Crystal and geometry-optimized structure of an anthracene-based Diels–Alder adduct
Authors: Hillman Zachary E. , Tanski Joseph M. , Roberts Andrea 
Published: June 2020

Computational calculations of an anthracene-based Diels–Alder adduct, namely, 17-ethyl-1-hydroxymethyl-17-azapentacyclo[6.6.5.02,7.09,14.015,19]nonadeca-2,4,6,9,11,13-hexaene-16,18-dione, C21H19NO3, predicting density functional theory (DFT) optimized geometries in the gas phase are compared in terms of accuracy relative to the solid-state crystal structure and computational cost. Crystal structure determination and Hirshfeld surface analysis of the racemic product reveal that the molecules are linked by O—H...O=C hydrogen bonds between the hydroxy and carbonyl groups, accounting for 9.5% of the intermolecular contacts, while H...H contacts represent 56.9% of the total. Boltzmann population analysis of computed relative rotamer abundances in the gas phase are based on lower-level geometry optimization and thermochemical corrections coupled with higher-level electronic energy calculations using the B2PLYP double-hybrid functional. As expected, the choice of density functional has a greater effect than the basis set on accuracy for all levels of theory. For any given functional, increasing the basis set size did not always correlate with increasingly accurate structures. The hybrid functional B3LYP without dispersion correction routinely gave the closest approximations to the crystal structure where the B3LYP/aug-cc-pVDZ combination afforded the best structure (r.m.s. deviation = 0.1314 Å). However, the B3LYP/6-31+G(d,p) level of theory represents the best compromise between accuracy (r.m.s. deviation = 0.1388 Å) and cost as it yielded appreciably accurate results in a fraction of the time compared to other method combinations.

Published: June 2020

PurposeThis study aimed to look at parents' perceptions of a number of different toy prototypes that represented physical impairments and predictors of these perceptions.Design/methodology/approachA correlational survey design was used. Parents of children aged 4–10 years who identified their child as having a disability (n = 160) and not as having a disability (n = 166) took part. They rated a number of prototypes for likelihood that their child would enjoy playing with them and completed measures of their responses toward children with disabilities and of their own and their child's direct contact with people with disabilities.FindingsIt was found that, among parents of children who did not declare that their child had a disability, the more open the parents were toward disability, the more contact the children had with other children with disabilities and the more likely they were to consider that their child would like to play with a toy prototype representing a physical impairment. This pattern of results was not found among parents who identified their child as having a disability, where instead positive friendship intentions of parents mediated this association.Research limitations/implicationsThese findings have implications for theories informing the positive benefits of disability representation.Practical implicationsThese findings indicate different paths through which parents might be moved to purchase toys that represent physical impairments for their children.Social implicationsThese findings suggest that representative toys might be associated with an open dialogue around the topic of disability.Originality/valueThis is the first study of the responses of parents to toys that represent physical impairments known to the authors.
Implementing standardised flow: navigating operational and professional dependencies
Authors: Frangeskou Marianna , Lewis Michael A. , Vasilakis Christos 
Published: June 2020

PurposeThe purpose of this study had two aims: (1) to extend insight regarding the challenges of implementing standardised work, via care pathways, in a healthcare setting by considering interactions with other operational (i.e. resource sharing, portfolio alignment) and professional (i.e. autonomous expertise) dependencies and (2) to develop novel insights regarding a specific flow mechanism, the stroke nurse practitioner, a form of flow “pilo” or guide.Design/methodology/approachThis was a longitudinal case study of implementing the acute stroke care pathway in a National Health Service hospital in England based on 185 hours of non-participant observations and 68 semi-structured interviews. Archival documents were also analysed.FindingsThe combined flow, operational and professional dependency lens extends operations management understanding of the challenge of implementing standardised work in healthcare. One observed practice, the process pilot role, may be particularly valuable in dealing with these dependencies but it requires specific design and continuous support, for which the authors provide some initial guidance.Research limitations/implicationsThe research was a single case study and was focussed on a single care pathway. The findings require replication and extension but offer a novel set of insights into the implications of standardised work in healthcare.Originality/valueIn addition to confirming that a multidependency lens adds conceptual and practical insight to the challenges of implementing standardised work in a healthcare setting, the findings and recommendations regarding flow “pilots” are novel. The authors' analysis of this role reveals new insights regarding the need for continued improvisation in standardised work.

Authors: Namagembe Sheila 
Published: June 2020

PurposeThe study examined the influence of environmental standards set by the SME agro-based processing firms and farmers' environmental empowerment on farmers' adoption of environmentally friendly agricultural practices; and the mediating role of empowerment on the relationship between SME agro-based processing firm environmental standards and farmers' adoption of environmentally friendly agricultural practices.Design/methodology/approachData was collected from purchasing managers of the agro-based processing firms. The SPSS software, SMART PLS and CB-SEM software were used to obtain results on the influence of environmental standards set by the SME agro-based processing firms on adoption of environmentally friendly agricultural practices; the influence of farmers' environmental empowerment on adoption of environmentally friendly agricultural practices and the mediating role of farmers' environmental empowerment on the relationship between SME agro-based processing firm environmental standards and farmers' adoption of environmentally friendly agricultural practices.FindingsFindings indicated that SME agro-processing environmental standards have an influence on farmers' adoption of environmentally friendly agricultural practices. Empowering farmers in environmental issues influenced their adoption of environmentally friendly agricultural practices. A partial mediation effect was observed on testing the mediating role of farmers' environmental empowerment on the relationship between SME agro-based processing firm environmental standards and farmers' adoption of environmentally friendly practices.Research limitations/implicationsThe study mainly focused on the upstream part of agricultural supply chains. The research has implications to decision-makers in government concerned with enhancing environmentally friendly practices among farmers in general.Originality/valueThe influence of SME agro-based processing firm environmental standards on farmers' adoption of environmentally friendly agricultural practices; the influence of farmers' environmental empowerment on farmers' adoption of environmentally friendly practices; and the mediating role of farmers' environmental empowerment on the relationship between SME agro-based processing firm environmental standards and farmers' adoption of environmentally friendly agricultural practices are aspects that have not been given significant attention.
Statistical software fault management based on bootstrap confidence intervals
Authors: Dohi Tadashi , Okamura Hiroyuki , Qian Cun Hua 
Published: June 2020

PurposeIn this paper, the authors propose two construction methods to estimate confidence intervals of the time-based optimal software rejuvenation policy and its associated maximum system availability via a parametric bootstrap method. Through simulation experiments the authors investigate their asymptotic behaviors and statistical properties.Design/methodology/approachThe present paper is the first challenge to derive the confidence intervals of the optimal software rejuvenation schedule, which maximizes the system availability in the sense of long run. In other words, the authors concern the statistical software fault management by employing an idea of process control in quality engineering and a parametric bootstrap.FindingsAs a remarkably different point from the existing work, the authors carefully take account of a special case where the two-sided confidence interval of the optimal software rejuvenation time does not exist due to that fact that the estimator distribution of the optimal software rejuvenation time is defective. Here the authors propose two useful construction methods of the two-sided confidence interval: conditional confidence interval and heuristic confidence interval.Research limitations/implicationsAlthough the authors applied a simulation-based bootstrap confidence method in this paper, another re-sampling-based approach can be also applied to the same problem. In addition, the authors just focused on a parametric bootstrap, but a non-parametric bootstrap method can be also applied to the confidence interval estimation of the optimal software rejuvenation time interval, when the complete knowledge on the distribution form is not available.Practical implicationsThe statistical software fault management techniques proposed in this paper are useful to control the system availability of operational software systems, by means of the control chart.Social implicationsThrough the online monitoring in operational software systems, it would be possible to estimate the optimal software rejuvenation time and its associated system availability, without applying any approximation. By implementing this function on application programming interface (API), it is possible to realize the low-cost fault-tolerance for software systems with aging.Originality/valueIn the past literature, almost all authors employed parametric and non-parametric inference techniques to estimate the optimal software rejuvenation time but just focused on the point estimation. This may often lead to the miss-judgment based on over-estimation or under-estimation under uncertainty. The authors overcome the problem by introducing the two-sided confidence interval approach.
Consumers’ decision to boycott “unethical” products: the role of materialism/post materialism
Authors: Delistavrou Antonia , Krystallis Athanasios , Tilikidou Irene 
Published: June 2020

PurposeAlthough boycotting campaigns have been increasing, a limited amount of academic research has been focussed on the antecedents of consumers’ participation in the retail field. This paper presents an examination of consumers’ intentions to boycott the “unethical” supermarket products by a Theory of Planned Behaviour (TPB) application. Materialism/Post-materialism was incorporated in the research as a moderating variable.Design/methodology/approachPersonal interviews were taken in a sample (420) selected by a probability sampling method. Structural equation modelling was performed to analyse the data.FindingsTPB was found powerful to explain boycotting intentions. Consumers, who more strongly intent to boycott, are affected more by social norms than by attitudes and perceived behavioural control. Those consumers believe more strongly that boycotting “unethical” retail products will generate valuable outcomes, will comply with their referents’ expectations and will not be obstructed by any barriers. Post-materialists were found to hold stronger intentions than materialists. Materialists are mostly influenced by their attitudes and their perceived control over participation in boycotting. On the contrary, post-materialists are solely influenced by their feelings regarding social pressure to boycott.Research limitations/implicationsControl for social desirability should be included in future research. National or multinational samples more effective for generalization. The ability of other psychographics or demographics to moderate TPB relationships could be further investigated.Practical implicationsRetailers, who try to avoid potential boycotts, should primarily aim to diminish the social influence towards boycotting. Secondarily, they should aim to decrease the consumers’ positive attitudes and perceived controllability over participation in boycotting. On the other side, consumers’ groups or associations when designing a boycott campaign should address their call targeting to post-materialist consumers. Messages for a boycotting call should enhance the important referents’ pressure towards a friendlier society in which people’s action is able to ethics in the market.Originality/valueIn this study, TPB was expanded by the incorporation of values, namely Materialism/Post-materialism, as a moderating factor.

Authors: Sun Yuan , Zhu Mengjie , Jeyaraj Anand 
Published: June 2020

PurposeEnterprise social media (ESM) are widely adopted in the organizations with the aim of improving employees' work performance. The purpose of this paper is to investigate the moderating effects of work context characteristics on the relationships between proactive motivations and usage behaviors of ESM communication and task collaboration feature sets.Design/methodology/approachQuestionnaire surveys were used to gather data from 307 randomly chosen Chinese employees, who were also ESM users. The research model was examined using linear regression methods with the SPSS 24 software package.FindingsThe results indicate that work context characteristics (i.e. task interdependence and perceived organizational support) had significant moderating effects on the relationships between proactive motivations and usage behaviors.Originality/valueBy extending the model of proactive motivation to the ESM context, this study directly addresses how users can be energized to use ESM features.

Authors: Dambiski Gomes de Carvalho Gustavo , Alisson Westarb Cruz June , Gomes de Carvalho Hélio , Carlos Duclós Luiz , Oliveira Corrêa Rúbia 
Published: June 2020

PurposeThis research aims to analyze the relations between coopetition and innovation, by comparing two coopetitive tourism SMEs networks in Brazil.Design/methodology/approachThe first network comprises 23 SMEs in Honey Island, a natural reserve, and the second network comprises 21 out of 25 SMEs in the Campos Gerais region, recognized by its strong agribusiness. Innovativeness variables included innovation inputs, capabilities, and outputs; and four types of relations that foster innovation were considered, namely, commercial, informational, knowledge, and partnerships. Social network analysis was employed as well as statistical analyses such as Kolmogorov–Smirnov, Mann–Whitney, Spearman correlation and Fischer'sZtransformation.FindingsResults show that coopetition is related to SMEs innovativeness. Commercial relations centralities correlated with many innovation outputs, information and knowledge centralities with some innovation inputs and outputs, and partnerships also with capabilities.Research limitations/implicationsBesides contributing to the literature of innovation in tourism, this paper also contributes to the literature on coopetition and innovation by investigating how different types of coopetition relationships foster innovation inputs, capabilities, and outputs.Practical implicationsManagers may benefit from these findings by fostering specific innovation inputs, capabilities, or outputs by means of different coopetition relations. Similarly, regional tourism policy planners may also improve the innovativeness of tourism small businesses by fostering coopetition networks.Originality/valueThis paper not only compares the innovativeness of two small business coopetition networks in the tourism industry but also analyses quantitively in detail how different types of coopetition relations are related to different innovativeness variables.

Practical implications
The research is useful for government authorities, law authorities and offices and the democratic society as a whole.

Originality/value
To the best of the author’s knowledge, this is the first study examining the specific topic.
Leaders can facilitate creativity: the moderating roles of leader dialectical thinking and LMX on employee creative self-efficacy and creativity
Authors: Han Guohong Helen , Bai Yuntao 
Published: June 2020

PurposeResearch has shown that creative self-efficacy is an important antecedent of workplace creativity, but recent research indicates that this relationship may be moderated by contextual factors. The current study investigates whether leader dialectical thinking and leader member exchange moderate the relationship between employee creative self-efficacy and employee creativity.Design/methodology/approachA survey sample of 222 employees in 43 teams from Chinese high-tech companies was collected and HLM was used to test our research model.FindingsThe positive association between employee creative self-efficacy and employee creativity was strengthened when a leader displayed a dialectical thinking style. Additional analyses failed to find support for the moderating role of leader-member exchange (LMX).Research limitations/implicationsThese findings establish leadership cognitive style as a potential boundary condition of the relationship between creative self-efficacy and employee creativity.Practical implicationsCompanies can make an active effort in recruiting and training leaders who have a dialectical mindset as they can play significant roles in facilitating employee creativity.Social implicationsTechnological advancement and innovation is important for social welfare. This paper helps to improve the efficiency of creativity processes and finally benefits the whole society.Originality/valueThis is the first introduction of the leader's dialectical thinking as a moderator of the relationship between creative self-efficacy and creativity.
Religions going nuts? Faith-based veganism and transformative learning in the context of sustainability transitions (case 1: The Hare Krishna movement)
Authors: Lestar Tamas 
Published: June 2020

PurposeThis paper is based on several years of ethnographic and desk-based research studying the Hare Krishna movement. The work is the first in a series exploring how segments of specific faith communities embrace dietary veganism and how this relates to the concept of transformational learning/change in the context of sustainability transitions. The focus is on how these communities embrace a plant-based diet representing different rationales and attitudes of learning in the process of organisational change.Design/methodology/approachI investigated Krishna practices extensively by visiting and volunteering in several of its farm communities in Europe. I used the mixed method of qualitative observations, participation, in-depth interviews and email interviews during a period of ten weeks spent in the communities altogether. I had not been in contact with Hare Krishna believers before the fieldwork.FindingsKrishna veganism is analysed in the context of sustainability transitions by drawing on the concept of transformative (third-order) learning/change. Findings reveal an unexpected tendency to veganism despite the movement's worldview and radical commitment to dairy consumption. By calling into question their own collective dietary paradigm, the Hare Krishna community provides an exemplary case of third-order learning and change in an organisational context.Originality/valueThe paper invites scholars to include third-order learning into sustainability transitions frameworks while aiming to address the shortcomings of theorising levels of learning. The connection between Krishna veganism, third-order learning and sustainability transitions has not been put forward before.

Authors: Sato Sho , Eto Yukari , Iwaki Kotomi , Oyanagi Tadashi , Yasuma Yu 
Published: June 2020

PurposeThis study aimed to understand better the user gaze behavior on bookshelves using eye-tracking technology.Design/methodology/approachAn eye-tracking experiment in a public library with 11 participants was performed. The impact of vertical shelf location of books on the number of times the books are looked at, the impact of horizontal location and the relationship between user behavior and location impact were examined by the findings.FindingsThe results showed that the vertical location of books has a significant impact on the number of times the books are looked at. More than 80% of the time spent looking at bookshelves was spent on books on the top to fourth rows. It was also revealed that the horizontal location of books has a little impact. Books located on the left side of shelves will be looked at significantly more often than those on the right side. No significant relationships between type of user behaviors and location impact were observed.Originality/valueThe study explored the impact of the vertical location of books on time spent looking at bookshelves using eye-tracking methodology. Few published studies do such experiments to address user gaze behavior on bookshelves. The study explored that the vertical location of books has a great impact, and horizontal location has a little impact on user gaze behavior.
