This paper aims to use Bayesian network (BN) methodology complemented by machine learning (ML) and what-if analysis to investigate the impact of digital technologies (DT) on logistics service quality (LSQ), employing the service quality (SERVQUAL) framework.

Using a sample of 244 Italian firms, this study estimates the probability distributions associated with both DT and SERVQUAL logistics, as well as their interrelationships. Additionally, BN technique enables the application of ML techniques to uncover hidden relationships, as well as a series of what-if analyses to extract more knowledge.

This study was funded by the European Union—NextGenerationEU, in the framework of the GRINS-Growing Resilient, INclusive and Sustainable project (GRINS PE00000018—CUP B43C22000760006). The views and opinions expressed are solely those of the authors and do not necessarily reflect those of the European Union, nor can the European Union be held responsible for them.

This research delves into the influence of DTIE and DTA on SERVQUAL logistics, thereby filling a gap in the existing literature in which no study has explored the intricate relationships between these technologies and SERVQUAL dimensions. Methodologically, we pioneer the integration of BN with ML techniques and what-if analysis, thus exploring innovative techniques to be used in logistics and supply-chain studies.

The purpose of this study is to obtain the optimal frequency for low-frequency transmission lines while minimizing losses and maintaining the voltage stability of low-frequency systems. This study also emphasizes a reduction in calculations based on mathematical approaches.

Telegrapher’s method has been used to reduce large calculations in low-frequency high-voltage alternating current (LF-HVac) lines. The static compensator (STATCOM) has been used to maintain voltage stability. For optimal frequency selection, a modified Jaya algorithm (MJAYA) for optimal load flow analysis was implemented.

The MJAYA algorithm performed better than other conventional algorithms and determined the optimum frequency selection while minimizing losses. Voltage stability was also achieved with the proposed optimal load flow (OLF), and statistical analysis showed that the proposed OLF reduces the frequency deviation and standard error of the LF-HVac lines.

The optimal frequency for LF-HVac lines has been achieved, Telegrapher’s method has been used in OLF, and STATCOM has been used in LF-HVac transmission lines.

This study aims to address the question of what coordination mechanism can be used for cultural production and, in particular, for the governance of music culture production. The authors locate their reflection within the specific institutional innovations introduced in Italy in 2017, focusing on the idea of shared administration and the public–private collaboration instituted in Trentino (a province located in northern Italy) in support of its cultural policy.

This study focusses on the Trentino’s music school system. This includes 13 organisations (musicians’ cooperatives as well as associations of musicians and students, plus one municipal school which do not overlap with the public school system). To analyse shared administration features, the authors rely on selected information from 50 interviews with Trentino Music Schools (TMS) teachers and administrators, and on the proceedings of the 1994 music school conference organised by the schools at the time when this novel educational system was created.

To offer an innovative educational service, the public actor (Provincia Autonoma di Trento [PAT]) and the schools (TMS) have developed a strong interdependence at the different levels of decision-making: PAT needs organisations that are sufficiently structured and organised to respect requirements of transparency and accountability, as well as educational standards, whereas TMS need public funding to maintain their service accessible for users, good labour conditions and be financially sustainable. Likewise, the success of TMS in educating thousands of students every year, including additional teaching programmes funded by PAT within general public schools, has contributed to decrease the exclusion from music education, raise interest in young people for music and fed enrolment in TMS as well as in the public schools related to the conservatoire filière. Conclusions emphasise the existence of a polycentric system of music culture production which needs to acknowledge the risk of being trapped in a static disequilibrium, while recognising change and the need to support and promote a culture of cooperation among schools and across layered institutional levels over time.

Further research can observe this system of cultural production over time, to appreciate changes and organisational tranformations, while introducing comparative analysis with other systems in different regions.

The relationship between the public and private sectors to design, organise and manage activities of collective interest (in the social, cultural, sporting and other fields) can increasingly become an effective and efficient alternative to the traditional bureaucratic as well as to the competitive method. For this to happen, however, all actors involved must be aware not only of areas of efficiency but also of inefficiency. To remedy the latter, corrective measures will have to be introduced. For example, fostering and improving “co-programmazione” and “co-progettazione” means giving all stakeholders involved the opportunity to actively participate. Should the number of participants increase, more discussion fora could be set up because one alone may not be sufficient to foster maximum involvement, to enhance different points of view, to allow for intersectoral and multidisciplinary interpretations and responses.

The system governance based on co-programming and co-design has allowed – despite limitations – to pursue educational purposes and thus well-being for the users, as well as for the teachers and the community as a whole. The continuity of this educational and cultural action has been guaranteed by the economic and financial sustainability of the schools, which is highly dependent on the public actor funding personnel costs, and in turn tied to the number of students (demand) attending each school. Actors embedded in the system need to build awareness of industry and cultural changes and knowledge of how to introduce more adaptive capacity. This points towards the need for strengthening networking capacity and collaboration among schools and other relevant stakeholders.

The case presented is a unique system of music culture production in Italy, and its governance has never been addressed by previous studies. It provides an application of shared administration to which public administrations and communities can learn to improve access to music culture and education. For public and private organisations to take advantage of the method of “co-programmazione” and “co-progettazione”, to make the production of a meritorious good more efficient and to favour its maximum accessibility, this study considers the strengths and weaknesses of this approach, or the areas of efficiency and inefficiency, for which new measures will have to be introduced.
