Abstract
Purpose
Hyperautomation is a technological concept whose popularity has been growing continuously since the German manufacturing industry “initiated” the Fourth Industrial Revolution (Industry 4.0), whereas, on the basis of theory, hyperautomation is a term still new and little recognized. This applies equally to scientific studies (articles, conference reports) and empirical studies (quantitative, qualitative). Therefore, this article attempts to fill definition gap that exists in the literature on management and quality sciences on the term hyperautomation.
Design/methodology/approach
The authors use literature review approach to identify the gaps in the existing literature on hyperautomation. They present a nominal definition of hyperautomation, discuss related issues and provide a comparative perspective between hyperautomation and automation.
Findings
The article’s findings include a precise definition of hyperautomation and the problems it raises. The authors point out that the term “hyperautomation” is still relatively new and underutilized in the management and quality sciences literature. It also compares hyperautomation to automation from several angles and emphasizes how it affects businesses, industries and other economic sectors.
Practical implications
Authors emphasize that in order to deploy hyperautomation successfully, enterprises must take a distributed and integrated approach.
Originality/value
This article addresses a gap in the management and quality sciences literature about the definition of hyperautomation. Authors give a thorough explanation of hyperautomation, along with relevant problems, useful implications and a comparison between hyperautomation versus automation.

Abstract
Purpose
Recommendation systems are a fundamental tool for hotels to adopt a differentiating competitive strategy. The main purpose of this work is to use machine learning techniques to treat imbalanced data sets, not applied until now in the tourism field. These techniques have allowed the authors to analyse the influence of imbalance data on hotel recommendation models and how this phenomenon affects client dissatisfaction.
Design/methodology/approach
An opinion survey was conducted among hotel customers of different categories in 120 different countries. A total of 135.102 surveys were collected over eleven quarters. A longitudinal design was conducted during this period. A binary logistic model was applied using the function generalized lineal model (GLM).
Findings
Through the analysis of a representative amount of data, the authors empirically demonstrate that the imbalance phenomenon is systematically present in hotel recommendation surveys. In addition, the authors show that the imbalance exists independently of the period in which the survey is done, which means that it is intrinsic to recommendation surveys on this topic. The authors demonstrate the improvement of recommendation systems highlighting the presence of imbalance data and consequences for marketing strategies.
Originality/value
The main contribution of the current work is to apply to the tourism sector the framework for imbalanced data, typically used in the machine learning, improving predictive models.

Abstract
Purpose
Fresh vegetables contain advantageous phytochemical components, making them one of the most significant sources of nutrition. The threat of harmful bacteria still exists because these vegetables are not heated in restaurants before being consumed. Therefore, this study aimed to evaluate the microbial quality of fresh vegetables in restaurants of different levels.
Design/methodology/approach
A total of 499 fresh vegetable samples (from sandwiches and fresh-cut vegetable salads) were collected from 3 different types of food service establishment: 201 from international restaurants (IRs), 210 from national restaurants (NRs), and 88 from cafeterias (CAs). The samples were prepared and inoculated on specific growth media. The aerobic mesophilic bacteria (AMB) Campylobacter spp., Staphylococcus aureus (S. aureus), Enterobacteriaceae, Escherichia coli (E. coli) and yeast and molds were counted, and Listeria monocytogenes, Salmonella spp. and Escherichia coli O157 were detected using specialized medium.
Findings
High counts of S. aureus, above 3 log cfu/g, suggested that 71.5% of samples collected from NRs and 77.3% from CA were not accepted, whereas 81.6% of samples collected from IRs were accepted. The low population of E. coli, less than 2 log cfu/g, suggested that 99.0, 97 and 92.0 % of samples collected from IRs, NRs and CA, respectively, were accepted. Listeria monocytogenes and Escherichia coli O157 were absent from every sample. One sample was positive for Salmonella spp. in each of the NR and CA sample groups.
Originality/value
RIs adhere to health and hygiene standards better than NRs and CAs, according to the findings of vegetable contamination tests.

Abstract
Purpose
This paper aims to evaluate the effect of consumption of a high-fat diet (HFD) rich with total saturated fats on adiposity and serum levels of vascular cell adhesion molecule (sVCAM-1), a biomarker of endothelial inflammation/dysfunction. Another aim is to evaluate whether supplementation of a phytosomal formulation of curcumin would reduce adiposity measures and sVCAM-1 levels in HFD rats.
Design/methodology/approach
The study was conducted on 17 male rats which were allocated to one of three feeding regimen groups: normal diet (ND); HFD, or HFD with dietary phytosomal curcumin (HFD-C). Anthropometric measures were recorded weekly up to 20 weeks of feeding intervention, at the end of which, sVCAM-1 levels were also compared with one-way ANOVA and Tukey post-hoc analysis.
Findings
The HFD group had the greatest values for raw anthropometric data, and there was a group difference in anthropometric measures, however there was no significant difference between HFD and HFD-C for any measure. The gain at 20 weeks from initial values did reveal significant differences in weight and abdominal circumference between HFD and HFD-C groups. There were significant group differences in sVCAM-1 levels, with only HFD-C displaying significant lower levels than HFD group.
Originality/value
This is the first study that shows the capacity of a phytosomal formulation of curcumin in reducing adiposity and sVCAM-1 levels during daily intake of saturated fats above the recommended level. The results are promising in that this formulation can protect against endothelial inflammation/dysfunction, and can be used as complimentary therapy to suppress dyslipidemia/obesity-related cardiovascular complications.

Abstract
Purpose
The purpose of this paper is to contribute to the discussion on how multinational company (MNC) headquarters (HQs) can manage the existing coopetition paradox to ensure innovation within the MNC. In contrast to the rather scarce previous research, the authors argue that HQ needs to solve the coopetition paradox under the sway of a parenting paradox. Hence, HQ faces a dual paradox.
Design/methodology/approach
Drawing on the literature on HQ’s role during MNCs’ innovation processes, this conceptual paper revisits the previously suggested HQ measures to enable coopetition among subsidiaries. By applying a sheer ignorance perspective, the authors contribute with a more nuanced understanding of the HQ’s role in innovation activities.
Findings
The article identifies four challenges as the HQ faces a parenting paradox that hinders its ability to solve the coopetition paradox: context specificity of subsidiaries’ innovation work, normative expectations of subsidiary managers, potential opportunistic behavior of HQ manager and HQ underestimation of needed resources. The article suggests that HQ needs to become more informed and preferably even embedded in the local innovation networks of its most important subsidiaries and that coopetition should not be managed solely on an HQ level.
Originality/value
Advocating a sheer ignorance perspective, the article pioneers in discussing the role that HQ plays in managing coopetition among subsidiaries in innovation activities.

Abstract
This book chapter takes an institutional perspective on competing logics in global markets concerned with sustainability values and how market actors in the form of buyers and sellers attempt to solve these conflicting situations. We do this by identifying competing institutional logics in global market contexts aiming for sustainability values, together with techniques for navigating these competing institutional logics in the organizational field studied. As an empirical illustration, we use a case study of buyers and sellers in two different markets where sustainability has come into focus for their market relationships. This viewpoint allows us to better understand how global market actors deal with the competing institutional logics in their market context. We make three contributions with this research: firstly, we identify the institutional logics in global markets towards sustainability; secondly, we demonstrate how global market actors prioritize among the competing logics and their market relationships and thirdly, we outline what this means for the relationship between buyers and sellers in global markets towards sustainability.

The study aims to analyze consumer reaction to counterintuitive communication linked to the LGBTQIAP+ cause.
Abstract
Purpose
The study aims to analyze consumer reaction to counterintuitive communication linked to the LGBTQIAP+ cause.
Design/methodology/approach
The theoretical framework focused on marketing communication, counterintuitive communication and the insertion of the LGBTQIAP+ issue in them. A hypothetical-deductive approach was adopted, carried out through an online experiment with a factorial design 2 (high involvement product − wedding ring × low involvement − perfume) × 2 (homosexual couple − counterintuitive × heterosexual − intuitive), with two subsequent steps: eye tracker collection (n = 21) and questionnaire application (n = 136).
Findings
It was possible to attest to the differences between traditional (intuitive) and counterintuitive marketing communications, identified both in terms of visualizations and fixations (eye tracking), and objective responses (online questionnaire), finding more positive consumer behavior in the case of counterintuitive communication with insertion of the LGBTQIAP+ cause.
Research limitations/implications
Marketing communication has great potential to create “new/other” values and worldviews, thus having an important role in social responsibility that goes beyond the marketing sphere. Precisely in this context, the study contributes to endorse the literature concerning counterintuitive communication, reinforcing the increasing importance and favorable scenario for its practice, as well as highlighting its importance as an efficient marketing strategy.
Originality/value
The study extends the understanding of counterintuitive communication with the scope of an investigation linked to the LGBTQIAP+ cause, especially from the perspective of the receiving public, the consumers. Furthermore, it advances in the sense of aggregating empirical evidence by means of both exploratory (with neuroscientific technique as eye tracking) and explanatory factors.

Abstract
Purpose
In this paper, the authors contribute with insights on competition and cooperation in multinational enterprises with a focus on challenges related to these governance mechanisms in a knowledge development context. The mechanisms have been widely recognized as important for developing knowledge, but their contradicting nature implies considerable complexity when it comes to governance. The complexity is further increased as a result of the headquarters-subsidiary relationships. The aim of this paper is to contribute with theoretical and empirical insights on these aspects by focusing on the research question: How and why does competition and cooperation in an MNE emerge over time?
Design/methodology/approach
A manufacturing MNE with headquarters (HQ) in Sweden is analyzed on both HQ and subsidiary levels. Interviews with 24 managers in Sweden and India have been performed.
Findings
The study illustrates that competition and cooperation are integral aspects in HQ-subsidiary relationships. The results show that both competition and cooperation depend on environmental, organizational and object-related conditions and that these conditions influence the dynamics of the interplay. The importance of including a subsidiary perspective and the interdependencies in an MNE setting are emphasized.
Originality/value
The authors add to the discussion on the interplay between competition and cooperation as they play an important role for knowledge development in MNEs. The results indicate that they do not take place simultaneously, and therefore, the authors suggest that the dynamic can be better understood by focusing on the interplay and analyze the concepts separately.
