assume a direct linear relationship between career competency and career success by establishing, through empirical evidence, that success is not an ultimate outcome of competence. In addition, it proposes an oversimplified model of the competence–resilience–success relationship.
Firm-level agreements, employment strategies and temporary workers
Authors: Minardi Saverio 
Published: November 2019

PurposeThe purpose of this paper is to investigate the impact of two-tier firm-level collective agreements on firms’ propensity to use temporary employment, accounting for the process of self-selection of firms into different bargaining levels in the Italian context. It further examines which firm-level characteristics drive this process of selection.Design/methodology/approachThe empirical analysis uses a panel data set of Italian firms for the years 2005, 2007, 2010 and 2015. Estimations are produced and compared through ordinary least square regression, random-effects and fixed-effects models.FindingsResults show that enterprises adopting two-tier firm-level agreements (TTFA) are associated with lower levels of temporary workers. However, a longitudinal analysis suggests that introducing a TTFA does not impact firms’ propensity to employ temporary workers. This novel finding highlights the presence of a selection process based on firm-level time-constant characteristics. The paper argues that these characteristics refer to management orientation toward high-road rather than low-road employment strategies. Further evidence is brought in support of this claim, showing that firms’ propensity toward the provision of training for their labor force partially explain the process of selection.Originality/valueThe study is the first to analyze the impact of secondary-level collective agreements on firms’ reliance on temporary employment, offering new evidence on the causes of the expansion of temporary employment. It further highlights the relevance of employers’ strategies in shaping the impact of the bargaining structure.
The nexus of corporate social responsibility (CSR), affective commitment and organisational citizenship behaviour in academia
Authors: Ahmad Rashid , Ahmad Saima , Islam Talat , Kaleem Ahmad 
Published: November 2019

PurposeThe purpose of this paper is to advance knowledge on the implications of perceived corporate social responsibility (CSR) on employee levels of commitment and citizenship behaviour (OCB) by investigating a trust-based mediational process in the context of academia.Design/methodology/approachThe research data are collected from a sample of 736 academics through a questionnaire based survey administered in different Pakistani universities. The nature of trust-based mechanism underlying the relationships between CSR, affective commitment and OCB is determined through structural equation modelling of the research data.FindingsThe findings suggest that the perceived CSR is an important predictor of academics’ attitudes and behaviour in universities. Whilst the findings implicate the mediating role of trust in the process by which perceived CSR influences academics’ commitment, trust does not appear to mediate the perceived CSR’s relationship with OCB.Research limitations/implicationsThis study utilises single-sourced and cross-sectional data, which may have resulted in common method bias.Practical implicationsBy furnishing evidence of the beneficial effects of perceived CSR on academics’ levels of trust, commitment and citizenship behaviour, this study provides a business case for universities’ involvement in CSR. The findings are particularly useful to academic administrators and managers who are interested in nurturing positive attitudes and behaviours amongst academic staff.Originality/valueThere is a paucity of research on CSR in the academic work settings of developing countries. This is the first study to examine the trust-based microfoundation of CSR in the context of academia in Pakistan.
The relationship between entrepreneurial intent, gender and personality
Authors: Zisser Mackenzie R. , Johnson Sheri L. , Freeman Michael A. , Staudenmaier Paige J. 
Published: November 2019

Purpose
The purpose of this study is to examine gender differences in personality traits of people with and without entrepreneurial intent to assess whether women who intend to become entrepreneurs exhibit particular tendencies that can be fostered.

Design/methodology/approach
Participants completed an online battery of well-established questionnaires to cover a range of personality traits relevant to entrepreneurship and gender. Participants also answered items concerning intent to become an entrepreneur. A factor analysis of personality traits produced four factors (esteem and power, ambition, risk propensity and communal tendency, the latter reflecting openness and cooperation, without hubris). The authors constructed four parallel regression models to examine how gender, entrepreneurial intent and the interaction of gender with intent related to these four personality factor scores.

Findings
Participants who endorsed a desire to become an entrepreneur reported higher ambition. Women with entrepreneurial intentions endorsed higher levels of communal tendency than men with entrepreneurial intent. Those without entrepreneurial intent did not show gender differences in communal tendency.

Research limitations/implications
Current findings suggest that men and women who intend to become entrepreneurs share many traits, but women with entrepreneurial intent show unique elevations in communal tendencies. Thus, a worthwhile locus for intervention into the gender disparity in self-employment would be providing space and acknowledgement of prosocial motivation and goals as one highly successful route to entrepreneurship.

Originality/value
Given the underused economic potential of women entrepreneurs, there is a fundamental need for a rich array of research on factors that limit and promote women’s entry into entrepreneurship. Current findings indicate that personality may be one piece of this puzzle.
Applying innovation attributes to predict purchase intention for the eco-labeled products
Authors: Hosseinikhah Choshaly Sahar 
Published: November 2019

Purpose
This paper aims to make use of the innovation diffusion theory to predict the purchase intention for eco-labeled products.

Design/methodology/approach
Data are collected from 180 individuals in the Mid Valley shopping mall area in Malaysia. It is then analyzed using SPSS and Smart PLS. The measurement model is analyzed using composite reliability, convergent and discriminate validity, while the structural model is used to predict the relationships between variables.

Findings
Results indicate that the relative advantage, trialability and observability are positively related to eco-labeled products purchase intention, while the complexity is negatively related to eco-labeled products purchase intention. However, compatibility is not positively related to eco-labeled products purchase intention.

Practical implications
Marketers should enhance the observability of eco-labeled as it is the most influential attribute affecting eco-labeled products purchase intention. Relative advantages of eco-labeled products are also important to stimulate purchase intention. Marketers could best relate the innovation to context-specific use situations enabling consumers to evaluate the use consequences of the innovation, and therefore, may assess its particular benefits.

Originality/value
It explores the potential of a theoretical framework based on innovation diffusion theory to explain eco-labeled products purchase intention.
How open is OpenGLAM? Identifying barriers to commercial and non-commercial reuse of digitised art images
Authors: Valeonti Foteini , Terras Melissa , Hudson-Smith Andrew 
Published: November 2019

Purpose
In recent years, OpenGLAM and the broader open license movement have been gaining momentum in the cultural heritage sector. The purpose of this paper is to examine OpenGLAM from the perspective of end users, identifying barriers for commercial and non-commercial reuse of openly licensed art images.

Design/methodology/approach
Following a review of the literature, the authors scope out how end users can discover institutions participating in OpenGLAM, and use case studies to examine the process they must follow to find, obtain and reuse openly licensed images from three art museums.

Findings
Academic literature has so far focussed on examining the risks and benefits of participation from an institutional perspective, with little done to assess OpenGLAM from the end users’ standpoint. The authors reveal that end users have to overcome a series of barriers to find, obtain and reuse open images. The three main barriers relate to image quality, image tracking and the difficulty of distinguishing open images from those that are bound by copyright.

Research limitations/implications
This study focusses solely on the examination of art museums and galleries. Libraries, archives and also other types of OpenGLAM museums (e.g. archaeological) stretch beyond the scope of this paper.

Practical implications
The authors identify practical barriers of commercial and non-commercial reuse of open images, outlining areas of improvement for participant institutions.

Originality/value
The authors contribute to the understudied field of research examining OpenGLAM from the end users’ perspective, outlining recommendations for end users, as well as for museums and galleries.
Exploring pornography use in secure hospitals: a qualitative analysis
Authors: Mellor Emily , Duff Simon 
Published: November 2019

Purpose
This research paper reports findings from a qualitative analysis which explored pornography use in secure hospitals. The purpose of this paper is to investigate what attitudes staff working in secure hospital have towards patients having access to pornography, how they make decisions regarding access to pornography and what factors they take into account during this process. This research is an extension of a prior quantitative research study (Mellor and Duff, 2019).

Design/methodology/approach
The study utilised a qualitative approach using semi-structured interviews to explore professionals’ attitudes towards pornography use in a secure hospital. The sample comprised of six volunteers who had taken part in a previous research study (Mellor and Duff, 2019) requesting to discuss the topic area further. As such this research study was developed. Thematic analysis (Braun and Clarke, 2006) was used to analyse the qualitative data and the Attitudes towards Pornography Scale (Evans-DeCicco and Cowan, 2001) was used to collect demographic information.

Findings
Six themes were identified from the transcripts. The first theme explores staff members’ attitudes towards pornography. The second relates to the use of boundaries and monitoring of pornography. The third theme looks at the potential impact that pornography could have on the patient, either positive or negative. The fourth theme explores the extent to which patients are still considered as human beings, whereas the fifth theme explores the vulnerabilities that may make patients more at risk of being negatively influenced by pornography. The final theme looks at decision making regarding access to pornography.

Practical implications
The research offers an insight into how pornography within secure hospitals is managed. The research also provides an exploration into multi-disciplinary team decision making with regard to pornographic material and notes the general openness of staff towards patients having access to pornography.

Originality/value
The findings have important messages for services with regard to policy making. The findings are also relevant for understanding how pornography is managed with in secure hospitals.
Impact of intellectual capital on productivity of insurance companies in Ghana
Authors: Oppong Godfred Kesse , Pattanayak Jamini Kanta , Irfan Mohd. 
Published: November 2019

Purpose
The purpose of this paper is to empirically investigate the effect of intellectual capital (IC) efficiency on changes in the productivity of insurance companies in Ghana.

Design/methodology/approach
Using a panel of 33 insurance companies from 2008 to 2016, the study applied Value Added Intellectual Coefficients model as a measure of IC efficiency, whilst Malmquist Productivity Index is employed to capture changes in the productivity of insurance companies. In estimating the effects of IC on productivity, System Generalised Method of Moment (GMM) is applied because of its power over endogeneity and heteroscedasticity.

Findings
Robust empirical findings on productivity analysis showed that improvements in insurer’s productivity were experienced in three year intervals out of the overall studied year. In addition, panel regression results revealed that IC along with human capital and capital employed significantly affect the productivity of insurance companies.

Research limitations/implications
The generalisability of the study findings could be questioned because it is limited to insurance firms operating in Ghana; some firms were omitted due to mergers and acquisition that reduced the final sample. Yet, the findings facilitate the validation of IC concept and, hence, informs manager/policy makers on IC utilisation as a source of competitive edge.

Practical implications
Having robust empirical findings, the study expands on the existing literature by unveiling the dynamic nature of IC relationship and productivity. The findings also serve as a benchmark for managers/policymakers in insurance companies to increase the operational efficiency by investing in IC, which will help guarantee improve returns on generated premiums.

Originality/value
Although a few studies have investigated the effect of IC in Ghana, this study is the first to examine the dynamic relationship between IC and changes in productivity in a Ghanaian context.

Purpose
The purpose of this paper is to build a case for globally diversified core real estate funds portfolio.

Design/methodology/approach
It uses Monte Carlo simulation technique to construct synthetic real estate funds portfolios.

Findings
Benefit of maintaining globally diversified real estate funds portfolio merits admission. An optimal portfolio has an almost even split between Europe, USA and Asia Pacific, ceteris paribus. Likewise, currency effect for Europe domiciled investors is undeniable.

Practical implications
The overall estimates suggest that a blend of APAC, European and US allocations enhance portfolio risk return profile.

Originality/value
The study adds additional evidence on the contested issue of real estate diversification.

Authors: Wanyan Dengdeng , Hu Jiahao 
Published: November 2019

Purpose
The purpose of this paper is to understand the consumption and demand of Chinese citizens for public digital culture, and make suggestions for government-supported public digital culture providers.

Design/methodology/approach
Through a questionnaire survey, this study investigates the provision of public digital cultural services (PDCS) from the perspective of consumption and demands.

Findings
The results indicate: the Chinese populace as a whole had low expenses on digital cultural services, and had not effectively utilized them to support their own development; significant disparities exist between demographics, particularly between urban and rural residents; the populace were strongly interested in participation in public digital culture, but the services had low actual utilization rates; and the services had been unable to meet the users’ quality-related demands.

Originality/value
The first study to approach the provision of PDCS from the side of consumption and user demand.
Risk factors for recurrence in cutaneous squamous cell carcinoma after Mohs micrographic surgery: A retrospective review of 237 Asian patients
Authors: Oh Yeongjoo , Kim Jemin , Zheng Zhenlong , Kim Sang Kyem , Chung Kee Yang , Roh Mi Ryung 
Published: November 2019

AbstractEven after complete removal with Mohs micrographic surgery (MMS), cutaneous squamous cell carcinoma (cSCC) may recur; however, information about risk factors for recurrence in Asian patients is limited. This retrospective study reviewed cSCC patients treated with MMS at a single tertiary referral center from 2000 to 2017. Two hundred and thirty‐seven patients were included and 36 showed recurrence (20 with local recurrence, 16 with distant metastasis). History of organ transplantation, diabetes, other malignancies and poorly differentiated histology correlated with cSCC recurrence. History of organ transplantation and cryotherapy at the cSCC site were related to higher local recurrence rates, and poor differentiation related to higher distant metastasis in Asian cSCC patients treated with MMS.
A clockwork fish: Age prediction using DNA methylation‐based biomarkers in the European seabass
Authors: Anastasiadi Dafni , Piferrer Francesc 
Published: November 2019

AbstractAge‐related changes in DNA methylation do occur. Taking advantage of this, mammalian and avian epigenetic clocks have been constructed to predict age. In fish, studies on age‐related DNA methylation changes are scarce and no epigenetic clocks have been constructed. However, in fisheries and population dynamics studies there is a need for accurate estimation of age, something that is often impossible for some economically important species with the currently available methods. Here, we used the European sea bass, a marine fish the age of which can be determined with accuracy, to construct a piscine epigenetic clock, the first one in a cold‐blooded vertebrate. We used targeted bisulfite sequencing to amplify 48 CpGs from four genes in muscle samples and applied penalized regressions to predict age. We thus developed an age predictor in fish that is highly accurate (0.824) and precise (2.149 years). In juvenile fish, accelerated growth due to elevated temperatures had no effect on age prediction, indicating that the clock is able to predict the chronological age independently of environmentally‐driven perturbations. An epigenetic clock developed using muscle samples accurately predicted age in samples of testis but not ovaries, possibly reflecting the reproductive biology of fish. In conclusion, we report the development of the first piscine epigenetic clock, paving the way for similar studies in other species. Piscine epigenetic clocks should be of great utility for fisheries management and conservation purposes, where age determination is of crucial importance.
