Abstract
Purpose
To provide sufficient conditions for existence, uniqueness and finite element approximability of the solution of time‐harmonic electromagnetic boundary value problems involving metamaterials.
Design/methodology/approach
The objectives are achieved by analysing the most simple conditions under which radiation, scattering and cavity problems are well posed and can be reliably solved by the finite element method. The above “most simple conditions” refer to the hypotheses allowing the exploitation of the simplest mathematical tools dealing with the well posedness of variationally formulated problems, i.e. Lax‐Milgram and first Strang lemmas.
Findings
The results of interest are found to hold true whenever the effective dielectric permittivity is uniformly positive definite on the regions where no losses are modelled in it and, moreover, the effective magnetic permeability is uniformly negative definite on the regions where no losses are modelled in it. The same good features hold true if “positive” is replaced by “negative” and vice versa in the previous sentence.
Research limitations/implications
It is a priori known that more sophisticated mathematical tools, like Fredholm alternative and compactness results, can provide more general results. However this would require a more complicated analysis and could be considered in a future research.
Practical implications
The design of practical devices involving metamaterials requires the use of reliable electromagnetic simulators. The finite element method is shown to be reliable even when metamaterials are involved, provided some simple conditions are satisfied.
Originality/value
For the first time to the best of authors' knowledge a numerical method is shown to be reliable in problems involving metamaterials.

Abstract
From a theoretical point of view the question of spurious modes has been regarded as a closed problem. However, in this paper we show that even a precise definition of spurious‐free approximation was lacking. Hence, a sound definition of spurious‐free finite element method is given and a set of necessary and sufficient conditions ensuring that a finite element method is spurious‐free in the defined sense is stated. A critical comparison between the proposed theory and the currently accepted one is then carried out and existing counterexamples to the latter are pointed out. Comparison with an older theory leads to another set of necessary and sufficient conditions providing a better grasp of the key feature a finite element space must have to rule out spurious modes. The impact of the proposed theory is stressed, showing that Nedelec's tetrahedral edge elements of all orders provide spurious‐free approximations in all conditions of practical interest. Finally, it is shown, for the first time to the best of authors’ knowledge, that also many high‐order edge elements, recently proposed in the engineering literature for the analysis of electromagnetic problems, provide the same kind of reliable approximation.

Abstract
Purpose
Focusing on the adoption of Total Quality Management (TQM) principles in universities, this research paper explores how the “soft” dimensions of TQM trigger its “hard” dimensions considering them at the individual (micro-) and the university (meso-), and eventually at cluster (system-), levels.
Design/methodology/approach
Adopting a qualitative approach, this study presents an in-depth, longitudinal case study of University of Siena, one of the oldest Italian universities, that has been at the core of the research-based cluster on vaccines, today converged in the Tuscan Life Science Cluster. In particular, data were collected between 2018 and February 2022 and consists of archival data (press articles, websites, books), nine interviews to key informants, multiyear experience of the Life Sciences sector by two of the authors and other material put at disposal by university offices, and emails. Data analysis relied on a timeline, a coding procedure that considered three levels of analysis (individual, organization and cluster). Finally, the authors looked at the “how” and “why” the emerged themes have contributed to academic excellence.
Findings
This paper unveils how “soft” and “hard” sides of TQM are blended across multiple levels for reaching academic excellence. The grounded model emerged enlightens the importance of an individual “soft” dimension, academic passion (composed by its three subdimensions of individual research, teaching and entrepreneurial passion) and also sheds light on the organizational “soft” and “hard” sides that the university has been able to design for encouraging research, teaching and third mission quality. Academic excellence has been possible thanks to the capitalization of the individual and organizational “soft” sides into real outcomes as represented by the organizational and individual “hard” sides.
Practical implications
The paper suggests the importance of TQM principles applied at universities' level, providing an in-depth description of “soft” and “hard” sides dimensions of TQM and their impact on all the three pillars of academic excellence. The study findings suggest implications for managers and professionals in the higher education domain as well as for policymakers emphasizing the importance of supporting the individual and organizational soft sides of TQM. The authors provide practical implications recommending universities to consider not only the organizational dimensions but also individual ones when pursuing higher education excellence. In particular, individual passion plays a crucial role and universities need to identify ways of nurturing it. The authors also recommend policymakers to think about new ways to sustain universities as crucial actors in boosting a cluster development, as well as to consider higher education institutions, especially in more rural areas, as a privileged player not only capable of nurturing academic excellence but also able of creating an internationally renowned cluster.
Originality/value
TQM principles have been intensively analysed from an industrial perspective focusing on manufacturing and services, while this paper focuses on TQM in universities, presenting a grounded model that blends the individual and organizational “soft” and “hard” sides.

Abstract
This chapter provides an introduction to the smart city and engages with its idea and ideals from a critical social science perspective. After setting out in brief the emergence of smart cities and current key debates, we note a number of practical, political, and normative questions relating to citizenship, social justice, and the public good that warrant examination. The remainder of the chapter provides an initial framing for engaging with these questions. The first section details the dominant neoliberal conception and enactment of smart cities and how this works to promote the interests of capital and state power and reshape governmentality. We then detail some of the more troubling ethical issues associated with smart city technologies and initiatives. Having set out some of the more troubling aspects of how social relations are produced within smart cities, we then examine how citizens and citizenship have been conceived and operationalized in the smart city to date. We then follow this with a discussion of social justice and the smart city. In the fifth section, we explore the notion of the “right to the smart city” and how this might be used to recast the smart city in emancipatory and empowering ways. Finally, we set out how the book seeks to answer our questions and extend our initial framing, exploring the extent to which the “right to the city” should be a fundamental principle of smart city endeavors.

Abstract
Purpose
In recent years, European banks have been required to integrate environmental and social objectives into their business practices. At the same time, they have become increasingly exposed to environmental, social and governance (ESG) controversies. This paper empirically examines the relationship between the board characteristics of banks (i.e. size, gender diversity, meeting frequency, sustainability compensation incentives and the presence of a sustainability committee) and exposure to ESG-related controversies.
Design/methodology/approach
The empirical analysis focuses on a sample of 61 European banks between 2012 and 2021. Employing generalized method of moments (GMM) estimation, the authors examine the relationship between board characteristics and ESG controversies.
Findings
The results of the study indicate that banks featuring certain board characteristics (i.e. larger and more gender-diverse boards, facing sustainability compensation provisions and having sustainability committees) experience lesser exposure to ESG controversies. Additionally, the authors ascertain that prior instances of ESG controversies play a role in influencing current levels of such controversies. This result highlights the relevance of a bank's historical trajectory.
Research limitations/implications
The authors' sample contains banks based in the European Union (EU). Future research should broaden the analysis to encompass banks operating in other advanced countries, as well as in emerging countries. This expansion would offer more insights into the relationship between board characteristics and ESG controversies under different regulatory frameworks.
Practical implications
The authors' findings provide relevant implications for several stakeholders, including shareholders, regulators and supervisors. Certain board characteristics should be taken into consideration to limit exposure to ESG controversies.
Originality/value
To the best of the authors' knowledge, this paper represents the first attempt to provide evidence of the link between strong corporate governance standards and reduced exposure to ESG controversies.

Abstract
Purpose
This paper aims to investigate whether brand anthropomorphism has a direct impact on brand hate and what are the prevailing factors that play a significant role in this relationship.
Design/methodology/approach
This study provides insights on brand anthropomorphism phenomenon and negative consumer–brand relationships in the context of social media-based anti-brand communities. Using a quantitative analysis of the data gathered from an online survey, this study analyzes brand anthropomorphism in the three main online anti-brand communities toward Apple.
Findings
Findings indicated that brand anthropomorphism in itself does not impact on brand hate directly. Nevertheless, when it is used by consumers to express their negative feelings toward the hatred brand, the consumers’ attribution of responsibility and intentionality to Apple brand’s behavior positively affects brand hate, and ideological incompatibility is a good moderator for brand hate.
Research limitations/implications
The results of this study are based on a limited number of survey respondents because anti-brand community members are very difficult to access, and thus, it was not easy to have their collaboration for this research.
Practical implications
This study highlights the power of social media as a tool for establishing negative consumer–brand relationships. Therefore, brand managers must recognize that consumer activists may be a serious threat to the company and deal with the consumers’ tendency to use anthropomorphism to express their hate.
Originality/value
To the best of the authors’ knowledge, this study is the first to investigate the link between brand anthropomorphism and brand hate, analyzed through a quantitative analysis.

Abstract
Purpose
The paper analyses the influence of the decision-makers' overconfidence on the intuitive practices' adoption, as well as on the international performance during international strategic decision-making processes (SDMPs) of small- and medium-sized enterprises (SMEs). Moreover, the study investigates the possible mediating effect of intuition on the relationship between overconfidence and international performance.
Design/methodology/approach
A semi-structured questionnaire based on a sample of 160 SMEs and a regression analysis have been employed.
Findings
Results show a negative relationship between intuition and international performance and a positive one between overconfidence and international performance. Furthermore, a negative relation between overconfidence and intuition has been identified. Findings also highlight the mediating role of intuition in the relationship between overconfidence and international performance.
Practical implications
The paper provides valuable implications related to the analysis of overconfidence as a critical decision-maker's character and intuition as a feature of the decision-making methodology. Moreover, the study offers indications for SMEs facing complex strategic decisions.
Originality/value
The paper adopts an original perspective by combining the SDMP analysis with that of international strategy within the SMEs context. Additionally, the study enriches the existing literature by (1) investigating overconfidence in the decision-making; (2) enhancing the examination of overconfidence and intuitive practices in the international SDMP; (3) deepening the research field focused on the identification of the intuitive processes' predictors that is still in its infancy.

Abstract
Purpose
This paper aims to provide an analysis of the productivity evolution of a sample of 18,459 knowledge-intensive business services (KIBS) firms operating in Italy over the period 2012–2018. The interaction between productivity heterogeneity firm localization and firm sector of business are also analyzed.
Design/methodology/approach
The empirical setting is based on data envelopment analysis (DEA) to measure the multifactor productivity index (MPI) and on the multilevel models to investigate if the source of productivity heterogeneity among the Italian KIBS are due to the geographic location and/or to the specific business sectors in which firms operate. Data have been gathered from the AIDA database, which contains financial data of all Italian firms.
Findings
The empirical results show that MPI heterogeneity in the Italian KIBS firms' is sensitive to the regional context in which firms operate to the specific KIBS sector and above all at the interactions arising between region and sector.
Originality/value
The paper contributes to identify the source of productivity dispersion in the Italian KIBS.

Abstract
Purpose
Past research on cause-related marketing (CRM) suggests that these socially beneficial initiatives are more effective when linked with hedonic than utilitarian products. Little is known, however, about the process underpinning this effect. This paper aims to investigate why and under what circumstances CRM enhances the appeal of hedonic products by testing the mediation of guilt and introducing the moderating role of cause-product fit.
Design/methodology/approach
The authors test a model of moderated mediation in two studies. Study 1 shows that the effectiveness of combining CRM with hedonic consumption is explained by the mediating role of feelings of guilt. Study 2 demonstrates that this mediation depends on the level of fit or congruency between the cause and the product.
Findings
Results suggest that CRM campaigns offer the opportunity to improve the consumption experiences of hedonic products by reducing the feelings of guilt intrinsically connected with these options. Moreover, fit moderates the emotional processes activated by CRM initiatives. When fit is high, CRM reduces guilt and improves consumers’ experiences when purchasing hedonic alternatives.
Originality/value
The study extends current understanding of how CRM can promote hedonic consumption and contributes further to research on guilt as an emotion able to promote responsible consumption decisions. Moreover, the study introduces and tests the impact of cause-product fit in predicting consumers’ ethical purchase intention. For managers of hedonic brands, the study offers important implications on how to deploy CRM campaigns to foster better customer experiences.
