Changes in eating habits and food preferences caused by circadian rhythm disruptions in shift workers increase the risk for chronic diseases. Several studies demonstrated that shift work exerts adverse effects on various risk factors for cardiometabolic disease and cancer. Moreover, shift work leads to altered eating patterns, including diets low in alkaline foods (such as vegetables, fruit and legumes) and high in acidogenic foods (such as meat, fish and cheese). Previously not examined, this imbalance could result in a high dietary acid load (DAL). DAL has been linked to low-grade metabolic acidosis, tissue inflammation and other metabolic alterations. The aim of this study was to investigate the hypothesis that shift work is positively associated with an increased DAL.

The authors used cross-sectional data from the National Health and Nutrition Examination Surveys (2007–2010). The sample for this analysis was drawn from a representative multistage-probability sample of US civilians. DAL estimations included potential renal acid load (PRAL) and net endogenous acid production (NEAP). Acid load scores and nutrient intake were compared between regular day workers (n = 3,814; mean age, 43.7 ± 0.3; mean body mass index (BMI), 28.6 ± 0.1; females 46.9%) and shift workers (n = 881; age, 37.4 ± 0.6; BMI, 28.4 ± 0.3; females 48.1%). Evening/night shift workers combined with rotating shift workers were contrasted to participants on a regular daytime schedule.

Potassium and magnesium intake were significantly lower in shift workers, whereas no significant differences with regard to total energy intake were found. The authors found significantly higher crude NEAP_F scores in shift workers (mean: 61.8 ± 1.2 mEq/day) compared to regular day workers (mean: 58.7 ± 0.5 mEq/day, P = 0.023). After adjustment for confounders, however, this association remained no longer significant. There were no significant intergroup differences regarding NEAP_R and PRAL_R.

This study revealed significant differences in crude NEAP_F scores between shift workers and day workers. After adjustment for confounders, this association was no longer significant. Such discrepancy is probably because of the scarce homogeneity in the analyzed sample which represents the main limitation of this study. Thus, the results did not confirm the hypothesis that shift work is associated with elevated DAL scores. Importantly, the data suggest significant intergroup differences in nutrient intakes without confirming our initial hypothesis with regard to DAL.

In light of the detrimental health outcomes associated with an increased DAL, this study reinforces the call for evidence-based dietary guidelines in shift workers. Studies in other shift working populations are thus warranted.

In this chapter, Andrea Óhidy discusses some pivotal issues of the book. Firstly, she shows the common challenges for current and future EU-member states to increase the participation and success of Roma people in education and lifelong learning. Then she discusses policy strategies and measures for Roma Inclusion in the Western Balkan states Albania, Bosnia and Herzegovina, Kosovo, Montenegro and Serbia. They try to improve the social situation of Roma people but also to promote minority languages and cultures. She found the main cause of the similarities concerning the strategies and concrete projects for possible solutions in the adaptation of the EU Roma inclusion policy in the Western Balkan states as part of their negotiations for EU membership. She considers the implementation of these policy measures and also the educational attainment and success of Roma in the Western Balkans unsatisfactory.

The objective of this study is to examine current business and management research on “Industry 4.0 base technologies” and “business models” to shed light on this vast literature and to point out future research agenda.

The authors conducted a bibliometric analysis of scientific publications based on 482 documents collected from the Scopus database and a co-citation analysis to provide an overview of business model studies related to Industry 4.0 base technologies. After that a qualitative analysis of the articles was also conducted to identify research trends and trajectories.

The results reveal the existence of five research themes: smart products (cluster 1); business model innovation (cluster 2); technological platforms (cluster 3); value creation and appropriation (cluster 4); and digital business models (cluster 5). A qualitative analysis of the articles was also conducted to identify research trends and trajectories.

First, the dataset was collected through Scopus. The authors are aware that other databases, such as Web of Science, can be used to deepen the focus of quantitative bibliometric analysis. Second, the authors based this analysis on the Industry 4.0 base technologies identified by Frank et al. (2019). The authors recognize that Industry 4.0 comprises other technologies beyond IoT, cloud computing, big data and analytics.

Drawing on these analyses, the authors submit a useful baseline for developing Industry 4.0 base technologies and considering their implications for business models.

In this paper, the authors focus their attention on the relationship between technologies underlying the fourth industrial revolution, identified by Frank et al. (2019), and the business model, with a particular focus on the developments that have occurred over the last decade and the authors performed a bibliometric analysis to consider all the burgeoning literature on the topic.

This introduction from Andrea Óhidy and Katalin R. Forray provides a brief overview of the social and educational situation of Roma in the Western Balkan region and the structure of this book. Like in the books Lifelong Learning and the Roma Minority in Central and Eastern Europe (2019) and Lifelong Learning and the Roma Minority in Western and Southern Europe (2020), Roma are here described as a ‘hidden minority’ (Cavioni, 2020, p. 68), because despite the great number and the century-long history of Roma people on the European continent, there is still only limited information and knowledge about them, both in public awareness and scientific research. Although most members of the Roma minority have been living for centuries in their European home countries, their situation is still different from the non-Roma populations: They often suffer from socio-economic disadvantages and hate-motivated harassment and discrimination (EU-FRA, 2020a). This is not only the case in the member-states of the European Union but also in the Western Balkan region. All across Europe, there are Roma groups, which are considered to be the most disadvantaged minority, regarding their health, employment and housing and also in education. To increase their situation, European Union member states have developed common strategies, which play a part in negotiations for an EU-membership status. The so-called Western Balkan states – Albania, Bosnia and Herzegovina, Kosovo, Montenegro, North Macedonia and Serbia – might join the European Union in the coming years. The social inclusion of the Roma minority and the protection of their minority rights in these countries were formulated as a precondition for their application for EU membership. Therefore, several goals, policies and measures were implemented there to break the ‘vicious circle of poverty and discrimination’ (EU-FRA, 2020b). Participation in education and lifelong learning have become central elements of these political measures for Roma Inclusion. This book examines the education situation of Roma across the so-called Western Balkan region.

This study aims to understand what drives firms towards board gender diversity in emerging markets. The authors examine the effect of regulative, normative and cognitive pressures on board gender diversity and the moderating effect of national governance quality.

This study tested the hypotheses using unbalanced panel data for the period between 2014 and 2019, which includes 1,384 observations of 380 different firms located in emerging markets.

The results reveal that board gender diversity is directly conditioned by normative pressures (women’s economic and educational empowerment). This relationship becomes stronger if firms are located in countries with high governance capacity. Interestingly, this study finds that regulative and cognitive pressures do not enhance women’s presence on boards if they are not accompanied by strong national governance.

Although we have learned in recent years about how women’s presence on boards brings positive corporate outcomes, we know little about how country-level antecedents foster or hinder this gender diversity. This paper expands knowledge of the way gender-related institutions affect a firm’s board gender diversity, and these findings have policy implications for firms, policymakers, the government and other institutions.

This study comprehensively depicts the state of the art on sustainability research in the meat supply chain to advance the debate on challenges and issues associated with developing sustainable supply chain management practices.

The authors conducted a systematic literature review of 333 articles published in peer-reviewed journals and organized the extant literature into five areas of supply chain management practices: strategic orientation, continuity, collaboration, risk management, and proactivity.

Since 2016, the meat supply chain has received increasing scholarly attention. The literature shows the diffusion of highly heterogeneous sustainability practices related to multiple management areas and levels of analysis (institutional, industry, firm). The need for integrated, multilevel initiatives involving different stakeholders becomes increasingly crucial to the transition towards more sustainable meat supply chains.

This study highlights the importance of regulatory and stakeholder pressures in the sustainability transition. Beyond setting regulatory requirements, policymakers may facilitate the establishment of collaborations within the meat supply chain and foster the development of support services that help firms to integrate sustainability in their business models. The review also alerts entrepreneurs and managers to the benefits from cooperating with their supply chain partners to navigate the industry transition and thus more effectively respond to the demands of stakeholders and to the increasing customers’ awareness of sustainability issues.

This study is the first to systematize the corpus of knowledge on the sustainability of the meat supply chain by adopting a comprehensive approach to analyze relevant management and agriculture literature.

Process orientation is important for improving organizational performance. The process view is considered a key enabler of digital transformation, and thus management control systems (MCS) are expected to incorporate this view. However, the existing body of knowledge is fragmented, as different process approaches are often considered independently following a reductionist view of control practices. This paper aims to provide recommendations for further research as well as guidance for practice by a systematic review of the state of research of MC for process orientation. It is based on both a comprehensive view to MC using an MCS package approach and a comprehensive view of process orientation.

A systematic literature review addressing major types of process orientation approaches was performed by applying the comprehensive MC framework of Malmi and Brown. The results were synthesized and propositions were developed.

All components of the MC framework, as well as MCS packages, are highly relevant for process orientation. Propositions regarding configurations of MC for process orientation show directions for future research. However, comprehensive considerations of packages and of individual components, especially cultural controls, remain scarce in the literature.

To the best of the authors‘ knowledge, this paper is the first of its kind to provide a comprehensive, structured overview of MC for process orientation, applying a nonreductionist view, based on an MCS Package approach, and consolidating the so far fragmented view of different process approaches.

The purpose of this study is to investigate the structure and dynamics of academic articles relating to public procurement (PP) in the period 1984–2022 (up to May). The researchers also intend to analyse how this knowledge domain has grown since 1984.

A bibliometric analysis was carried out to examine the existing state of PP research. Based on 640 journal articles indexed in the Scopus database and written by 1,247 authors over nearly four decades, a bibliometric analysis was conducted to reveal the intellectual structure of academic works pertaining to PP.

Findings reveal that PP research from Scopus has significantly increased in the past decade. Major journals publishing PP research are International Journal of Procurement Management, Journal of Cleaner Production, Journal of Purchasing and Supply Management and Public Money and Management. Results also indicate that authors’ cooperation network is fragmented, showing limited collaboration among PP researchers. In addition, results suggest that the institutional collaboration network in PP research mirrors what is commonly referred to as the North–South divide, signifying insufficient research collaboration between developed and developing countries’ institutions. According to the co-occurrence keyword network and topic modelling, PP revolves around five main themes, including innovation, corruption, sustainable and green PP, PP contracts and small and medium enterprises. Based on these results, several directions for future research are suggested.

This paper provides an increased understanding of the entire PP field and the potential research directions.

To the best of the authors’ knowledge, this study is the first-ever application of bibliometric techniques and topic modelling to examine the development of PP research since 1984 based on scholarly publications extracted from the Scopus database.

This study aims to analyze the relationship between board gender diversity, board compensation and firm financial performance in the developing country, Jordan, whose cultural, economic and institutional context is very different from most previously analyzed countries’ context.

Ordinary least squares regression was used to examine the association between board gender diversity, board compensation and firm financial performance in a sample of 510 firm-year observations during the years 2009–2018. Generalized least squares estimation method was used to confirm that the results are robust.

The author provides new evidence that board gender diversity does not contribute to firm financial performance. The author also detects that there is a positive relationship between board compensation on firm financial performance.

This paper examines the under-researched relationship between board gender diversity, board compensation and firm financial performance. In so doing, the author tries to provide new insights into this relationship within the developing context, the case of Jordan that has a different environment from that of advanced markets. To the best of the researcher’s knowledge, this is almost certainly the first research to investigate the impact of board gender diversity and board compensation on firm financial performance in the Jordanian market. This manuscript is expected to be used as a reference by the regulators and policymakers – both in Jordan and other countries with a similar institutional, cultural setting – to provide a deep understanding of the impact of board gender diversity and board compensation on the firm performance.

Augmented reality (AR) and virtual reality (VR) are increasingly recognized among technologies potentially driving the digital innovation of small and medium-sized enterprises (SMEs). Nevertheless, the implications of AR/VR adoption in innovation processes have yet to receive much attention to date, with the need to explore the issues facilitating a systematic implementation in the SME context. This study aims to investigate the possible innovation paths of SMEs as a result of AR/VR adoption.

The authors performed a multiple case study research involving six Italian SMEs in manufacturing and service sectors that are investing in AR and/or VR solutions and are digitally innovating thanks to these technologies.

AR/VR solutions lead to different types of innovation in SMEs, i.e. for innovating product or service offerings, business processes or even the business model, when AR/VR extends to the company business logic. SMEs demonstrate being able to leverage internal sources with the essential commitment of top management and low resistance of employees in all kinds of AR/VR-enabled innovations. Conversely, they involve different external innovation sources according to the type of innovation pursued. Organizational issues emerged as more relevant than technological issues.

Results contribute to the literature on digital transformation of SMEs and provide managerial guidance on innovation sources and organizational issues to be considered to effectively deploy AR/VR solutions into specific innovation paths.

This study explores the impact of emergent technologies in the innovation process along with multiple perspectives, degree of complexity, and strategic importance in the SME context.
