The quality of 39 guidelines developed locally was assessed, using a standardised instrument addressing five quality domains (scope and purpose, stakeholders involvement, rigour of development, applicability and clarity). For each of them a domain‐specific quality score (ranging from 0 to 100) was estimated. Overall, local guidelines scored particularly low on rigour (mean: 5.1; sd: 12.1) and applicability (mean: 16.9; sd: 12.9). Scores for other domains were only slightly better. This study suggests that local guidelines do not assure neither scientific validity of the recommendations nor attention to their adoption in clinical practice. Without substantial changes in their local use, practice guidelines will not be of any benefit in supporting the implementation of clinical governance.

The purpose of this paper is to provide an analysis of how an airport’s business model (BM) has been innovated. In particular, it considers a BM innovation owing to an exogenous driver, i.e. a change in the legislative environment.

The paper presents an in-depth case study. It analyses the case of an Italian regional airport that has been renewed by changes in the National Plan of Transport.

The paper extends previous research on BM and air transport industry in two ways. First, the authors contribute to Gillen’s (2011) framework, via introducing a new kind of ownership/governance structure, that of long-term concession, characterized by the concession of the comprehensive management to a private company for 30 years. Second, the authors look at how a BM has been implemented and used as a manipulating device over the two phases of the airport development, namely, incubation and generation.

The paper provides an in-depth case study on an airport BM innovation.

The main purpose of this study is to analyze how consumers’ visual attention to wine label design correlates with their preferences. Accordingly, this study uses quantitative eye-tracking metrics to understand which design proposal has greater visual salience. A more specific objective was to assess which design proposal was preferred to be marketed.

The experiment involved evaluating of three different labeling proposals of an Italian winery. Infrared eye-tracking was used to measure implicit eye movements on the three bottles displayed, simultaneously, on a computer screen. A generalized linear model was used to test how consumers' visual attention to wine label design correlated with their preferences.

The design proposals were evaluated significantly differently, with one set being preferred. In general, a strong positive relationship was found between pausing to peruse a specific design proposal and making an explicit choice of the same bottle.

The main limitation of the experiment concerns the sample interviewed. As the sample is homogeneous, the results may not be generalizable to other segments. Furthermore, the addition of electroencephalographic devices that monitor brain activity could provide crucial information for understanding consumer behavior during the purchase decision-making process.

Eye-tracking methods could be useful for designers and wine producers during the evaluation process of design projects.

The use of eye-tracking for evaluating design proposals before placing a product on the market is relatively novel. This method provides objective, quantitative and predictive information on consumer preferences contributing guidelines to designers and marketers during the product conception phase.

Additive manufacturing is today a viable industrial solution alongside traditional processes. Techniques like selective laser sintering (SLS) address the issues of digital production and mass customization in a variety of materials. Composite parts can be obtained with specific functional and mechanical properties. Building orientation during additive manufacturing often causes anisotropy of parts' properties that is still unspecified in technical information. The purpose of this paper is to investigate the mechanical performances and failure mechanisms of an aluminium‐filled polyamide and of a new alumina‐polyamide composite produced by SLS, in comparison with unfilled PA.

A specific focus is set on the evaluation of primary and secondary anisotropy in the case of metal or ceramic filler, as well as on the specific contribution of powder distribution modes and joining phenomena. Macroscopic mechanical tests and the observation of joining and failure micro‐mechanisms are integrated.

The results prove the absence of relevant anisotropy amongst specimens that are produced with the axis parallel to the plane of powder deposition. Samples whose axis is parallel to the growth direction Z, instead, reveal a significantly different response with respect to other orientations.

An original explanatory model is assumed and validated, based on an anisotropic distribution of the reinforcing particles during parts' production, which determines the efficacy of the strengthening mechanisms during crack propagation.

Explores the attitudes of Italian children to money, with reference to US research which indicates a significant difference between boys and girls. Tests five hypotheses relating to gender differences in respect to money: boys are more positive in their attitudes to it, girls would be uncomfortable talking about it, men rather than women are seen by children as economically successful, sons rather than daughters would try to emulate their fathers’ economic status, and these gender differences might increase through adolescence. Explains the methodology of the study, and relates the findings to Italian society and the Catholic religion. Contrasts the attitudes of Italian parents to boys and girls regarding money: boys are more likely to receive regular pocket money and be expected to achieve highly paid jobs, whereas girls tend to value family or more creative activities.

Why are some social movement organizations (SMOs) more likely to participate in coalitions than other SMOs? Drawing on findings from a comparative study of 47 organizations in the women's movement in Buenos Aires, Argentina that were active during the first 20 years of the contemporary democratic period (1983–2003), I examine factors related to participation in coalitions. Using qualitative comparative analysis, I identify three paths for coalition participation that account for 90% of the cases where SMOs participated in coalitions. I find that SMOs cooperated with other groups when they engaged in confrontational protest, when they had broad goals and involved non-members in their work, or when they were inclusive and had a formal division of labor that made it possible to send representatives, as is often necessary in formal coalition work. Along with ethnographic evidence, these findings suggest that scholars should pay more attention to the combinations of organizational factors that influence coalition participation, and the strategic motivations, structural features, and cultural aspects of movement organizations that facilitate cooperation between SMOs.

The purpose of this paper is to report an interdisciplinary, cooperative-learning project in a second-year course within the “Enzo Ferrari” Master of Science Degree in Mechanical Engineering. The work aims to raise awareness of the educational impact of additive manufacturing and reverse engineering.

Students are asked to develop, concurrently, the design and the manufacturing solution for an eye-tracker head mount. A digital head model is reverse engineered from an anatomical mannequin and used as an ergonomic mock-up. The project includes prototype testing and cost analysis. The device is produced using additive manufacturing techniques for hands-on evaluation by the students.

Results of the presented case study substantiate the authors’ belief in the tremendous potential of interdisciplinary project-based learning, relying on innovative technologies to encourage collaboration, motivation and dynamism.

The paper confirms a spreading conviction that the soon-to-be engineers will need new practice-oriented capabilities to cope with new competitive scenarios. Engineering education must adapt to the social, rather than industrial, revolution that is being brought about by additive fabrication.

The purpose of this paper is to evaluate how the direct access to additive manufacturing (AM) systems impacts on education of future mechanical engineers, within a Master’s program at a top Italian University.

A survey is specifically designed to assess the relevance of entry-level AM within the learning environment, as a tool for project development. The survey is distributed anonymously to three consecutive cohorts of students who attended the course of “computer-aided production (CAP)”, within the Master of Science Degree in Mechanical Engineering at Politecnico di Torino. The course includes a practical project, consisting in the design of a polymeric product with multiple components and ending with the production of an assembled prototype. The working assembly is fabricated by the students themselves, who operate a fused deposition modelling (FDM) machine, finish the parts and evaluate assemblability and functionality. The post-course survey covers diverse aspects of the learning process, such as: motivation, knowledge acquisition, new abilities and team-working skills. Responses are analyzed to evaluate students’ perception of the usefulness of additive technologies in learning product design and development. Among the projects, one representative case study is selected and discussed.

Results of the research affirm a positive relationship of access to AM devices to perceived interest, motivation and ease of learning of mechanical engineering. Entry-level additive technologies offer a hands-on experience within academia, fostering the acquisition of technical knowledge.

The survey is distributed to more than 200 students to cover the full population of the CAP course over three academic years. The year the students participated in the CAP course is not tracked because the instructor was the same and there were no administrative differences. For this reason, the survey administration might be a limitation of the current study. In addition to this, no gender distinction is made because historically, the percentage of female students in Mechanical Engineering courses is about 10 per cent or lower. Although the answers to the survey are anonymous, only 37 per cent of the students gave a feedback. Thus, on the one hand, impact assessment is limited to a sample of about one-third of the complete population, but, on the other hand, the anonymity ensures randomization in the sample selection.

Early exposure of forthcoming designers to AM tools can turn into a “think-additive” approach to product design, that is a groundbreaking conception of geometries and product functionalities, leading to the full exploitation of the possibilities offered by additive technologies.

Shared knowledge can act as a springboard for mass adoption of AM processes.

The advantages of adopting AM technologies at different levels of education, for diverse educational purposes and disciplines, are well assessed in the literature. The innovative aspect of this paper is that the impact of AM is evaluated through a feedback coming directly from mechanical engineering students.
