Is craft beer consumption genderless? Exploratory evidence from Italy and Germany
Authors: Rivaroli Sergio , Lindenmeier Jörg , Spadoni Roberta 
Published: February 2020

PurposeThis study aimed to investigate the gendered nature of craft beer (CB) consumption in Italy and Germany.Design/methodology/approachData were collected through online surveys in Italy (N = 210) and Germany (N = 211). Based on an enhanced version of the theory of planned behaviour, mean value difference tests and moderated regression analyses with gender as a moderator were performed to test gender effects on CB consumption behaviour.FindingsThe study results provide evidence that the gap in CB consumption behaviour is not very pronounced. In the German sample, gender did not moderate the effects of the model components on behavioural intent. However, the study found significant mean differences in all model variables. In the Italian sample, gender moderated the effects of several components of the theory of planned behaviour on behavioural intention. Hence, CB consumption appears to represent an opportunity for Italian women to negotiate their womanhood in a historically masculine-dominated space.Research limitations/implicationsThe limitations of these data are the focus on two specific countries, the use of small-sized samples and the prediction of behavioural intentions instead of actual behaviour.Practical implicationsThe study may help marketing managers develop appropriate marketing strategies based on a better understanding of gender-specific needs in CB consumption.Originality/valueThis investigation provides the first comparative analysis of gender-specific behavioural patterns in CB consumption in two European countries characterised by notably different beer cultures.
Variable speed PMSG design and implementation for wind driven welding power source
Authors: S. Vinod , M. Balaji 
Published: February 2020

Purpose
The purpose of this paper is the attempt to model a variable speed permanent magnet synchronous generator (PMSG) for extracting a standalone power source to assuage the needs of a welding application. The emphasis orients to evolve a framework for the effective exploration of renewable energy resource and prevent the injection of grid harmonics.

Design/methodology/approach
The system involves the use of self-commutated dc-dc converter interfaces to extradite the current and voltage requirements of the welding attributes. The philosophy incites a pulse width formulation for reducing the voltage ripples in the dc output and improving the time response characteristics.

Findings
The proper selection of closed loop Fuzzy tuned PI control ensures the restriction on the magnitude of the current drawn from the source, enhances the dynamic response and betters steady state response.

Originality/value
PMSG-based welding power source with parallel-connected cascaded buck fed cuk converters. MATLAB-based simulation of the methodology offer interesting results in the sense it orchestrates the range of converter operation and the ability to provide a high-quality weld without polluting the ac mains. The experimental prototype further proliferates to validate the simulated performance and claims a space for its use in the real-world utilities.
Understanding user acceptance of blockchain-based smart locker
Authors: Lian Jiunn-Woei , Chen Chih-Teng , Shen Li-Fang , Chen Hung-Ming 
Published: February 2020

PurposeThe purpose of this study is to explore the critical factors that affect users’ acceptance and usage intention toward blockchain-based smart lockers.Design/methodology/approachThe research is designed in two phases. In the first phase, the key stakeholders are interviewed. Participants include managers from technology providers and logistics companies. In the second phase, a questionnaire survey is used to validate the proposed model.FindingsBased on the final results, this study makes the following three suggestions. First, perceived usefulness and perceived ease of use are the critical factors. In other words, it is important to emphasize the function and convenience of a new service when introducing it to a potential user. Second, safety is not the major concern when using a blockchain-based smart locker. This means that users will trust the service provider for providing a secure service. Users do not worry about the security problem. Finally, the network externality of smart locker is also insignificant.Originality/valueThis study has three major contributions. First, this study identifies the critical factors that will affect user acceptance of blockchain-based smart lockers. Next, this study combines the opinions from service providers and users to understand the gap between different stakeholders. Finally, this study can enrich our understanding on the applications of blockchain from a managerial perspective and not only from a technical perspective, as in most previous studies.
A trustworthy network or a technologically disguised scam
Authors: Issac Abraham Cyril , Baral Rupashree 
Published: February 2020

Purpose
The initiation of cryptocurrency such as bitcoin has invoked a general curiosity in the international financial regime. Bitcoin works in a peer-to-peer framework with no third party acting as a monitoring agency. This brings in both positive and negative spirit to the table. Though generic understanding is available, the studies done on bitcoin and blockchain are far and few. The purpose of this paper is to decipher the level of understanding the scientific world has on bitcoin and the underlying blockchain and thereby to find out the pertinent research gaps existing in this field.

Design/methodology/approach
A biblio-morphological analysis is undertaken which underscores a comprehensive framework characterizing the bitcoin and blockchain literature in terms of dimensions and options. This was developed as a result of extensive scanning of the relevant literature.

Findings
The biblio-morphological analysis broadly outlines the present status of the research on the topic. The morphological analysis brings out the 169 research gaps that exist in the area of bitcoin and underlying blockchain technology. The cross-consistency matrix underscores the fact that this novel technology bears large research potential.

Research limitations/implications
The biggest contribution of this paper would be to underline the present status of the literature on bitcoin and blockchain technology. This study attempts to make this document a vade mecum for both the industry and the academia in the area of bitcoin and blockchain technology. The blockchain technology and its effects and influences on other disciplines can effectively be explored by taking cues from the gaps identified by this biblio-morphological analysis. Such unique combinations can open up new avenues of research in the broader realm of business and economics.

Originality/value
To the best of the authors’ knowledge, this is a first comprehensive biblio-morphological analysis on bitcoin and underlying blockchain technology, which characterizes blockchain literature and thereby offers to reduce redundant research by delineating the possible avenues in the area of blockchain technology.
Predatory publishing through McCornarck’s information manipulation theory
Authors: Bett Harry Kipkemoi 
Published: February 2020

Purpose
The purpose of this paper is to analyse how predatory journals use spam emails to manipulate potential authors. This has been done based on McCornack’s information manipulation theory (IMT). Generally, predatory publishing is on the increase globally but more pronounced in developing countries. Although it affects both young and seasoned scholars, inexperienced scholars and those ignorant on credible publishing are the most affected.

Design/methodology/approach
The current study through document analysis focuses on email invites from predatory journals sent to the author between June 2016 and December 2018 after publishing a peer-reviewed journal article. The resultant texts were analysed using a directed qualitative content analysis.

Findings
Findings indicate that the invites flouted all the four Gricean maxims (of quality, quantity, manner and relevance) as posited by IMT. This suggests that the spam mails sent to the author sought to manipulate potential authors to publish with predatory journals.

Research limitations/implications
This qualitative study focuses on email invites to the author which may not fully capture the manipulation by predatory journals.

Practical implications
It is important that scholars in developing contexts are aware of how predatory publishers seek to manipulate their victims. Universities and research institutions should be intentional in enlightening their academic staff on predatory journals and their characteristics. Similarly, universities should consider disincentivising their faculty members who publish in such platforms.

Originality/value
The originality in this study lies in its use of IMT to explain how predatory journals manipulate potentials authors.
Conventional procedurevis-à-visbootstrap-based corrections of efficiency analyses
Authors: Valiyattoor Vipin , Bhandari Anup Kumar 
Published: February 2020

PurposeThis paper aims to evaluate the performance of basic metals industry in India and analyze its determinants, using data envelopment analysis (DEA) method. It also intends to compare the results through conventional two-stage and bootstrap-based inferences.Design/methodology/approachConsidering technical efficiency as a measure of performance, this paper specifically investigates whether the participation of a firm in the global market affects its performance. The conventional two-stage procedure is used to test the export intensity and firm performance nexus. The bootstrap-based algorithms (by Simar and Wilson, 2007) are used to correct the bias and serial correlation issues involved in the conventional approach.FindingsThe result shows a negative relation between export intensity and firm performance while following the conventional procedure. Even after accounting for serial correlation, the relation remains more or less similar to that of conventional analysis. However, a strong negative relation between export intensity and firm performance is not observed in a more reliable inference obtained after correcting for possible bias as well as serial correlation.Research limitations/implicationsThis paper is based on cross-sectional analysis, and a more reliable result can be obtained by considering a larger sample and longer period.Originality/valueThis paper shows how the conventional two-stage procedure may result in misleading inferences due to bias in the estimation of efficiency scores and the serial correlation during the second stage inferential analysis. This paper also empirically exemplifies how the double bootstrap DEA procedure can overcome these limitations of the conventional two-stage approach.
Evolutionary information dynamics over social networks: a review
Authors: Zhang Hangjing , Chen Yan , Zhao H. Vicky 
Published: February 2020

Purpose
The purpose of this paper is to have a review on the analysis of information diffusion based on evolutionary game theory. People now get used to interact over social networks, and one of the most important functions of social networks is information sharing. Understanding the mechanisms of the information diffusion over social networks is critical to various applications including online advertisement and rumor control.

Design/methodology/approach
It has been shown that the graphical evolutionary game theory (EGT) is a very efficient method to study this problem.

Findings
By applying EGT to information diffusion, the authors could predict every small change in the process, get the detailed dynamics and finally foretell the stable states.

Originality/value
In this paper, the authors provide a general review on the evolutionary game-theoretic framework for information diffusion over social network by summarizing the results and conclusions of works using graphical EGT.
Collaborative filtering recommendation algorithm based on variational inference
Authors: Zheng Kai , Yang Xianjun , Wang Yilei , Wu Yingjie , Zheng Xianghan 
Published: February 2020

Purpose
The purpose of this paper is to alleviate the problem of poor robustness and over-fitting caused by large-scale data in collaborative filtering recommendation algorithms.

Design/methodology/approach
Interpreting user behavior from the probabilistic perspective of hidden variables is helpful to improve robustness and over-fitting problems. Constructing a recommendation network by variational inference can effectively solve the complex distribution calculation in the probabilistic recommendation model. Based on the aforementioned analysis, this paper uses variational auto-encoder to construct a generating network, which can restore user-rating data to solve the problem of poor robustness and over-fitting caused by large-scale data. Meanwhile, for the existing KL-vanishing problem in the variational inference deep learning model, this paper optimizes the model by the KL annealing and Free Bits methods.

Findings
The effect of the basic model is considerably improved after using the KL annealing or Free Bits method to solve KL vanishing. The proposed models evidently perform worse than competitors on small data sets, such as MovieLens 1 M. By contrast, they have better effects on large data sets such as MovieLens 10 M and MovieLens 20 M.

Originality/value
This paper presents the usage of the variational inference model for collaborative filtering recommendation and introduces the KL annealing and Free Bits methods to improve the basic model effect. Because the variational inference training denotes the probability distribution of the hidden vector, the problem of poor robustness and overfitting is alleviated. When the amount of data is relatively large in the actual application scenario, the probability distribution of the fitted actual data can better represent the user and the item. Therefore, using variational inference for collaborative filtering recommendation is of practical value.
College students’ understanding of social justice as sustainability
Authors: Kruger Tina M. , McCreary Nicholas , Verhoff Brandon L. , Sheets Virgil , Speer James H. , Aldrich Stephen P. 
Published: February 2020

Purpose
The purpose of this study was to explore college students’ understanding of sustainability and, specifically, the extent to which students see social justice as being integral to sustainability.

Design/methodology/approach
Between fall 2015 and 2017, an online survey study was deployed to students at a Midwestern University in the USA to assess attitudes and concerns about environmental issues and awareness of the university’s activities related to these issues. This analysis included ten assessment items from a larger study, of which 1,929 participants were included in the final sample. A chi-square goodness-of-fit and variable cluster analysis were performed on the included items.

Findings
Items such as “recycling,” “economic viability” and “fair treatment of all” were identified as integral to the concept of sustainability, while items such as “growing organic vegetables” and “reducing meat consumption” had high levels of “not applicable” and “don’t know” responses, with differences arising across gender and class standing. Social justice-related items were seen as more distally connected to sustainability.

Research limitations/implications
This study is limited by a non-random sample of students.

Practical implications
College students tend not to recognize the integral nature of social justice or the relevance of food to sustainability, providing an opportunity for universities to better prepare their students for a sustainable future.

Social implications
Universities might adopt policies and curricula that address these areas of ignorance.

Originality/value
This study is among the first to identify specific areas of college students’ lack of understanding about sustainability.
How can national governance affect education quality in Western Europe?
Authors: Gerged Ali , Elheddad Mohamed 
Published: February 2020

Purpose
As the international society faces unprecedented challenges associated with resource scarcity, governance scandals, increasing injustice and inequality, new opportunities for higher education institutions are emerging. This paper aims to investigate the association between national governance standards and education quality across nine western European countries, namely, the UK, Germany, France, Finland, Norway, Switzerland, Sweden, Denmark and Ireland.

Design/methodology/approach
Using panel data from 2002 to 2017, this paper uses fixed-effects and random-effects models to examine the relationship between national governance (proxied by voice and accountability (V&A) indicator) and education quality (proxied by human development index: education index). This analysis is supplemented with conducting instrumental variable (IV) estimations to address any concerns regarding the expected occurrence of endogeneity problems.

Findings
The findings are suggestive of a significant and positive relationship between national governance and education quality in Europe. This implies that national governance standards, such as V&A, are essential actors in the enhancement of the quality of educational institutions’ outcomes.

Research limitations/implications
Policymakers should implement stricter regulations and ensure that accountability indicators are motivated if they wish to increase the spending on education, which is associated with better qualities of educational institutions. A culture of continuous review of education policies needs to be upheld in the Western Europe region to be watchful of any emerging problems while maintaining a sustainable relationship between the rule of law and the education administration.

Originality/value
So far, a minimal number of studies focussed on examining the role of country-level governance in advancing education quality. This study, therefore, extends the body of prior literature by investigating the possible effect of national governance structures on education quality across a sample of Western European countries.
One visitor too many: assessing the degree of overtourism in established European urban destinations
Authors: Amore Alberto , Falk Martin , Adie Bailey Ashton 
Published: February 2020

Purpose
The purpose of this study is to provide a series of indicators to determine the limits to urban tourism growth, tourism gentrification and overtourism. The study addresses overtourism within the frame of urban liveability through a proxy analysis of tourism-relevant indicators for major European tourist cities.

Design/methodology/approach
Based on the various indicators, a composite overtourism indicator is derived. The following dimensions are considered for the composite indicator: total number of overnight stays per relevant tourist area in km2; number of museum visitors per population; average annual change in total nights between 2009 and 2017; and foreign nights per population.

Findings
Based on the results, Venice is the city with the highest degree of overtourism, followed by Florence, Seville and Lisbon. The remaining cities have a lower than average overtourism potential as indicated by the negative z-score.

Research limitations/implications
This study and the composite overtourism indicators are only a starting point that can lead to further research in the field. Recommendations for further studies include the assessment of visitor flow and overtourism at different times of the year and to expand the study to other European urban destinations.

Practical implications
The paper suggests that policymakers should use these indicators when managing urban tourism development and monitoring visitor growth. Furthermore, they can be a starting point from which to assess the impact of tourism on the quality of life of local residents.

Social implications
This study provides a starting point from which to assess the causes for social unrest tied to overtourism. If the city under study is found to have a lower than average overtourism potential, this indicates that there may be other social or psychological issues at play apart from sheer overcrowding.

Originality/value
To date, there has been no composite indicator that considered the different numerical aspects of overtourism altogether. This study provides a set of key indicators and a composite overtourism indicator to provide a preliminary appraisal of overtourism as a demand-side phenomenon with evidence from a range of established European urban destinations.
Design and locomotivity analysis of a novel deformable two-wheel-like mobile mechanism
Authors: Zhang Qianqian , Li Yezhuo , Yao Yan-An , Li Ruiming 
Published: February 2020

Purpose
The purpose of this paper is to propose a deformable two-wheel-like mobile mechanism based on overconstrained mechanism, with the abilities of fast rolling and obstacle surmounting. The drive torque of the multi-mode motions is generated by self-deformation. Moreover, the analyses of feasibility and locomotivity of two mobile modes are presented.

Design/methodology/approach
The main body of the two-wheel-like mobile mechanism is a kind of centrally driven 4 R linkages. The mobile mechanism can achieve the capabilities of fast rolling and obstacle surmounting through integrating two mobile modes (spherical-like rolling mode and polyhedral-like obstacle-surmounting mode) and can switch to the corresponding mode to move or surmount obstacles. The mobility and kinematics of the mobile modes are analyzed.

Findings
Based on the results of kinematics analysis and dynamics analysis of the wheel-like mechanism, the spherical-like rolling mode has the capability of fast rolling, and the polyhedral-like obstacle-surmounting mode has the capability of surmounting different obstacle heights by two submodes (quasi-static obstacle-surmounting submode and dynamic obstacle-surmounting submode). The proposed concept is verified by experiments on a physical prototype.

Originality/value
The work presented in this paper is a novel exploration to apply bar linkages in the field of scout. The two-wheel-like mobile mechanism improves the torque imbalance of bar linkages by centrally driven method, removes the rear support structures of the traditional two-wheeled mechanisms by self-deformation and increases the height of obstacle surmounting by mode switching angle.
