Abstract
Purpose
Porous implant surface is shown to facilitate bone in-growth and cell attachment, improving overall osteointegration, while providing adequate mechanical integrity. Recently, biodegradable material possessing such superior properties has been the focus with an aim of revolutionizing implant’s design, material and performance. This paper aims to present a comprehensive investigation into the design and development of low elastic modulus porous biodegradable Mg-3Si-5HA composite by mechanical alloying and spark plasma sintering (MA-SPS) technique.
Design/methodology/approach
This paper presents a comprehensive investigation into the design and development of low elastic modulus porous biodegradable Mg-3Si-5HA composite by MA-SPS technique. As the key alloying elements, HA powders with an appropriate proportion weight 5 and 10 are mixed with the base elemental magnesium (Mg) particles to form the composites of potentially variable porosity and mechanical property. The aim is to investigate the performance of the synthesized composites of Mg-3Si together with HA in terms of mechanical integrity hardness and Young’s moduli corrosion resistance and in-vitro bioactivity.
Findings
Mechanical and surface characterization results indicate that alloying of Si leads to the formation of fine Mg2 Si eutectic dense structure, hence increasing hardness while reducing the ductility of the composite. On the other hand, the allying of HA in Mg-3Si matrix leads to the formation of structural porosity (5-13 per cent), thus resulting in low Young’s moduli. It is hypothesized that biocompatible phases formed within the composite enhanced the corrosion performance and bio-mechanical integrity of the composite. The degradation rate of Mg-3Si composite was reduced from 2.05 mm/year to 1.19 mm/year by the alloying of HA elements. Moreover, the fabricated composites showed an excellent bioactivity and offered a channel/interface to MG-63 cells for attachment, proliferation and differentiation.
Originality/value
Overall, the findings suggest that the Mg-3Si-HA composite fabricated by MA and plasma sintering may be considered as a potential biodegradable material for orthopedic application.

Abstract
Purpose
This study aims to contribute to the existing literature by presenting new knowledge about sustainable development goals’ (SDGs) reporting practices through integrated reporting (IR). This paper’s ultimate goal is to dig to light companies’ main approaches to incorporating SDG disclosures into IRs.
Design/methodology/approach
This study puts forward both deductive content analysis and an inductive thematic analysis on a sample of worldwide leading IR adopters to assess what SDGs they disclose and how they integrate SDGs into the reports. Meaningful narratives and graphical illustrations are selected, categorised and discussed from a symbolic/substantive legitimacy perspective.
Findings
The results of this study highlighted that although a fair number of leading IR adopters addressed SDG issues, their pathways to disclosure were not uniform. In some cases, SDGs inspired substantive changes to internal management and process, communicated through an integrated approach. However, there was a persistent trend of using SDGs as camouflage and symbolic tool to enhance company’s reputation and obtain a licence to operate.
Originality/value
To the best of the authors’ knowledge, this was the first study that performed a deductive/inductive thematic analysis to engender insight into the most meaningful patterns followed by leading IR reporters worldwide to disclose their contributions to SDGs and address their legitimacy.

The study aims to examine the impact of corporate governance in terms of certain board characteristics on the level of universities’ voluntary sustainability disclosure.
Abstract
Purpose
The study aims to examine the impact of corporate governance in terms of certain board characteristics on the level of universities’ voluntary sustainability disclosure.
Design/methodology/approach
A content analysis based on a comprehensive disclosure index – that also accounts for the impact that COVID-19 exerted on the social dimension of university activities – is performed on a sample of Italian public universities’ websites for the year 2020. An ordinary least squares regression model is estimated to test the association between universities’ board characteristics, namely, board size, board independence and board gender diversity (including the presence of a female rector), and online sustainability disclosure.
Findings
This study provides evidence that websites represent a valid tool used by universities to highlight their social performance and demonstrate their commitment to dealing with the pandemic’s social and economic disruption by supporting their stakeholders. Board gender diversity and female Rector’s presence are crucial factors that positively impact voluntary sustainability disclosure levels.
Practical implications
Policymakers and regulators can benefit from the study’s findings. Using the results of this study, they may reflect on the need to regulate sustainability reporting in universities. In addition, findings may offer policymakers inspiration for regulating the presence of women on university boards.
Originality/value
This study offers novel contributions to existing literature analysing the university’s voluntary sustainability disclosure practices through alternative communication tools such as websites. Moreover, it provides novel insight into the role of the board gender diversity in university sustainability disclosure practices.

Abstract
Purpose
This paper explores total quality management (TQM) soft domain efficacy in social care organizations to determine the extent to which an organization's project success may stem from soft TQM critical success factors (CSFs).
Design/methodology/approach
Non-structured interviews were conducted with 16 managers overseeing the prosthetic device regeneration project of the Italian local health unit (located in Salerno) to explore which soft factors could contribute to the success of a social care multifunctional organization.
Findings
Organizations' handling of certain projects, such as pivoting on soft TQM issues, may allow them to be configured as multiservice organizations. Therefore, a conceptual model of a multiservice social care organization is proposed.
Practical implications
From a managerial perspective, this study presents an interesting success case of a multiservice social care organization with a total annual expenditure of €20 million on prosthetic assistance. Preliminary data show a 13% reduction in public expenditure for Salerno's local health unit via a refurbishment project.
Originality/value
The paper contributes to the soft TQM literature debate: although Italian local health professionals appear aware of soft TQM issues' implementation and consciously apply them in their organization and projects, this occurs more with specific CSFs emerging from the literature. Therefore, this article paves the way for further quantitative and theoretical investigations on the adoption of TQM soft issues in social care organizations' performance measurement.

Abstract
Purpose
The present study aims to extend the knowledge of intellectual capital disclosure (ICD) disclosure practices in the Italian Healthcare Organisations (HCOs) context. The ultimate goal of the study is to provide fresh insight into the possible explanatory factors that may drive the extent of ICD provided by Italian HCOs via the web.
Design/methodology/approach
The present study applies a manual content analysis on the websites of a sample of 158 HCOs to determine the level of voluntary ICD. A multivariate regression model is estimated to test the association between different variables – size, gender diversity in top governance positions, financial performance and indebtedness – and the level of ICD provided by sampled HCOs through their official websites.
Findings
Content analysis results reveal that – in the absence of mandatory requirements – Italian HCOs tend to use websites to disclose information about IC. Particular attention is devoted to Structural and Relational Capital. The statistical analysis pinpoints that size and indebtedness negatively influence the level of ICD. In contrast, the presence of a female General Manager (GM) positively drives ICD. Also, it is observed that Research and University HCOs and those located in the Italian Northern Regions are particularly prone to discharge accountability on IC through websites.
Originality/value
To the best of the authors’ knowledge, this is the first study that examines voluntary ICD practices through websites in the Italian HCOs' context. Also, since prior studies on IC in the healthcare context are mainly descriptive or normative, this is the first study examining the potential determinants of ICD provided by HCOs in terms of size, gender diversity in top governance positions, financial performance and indebtedness.

Abstract
Purpose
This paper aims to review recent literature results on the mechanical response of confined pentamode structures behaving either in the stretching-dominated or the bending-dominated regimes.
Design/methodology/approach
The analyzed structures consist of multilayer systems formed by pentamode lattices alternated with stiffening plates and are equipped with rigid or hinged connections.
Findings
It is shown that such structures are able to carry unidirectional compressive loads with sufficiently high stiffness, while showing markedly low stiffness against shear loads. In particular, their shear stiffness may approach zero in the stretching-dominated regime.
Originality/value
The presented results highlight the high engineering potential of laminated pentamode metamaterials as novel isolation devices to be used for the protection of buildings against shear waves.

Abstract
Purpose
This paper aims to explore how the Italian wine industry discloses corporate social responsibility (CSR) practices and quality certifications and the corresponding determinants via websites. The study also aims to investigate the relationship between CSR practices and financial performance. The information consistency between the quality certificates reported on corporate websites and official database statements is also explored. Lastly, the paper investigates how the relationship between the size of wineries and CSR disclosure changes according to firms' geographic location.
Design/methodology/approach
This paper analyses CSR corporate communication via the websites of a sample of Italian wineries by adjusting the theoretical framework developed by Amran (2012) to the wine sector's peculiarities. Moreover, a cross-certification analysis and a moderation analysis were performed to fulfil the purpose of the research.
Findings
The analysis revealed the extensive use of CSR disclosure via websites. It was found that company size positively affects CSR disclosure and Quality Certification Disclosure (QCD), while geographic location slightly moderates the relationship between the two variables. In addition, a negative relationship between CSR disclosure and corporate financial performance and its reverse causality emerged. Moreover, for most wineries, information consistency between the quality certificates reported on corporate websites and official database statements was observed.
Research limitations/implications
The study's main limitation is that the search process was performed during lockdown. Therefore, the examined issues could change in the near future due to the shift in priorities that the COVID-19 pandemic is determining.
Practical implications
The results can help managers implement CSR disclosure and QCD practices to enhance stakeholder legitimacy and enable their companies to compete in strongly competitive international markets.
Originality/value
The paper represents the first study investigating online QCD and its consistency in the Italian wine sector.

Abstract
Purpose
This paper investigates the extent to which the COVID-19 pandemic has accelerated service innovation in the restaurant sector. It explores the use of digital technologies (DT) as a safety-empowerment and resilient strategy in the food-service industry during the pandemic. It also investigates the impact of DT on customers' risk perception (CRP) and customers' intention to go to restaurants (CIR) in Italy.
Design/methodology/approach
Based on the theory of planned behaviour and perceived risk theory, this study investigates a sample of customers residing in Italy. Multiple regression and mediation analyses are conducted to test the research hypotheses, adapting the logic model developed. Using the bootstrapping technique, this study also explores whether the pandemic has moderated the relationship among several variables adapted from the literature. Robustness tests are also performed to corroborate the analysis.
Findings
The pandemic has accelerated the food-service industry's digital transformation, forcing restauranteurs to implement DT to survive. Findings show that DT support restauranteurs in implementing innovative services that reduce interactions and empower cleanliness among workers and customers, reducing CRP and preserving CIR. Thus, managing risk perception is helping the restaurant sector to recover.
Practical implications
Practical implications are presented for policymakers to catalyse the digital transformation in small- and medium-sized restaurants. The results may also be beneficial for entrepreneurs who can implement innovative service practices in order to reduce interaction and empower cleanliness levels. Moreover, academics can use these results to conduct similar research in other geographical contexts.
Originality/value
The present research represents the first study investigating the relationship between the use of digital technologies and the intentions of customers to go out for dinner during the ongoing pandemic in Italy.

Abstract
Purpose
In the era of artificial intelligence, natural language processing (NLP) models are revolutionizing numerous sectors. This research aims to explore the perceived value of them among university students. In particular, it aims to investigate how gender may influence students’ intention to use these models in educational contexts, highlighting potentially significant differences that could inform the implementation and adoption of educational technologies.
Design/methodology/approach
This study investigates the relationship between perceived value and students' intention to adopt NLP models, considering gender as a moderator. The research involves 562 students from the University of Salerno, in Italy, and uses confirmatory factor analysis to evaluate the reliability and validity of the measurement scales. A regression model with robust errors is used to explore the moderating role of gender on the relationship between perceived value and intentions of use of NLP models.
Findings
The results reveal a significant positive association between perceived value and intention to use NLP models, confirming that students with higher perceived value are more likely to adopt these technologies. Furthermore, gender moderates this relationship, indicating that females are less prone to use NLP models than male counterparts.
Originality/value
Research takes on a significant role in the academic field, underlining the importance of adapting teaching practices to the increasingly widespread digitalization. The inclusion of NLP models in university programs emerges as a possible improvement of the learning experience, ensuring cutting-edge education in tune with the needs of the digital society.

Abstract
Purpose
This study intends to analyze the relationship between the digital maturity of SMEs and intellectual capital, investigating the determining factors. Starting from the endowment in terms of intellectual capital and evaluating Management Style, Decision-Making Competences, and Business Network, a model is proposed aiming to provide a comprehensive measure of SMEs’ digital maturity and thus to improve understanding and, consequently, effectiveness. The empirical analysis allows assessing the validity and applicability of the suggested model, providing valuable insights for the improvement of digital strategy and competitiveness of SMEs in the Amalfi Coast Tourist District (Italy), with evident implications also for policymakers and the community.
Design/methodology/approach
A mixed-methods research strategy was utilized to confirm research hypotheses that were derived from literature review. The field study was organized into two separate phases: the first phase, which is qualitative, employed focus groups comprising key stakeholders (managers and entrepreneurs) from various companies within the Amalfi Coast Tourist District. This phase adhered to the principles of homogeneity (to facilitate deeper discussions) and heterogeneity (to allow for a broader range of viewpoints among participants). The insights gathered from these preliminary focus groups informed the subsequent quantitative phase. In this second phase, structured interviews were conducted using a questionnaire to probe the participants’ views on digital maturity. This analysis involved 94 companies, all part of the Amalfi Coast Tourist District, assessing their digitalization levels and highlighting key management attributes. Logistic regression was applied to quantitatively analyze the data, effectively assessing the impact of various independent variables (such as Management Style, Decision-Making Competencies and Business Network) on the dependent variable, digital maturity. Employing both qualitative and quantitative methods provides a thorough and nuanced understanding of the digital maturity landscape within the specified context.
Findings
The main results suggest the existence of a correlation between the analyzed variables and digital maturity. Innovation, indeed, increases by applying a data-driven leadership style. Intellectual capital (measured in its three components of human capital: decision-making competences; structural capital: management style; and relational capital: business network) influences digital maturity, although some of the variables used are not equally weighted.
Originality/value
The main contribution of this article is to provide an in-depth understanding of the company components that favor digital maturity, to support strategic choices oriented towards a conscious digital transition. The results enrich the existing literature on intellectual capital in terms of its contribution to the digitalization of organizations, which can be a critical success factor in the context of SMEs.
