Stress–strength reliability models involving generalized gamma and Weibull distributions
Authors: Nojosa Ronald , Rathie Pushpa Narayan 
Published: March 2020

PurposeThis paper deals with the estimation of the stress–strength reliability R = P(X < Y), when X and Y follow (1) independent generalized gamma (GG) distributions with only a common shape parameter and (2) independent Weibull random variables with arbitrary scale and shape parameters and generalize the proposal from Kundu and Gupta (2006), Kundu and Raqab (2009) and Ali et al. (2012).Design/methodology/approachFirst, a closed form expression for R is derived under the conditions (1) and (2). Next, sufficient conditions are given for the convergence of the infinite series expansions used to calculate the value of R in case (2). The models GG and Weibull are fitted by maximum likelihood using Broyden–Fletcher–Goldfarb–Shanno (BFGS) quasi-Newton method. Confidence intervals and standard errors are calculated using bootstrap. For illustration purpose, two real data sets are analyzed and the results are compared with the existing recent results available in the literature.FindingsThe proposed approaches improve the estimation of the R by not using transformations in the data and flexibilize the modeling with Weibull distributions with arbitrary scale and shape parameters.Originality/valueThe proposals of the paper eliminate the misestimation of R caused by subtracting a constant value from the data (Kundu and Raqab, 2009) and treat the estimation of R in a more adequate way by using the Weibull distributions without restrictions in the parameters. The two cases covered generalize a number of distributions and unify a number of stress–strength probability P(X < Y) results available in the literature.
Work–life balance in Europe: institutional contexts and individual factors
Authors: Stoilova Rumiana , Ilieva-Trichkova Petya , Bieri Franziska 
Published: March 2020

PurposeThe purpose of this paper is to explore how individual and macro-level factors shape the work–life balance of young men and women across European countries.Design/methodology/approachThe paper combines macro-level data from the official statistics with individual-level data from the Work, Family and Wellbeing (2010/2011) module of the European Social Survey. The study uses multilevel modelling to explore the factors which shape the work–life balance of men and women aged 15–34 across 24 European countries.FindingsThe findings show both differences and similarities between young men and women in how education shapes work–life balance. Higher education increases the likelihood of considering work–life balance as important in work selection for men, while lower education decreases the odds of considering this balance for women. More education is associated with lower acceptance of the traditional norm, for both men and women, and less time spent on housework. Higher share of family benefits decreases the importance of work–life balance, more so for men than for women. Work–life balance is more important for men living in conservative, Mediterranean and post-socialist welfare regimes compared to those from social-democratic regimes.Social implicationsThe policy implications are to more closely consider education in the transformation of gender-sensitive norms during earlier stages of child socialization and to design more holistic policy measures which address the multitude of barriers individuals from poor families and ethnic/migrant background face.Originality/valueThe study contributes to existing literature by applying the capability approach to the empirical investigation of work–life balance. The analytical model contains three dimensions – norms about paid/unpaid work, considering work–life balance in the choice of employment and time spent on unpaid work. Through this approach, we are able to uncover the agency inequality of young people taking into account individual level characteristics, including gender, education, ethnicity and macro-level factors.
Impact of 3D-printing structure on the tribological properties of polymers
Authors: Hanon Muammel M. , Marczis Róbert , Zsidai László 
Published: March 2020

Purpose
The purpose of this paper is to examine the impact of three-dimensional (3D)-printing process settings (particularly print orientation) on the tribological properties of different polymers.

Design/methodology/approach
In this study, fused deposition modelling 3D-printing technology was used for fabricating the specimens. To evaluate the influence of print orientation, the test pieces were manufactured horizontally (X) and vertically (Z). The tribological properties of various printed polymers, which are polylactide acid, high tensile/high temperature-polylactide acid and polyethylene terephthalate-glycol have been studied. The tribological tests have been carried out under reciprocating sliding and dry condition.

Findings
The results show that the presence of various orientations during the 3D-printing process makes a difference in the coefficient of friction and the wear depth values. Findings suggest that printing structure in the horizontal orientation (X) assists in reducing friction and wear.

Originality/value
To date, there has been very limited research on the tribology of objects produced by 3D printing. This work was made as an attempt to pave the way for future research on the science of tribology of 3D-printed polymers.
Motivations of employees' communicative behaviors on social media
Authors: Lee Yeunjae 
Published: March 2020

PurposeGiven that an increasing number of social media platforms allow employees to share company-related information, the present study seeks to understand their complicated motivations for social media behaviors. Specifically, this study explores the antecedents of employees' positive and negative company-related information-sharing intentions on two distinctive social media platforms, personal (e.g. Facebook) and anonymous social networking sites (e.g. Glassdoor).Design/methodology/approachAn online survey was conducted with 419 full-time employees in the United States from various industry sectors.FindingsIndividual (enjoyment, venting negative feelings, and self-enhancement), interpersonal (bonding and bridging ties), and organizational (organization–employee relationship and perceived external prestige) factors are considerably and distinctly associated with employees' behavioral intentions on different social media platforms.Originality/valueThis study is among the first to understand employees' communicative behaviors on social media (sECB) by linking diverse levels of motivational factors: individual, interpersonal, and organizational using a theoretical framework of socioecological model (SEM). This study also provides significant practical guidelines for organizational leaders and platform operators by explicating the dynamics of employee motives in engaging in a variety of social media platforms.
Interconnected business models: present debates and future agenda
Authors: Jocevski Milan , Arvidsson Niklas , Ghezzi Antonio 
Published: March 2020

Purpose
The purpose of this study is to provide a review of the emergent literature to advance the current understanding of the business model (BM) concept in a context in which more than one actor is actively involved in the development and delivery of a joint offer based on information and communication technologies.

Design/methodology/approach
The paper uses a systematic literature review approach. The review is based on 25 systematically selected publications published from 2000 to 2018 and retrieved from bibliographic databases and through a process of snowballing.

Findings
The authors found several alternative conceptualizations of a BM at a network level, which highlighted different elements as core components. Based on this, authors’ findings suggest the literature has a fragmented view of what the BM concept entails at a network level, and of which actors are relevant. Conversely, there is a consensus that a single-firm view is inadequate for describing and studying joint value architectures because of its inability to consider all involved actors and their activities and resources. Therefore, a network-oriented view, as a relational aggregator, is seen as a possible way forward.

Originality/value
The study contributes to the current understanding of a BM concept at a network level and suggests three viewpoints from which to interpret value architectures at different levels of analysis: single-firm view, dyadic-level view and network-oriented view. Furthermore, the authors highlight several gaps to be studied and provide avenues for future research opportunities for scholars.
Better than sex: further development and validation of the consumption gender scale
Authors: Pohlmann Attila , Chen Qimei 
Published: March 2020

PurposeBiological sex is an important segmenting variable in marketing. Yet its ability to meaningfully distinguish beyond the female/male dichotomy is limited. With traditional gender roles continuously shifting and contemporary fluid conceptualizations of gender altering the consumption mainstream, the diverse and multi-faceted behaviours related to gender elude market segment distinctions that are based on biological sex alone. Thus far, researchers have had only limited success applying the concept of gender identity and gender schema theory to inform marketing research and management. The purpose of this study is to further develop a consumer decision-oriented scale that addresses this gap by providing a more sensitive method of segmentation.Design/methodology/approachThe scale was validated according to common psychological scale development techniques.FindingsNot only does the Consumption Gender Scale predict the behaviours and media preferences of traditional, gender-schematic male and female consumer segments, but it also accounts for the variance in the behaviours of gender-aschematic non-traditional men and women. We demonstrate the scale’s predictive power in two experimental studies and discuss its potential to serve as an intermediary variable that can predict product attitudes and purchase intentions on social media.Research limitations/implicationsThe Consumption Gender Scale was based on surveys and experiments conducted in the USA. Future research could examine the suitability of the scale in other cultural contexts.Practical implicationsThe Consumption Gender Scale provides a finer taxonomy for organizations to use in segmenting their target market on the basis of consumption-relevant gender rather than biological sex. Consequently, it also provides opportunities for managers to fine-tune their media-planning efforts.Originality/valueBiological sex as the main segmenting variable has become inadequate because of ongoing shifts in gender roles and changes in associated consumption behaviours. To address the shortcomings of traditional methods, we advocate for and validate a continuous measurement scale.
Measuring European cultural and creative cities efficiency: a metafrontier DEA approach
Authors: De Jorge-Moreno Justo , De Jorge-Huertas Virignia 
Published: March 2020

PurposeThe purpose of this paper is to conduct a benchmark analysis of European cities based on the estimation of a composite index of efficiency from the dimensions of the Cultural and Creative Cities Monitor 2017 (CCCM). The study helps to initiate a new exploration path based on this information, using a segmentation criterion of countries according to their economic and demographic characteristics, in search of greater comparative homogeneity.Design/methodology/approachIn this paper, the metafrontier methodological proposal with data envelopment analysis (DEA) has been used to compare the groups of cities individually with their joint reference.FindingsThe results obtained indicate, from a greater control of heterogeneity, through the segmentation of the sample of cities and the metafrontier methodology, that the composite index (IEC3) through the enveloping data analysis methodology (DEA) is more robust than that obtained with the arbitrary assignment of CCCM weights. The analyses carried out make it possible to study and conduct more real and rigorous comparisons of the cities that experience the best practices, unlike other more distant ones. Reference to cities such as Paris, Louvain and Cork could serve as a basis for possible improvements.Originality/valueIt is important to bear in mind that the possible urban policies of a city and the creative strategies and their derived impact are different, because of the diversity in each city. These new comparability possibilities could serve as a tool for economic policy makers, companies and local managers to carry out learning and simulation processes in the improvement of creative cities.
Towards the proposition of a Lean Automation framework
Authors: Tortorella Guilherme , Sawhney Rapinder , Jurburg Daniel , de Paula Istefani Carisio , Tlapa Diego , Thurer Matthias 
Published: March 2020

PurposeThe objective of this research is twofold. First, we aim at identifying the pairwise relationships between Lean Production (LP) practices and Industry 4.0 (I4.0) technologies. Second, based on these results, we propose a framework for Lean Automation (LA) implementation, in which I4.0 technologies are integrated into LP practices.Design/methodology/approachTo achieve that, a cross-sector survey was performed with 147 manufacturers that are undergoing a LP implementation aided by novel information and communication technologies from I4.0. Multivariate data analysis was applied in order to underpin the proposed framework for LA.FindingsFindings indicate that I4.0 technologies are positively correlated with LP practices, providing evidence to bear the proposition of a LA framework that can potentially overcome traditional barriers and challenges of a LP implementation.Originality/valueAs previous studies have approached LA implementation from a narrow perspective or including a limited set of LP practices and I4.0 technologies, the proposition of an integrated framework unfolds a wider range of synergistic implementations that may corroborate to a holistic approach for continuous improvement in the Fourth Industrial Revolution era.
A history of brand misdefinition – with corresponding implications for mismeasurement and incoherent brand theory
Authors: Gaski John F. 
Published: March 2020

Purpose
This paper aims to dissect conceptual and semantic issues surrounding the word “brand.” Theoretical, operational and practical concerns resulting from the term’s use and misuse are exposed, some derived managerial problems are highlighted, and alternatives for resolving the confusing and dysfunctional brand nomenclature are offered.

Design/methodology/approach
Comprehensive literature review, i.e. review of an entire population of literature, incorporating content analysis.

Findings
A large fraction of empirical brand literature is ambiguous because the definition, meaning and therefore measurement of the focal construct, brand, is unclear. In other words, empirical results throughout the brand literature may apply to “brand” – by one definition or another – but there is no way of knowing which brand interpretation is in use.

Originality/value
A large part of the marketing field does not know what the word “brand” means anymore, a lapse that is widely unrecognized. This paper illuminates the lost knowledge condition and proposes resolution. The present state of theoretical and empirical ambiguity is untenable because so many empirical findings throughout the literature are vitiated.
Understanding household waste separation in South Africa
Authors: Issock Issock Paul Blaise , Roberts-Lombard Mornay , Mpinganjira Mercy 
Published: March 2020

PurposeThe aim of this paper is to examine the motives behind the separation of household waste (or the lack of such separation) on the basis of the theory of interpersonal behaviour. The aim of this paper is to broaden and deepen the understanding of key determinants of household waste separation (or the lack of such separation). This study proposes a conceptual model based on the theory of interpersonal behaviour in combination with the focus theory of normative conduct.Design/methodology/approachA quantitative method was applied to investigate the views of 350 heads of households in the Johannesburg metropolitan area through an administered questionnaire. Structural equation modelling was employed to test the hypothesised structural relationships in the proposed model.FindingsThe results indicate that household waste separation intention is influenced by cognition of the consequences and by injunctive and personal normative pressures. Separation intention and past habits were found to have a direct influence on actual separation behaviour.Originality/valueWhile the theory of planned behaviour is ubiquitous in the recycling literature, this study presents a different, broader framework for a better understanding of the drivers of household waste separation. This is achieved by applying the theory of interpersonal behaviour in combination with the focus theory of normative conduct. The findings provide insights that could help municipalities in emerging markets to promote household waste separation for better management of the environment.
A meta-analytic examination of the relationship between family firm generational involvement and performance
Authors: Kosmidou Vasiliki 
Published: March 2020

PurposeThe purpose of this paper is to examine the relationship between family firm generational involvement and performance. Although researchers have studied this relationship extensively, a complete understanding of its true magnitude and sign is still lacking.Design/methodology/approachThis meta-analysis sheds new light on this relationship, integrating the findings of 43 studies with 51 independent samples and 18,802 family firms.FindingsThe results reveal a small and negative relationship indicating that later-generation family firms perform worse compared to first-generation ones. The authors also show that the relationship is stronger for younger than older and for private than public firms. Finally, the measurements of both variables influence the relationship yielding critical research implications.Research limitations/implicationsThis study suggests that future researchers examining the effects of generational involvement on family firm performance should conduct their analysis using multiple measures of both variables to ensure the accuracy of their results. It also highlights the need of family business scholars to converge to the use of a universal family firm definition, as findings differ significantly in strength and direction depending on which definition is used.Practical implicationsFrom a practitioners’ perspective, the findings imply that owners of young and private family firms should consider professionalizing and adopting a balanced top management team composition consisting of both family and non-family members as a way to mitigate the negative effects of “familiness” on performance.Originality/valueThis study empirically demonstrates the importance of adopting a generational perspective when examining differences in family firm performance.
Supply chain MFCA implementation: emphasizing evidence on coordination
Authors: Higashida Akira 
Published: March 2020

PurposeThis study aims to clarify systematically the contribution of material flow cost accounting (MFCA) to green supply chain management (GSCM) by examining the coordination mechanisms.Design/methodology/approachTwo qualitative case studies are conducted in a major Japanese manufacturing company, which introduced MFCA in two different supply chains. The concept of coordination mechanisms in supply chain management is used to consolidate the understanding on the usefulness of MFCA in GSCM.FindingsThe study’s findings reveal the significant role played by MFCA in coordinating material flows and eliminating sub-optimization in the supply chain from both economic and environmental perspectives. Furthermore, the focal company in the chain has an important role as the MFCA leader in implementing MFCA in the chain. In particular, the environmental department can eliminate suppliers’ concerns regarding opportunistic buyer behaviors and focus on material flows across the supply chain.Research limitations/implicationsThe study highlights the possibility of reviewing existing transactions by coordinating material flows. This is a new direction for the adoption of MFCA in GSCM. In addition, although the study highlights the importance of the environmental department as an MFCA leader, future research is necessary to establish this aspect with greater precision.Practical implicationsThe two case studies discussed in this paper demonstrate the usefulness of MFCA expansion into the supply chain, as well as information sharing and progression, in the development of GSCM.Social implicationsThis study will contribute to enhance the green supply chain by implementing MFCA.Originality/valueThis study indicates that MFCA can potentially reveal the material losses caused by sub-optimization and provide information to avoid sub-optimization in decision-making. Moreover, it highlights the importance of the environmental department as an MFCA leader.
The changing postdoc and key predictors of satisfaction with professional training
Authors: Van Benthem Kathleen , Nadim Adi Mohamad , Corkery Christopher T. , Inoue Jiro , Jadavji Nafisa M. 
Published: March 2020

Purpose
The postdoctoral position was originally created as a short training period for PhD holders on the path to becoming university professors; however, the single-purpose paradigm of training has evolved considerably over time. The purpose of this paper is to report on the opportunities and challenges faced by postdocs as they navigate this complex training period.

Design/methodology/approach
To better understand the changes in postdoctoral training the Canadian Association of Postdoctoral Scholars – l’Association Canadienne des Stagiaires Postdoctoraux (CAPS-ACSP) conducted three professional national surveys of postdocs working in Canada and Canadian postdocs working internationally. Using the data from each survey, the authors investigated demographics, career goals and mental health and developed a theory-based path model for predicting postdoctoral training satisfaction, using structural equation modeling.

Findings
The analysis revealed that during their training postdocs face mental health symptoms, which play a role in job satisfaction. Additionally, predictors of satisfaction with career training were opportunities for skills development and encouragement from supervisors. Predictors of satisfaction with compensation were salary, skills training, mental health and encouragement from supervisors.

Originality/value
This first in-depth analysis of mental health symptoms illuminates the postdoc experience in academia. The study highlights the need for substantive changes to address the challenges facing postdoctoral training in the current research model in North America.
