The Sound of a Circular City: Towards a Circularity-Driven Quietness.

The circular economy paradigm can be beneficial for urban sustainability by eliminating waste and pollution, by circulating products and materials and by regenerating nature. Furthermore, under an urban circular development scheme, environmental noise can be designed out. The current noise control policies and actions, undertaken at a source-medium-receiver level, present a linearity with minimum sustainability co-benefits. A circular approach in noise control strategies and in soundscape design could offer numerous ecologically related co-benefits. The global literature documenting the advantages of the implementation of circular economy in cities has highlighted noise mitigation as a given benefit. Research involving circular economy actions such as urban green infrastructure, green walls, sustainable mobility systems and electro-mobility has acknowledged reduced noise levels as a major circularity outcome. In this research paper, we highlight the necessity of a circularity and bioeconomy approach in noise control. To this end, a preliminary experimental noise modeling study was conducted to showcase the acoustic benefits of green walls and electric vehicles in a medium-sized urban area of a Mediterranean island. The results indicate a noise level reduction at 4 dB(A) when simulating the introduction of urban circular development actions.

Revisiting the Concept of Quietness in the Urban Environment-Towards Ecosystems' Health and Human Well-Being.

There is plenty of proof that environmental noise is a major pollutant in the urban environment. Several approaches were successfully applied for its calculation, visualization, prediction and mitigation. The goal of all strategy plans regards its reduction and the creation of quietness. This study aims to revisit the concept of quietness in the urban environment and attempts to portray a new understanding of the specific phenomena. "Quietness" as a term retains an ambiguity, and so far, it can be described as the lack of something, meaning the lack of noise that is portrayed by means of intensity. Several studies describe quietness as the combination of perceptual soundscape elements and contextual factors that can be quantified, combined, weighed and used as indicators of healthy soundscapes. In this research, the focus is on setting aside all indicators, either measuring the intensity or contextual ones and use solely quantifiable metrics regarding the acoustic environment, thus introducing a new composite index called the composite urban quietness index (CUQI). After testing the CUQI, in order to verify the results of previous research regarding the identification of quiet Areas in the city of Mytilene (Lesbos Island, Greece), the study concludes that CUQI is efficiently functioning even in this early stage of development.

Transforming the Future Healthcare Workforce across Europe through Improvement Science Training: A Qualitative Approach.

Healthcare improvement science (HIS) is the generation of knowledge to cultivate change towards improving health systems performance. Our purpose was to evaluate the experience of European nursing students after an intensive one-week summer program conducted in 2019 at the University of Alicante in Spain. The educational intervention combined theoretical and practical HIS contents, with students from different countries, educational programs, and health systems. The intervention was evaluated under a qualitative approach through the open discussion group technique based on the method of participatory action research (PAR), with a total of 25 students who reflected about their experiences and perceptions during the intervention. The responses were used to improve the program's contents, its didactics, and organization. Nursing empowerment, professional recognition, and healthcare research were some of the seven main categories identified through the systematic content analysis method triangulated by three experienced researchers. According to the students' replies, values like compassion, respect, or empathy were identified as key elements of care. Promoting international students' networking emerged as the key to creating a positive provision for change and the generation of improvement initiatives. Building a HIS culture may potentially provide future healthcare professionals with critical thinking skills and the resources needed to improve their future work settings.

Mapping the Status of Healthcare Improvement Science through a Narrative Review in Six European Countries.

With the aim to explore how improvement science is understood, taught, practiced, and its impact on quality healthcare across Europe, the Improvement Science Training for European Healthcare Workers (ISTEW) project "Improvement Science Training for European Healthcare Workers" was funded by the European Commission and integrated by 7 teams from different European countries. As part of the project, a narrative literature review was conducted between 2008 and 2019, including documents in all partners' languages from 26 databases. Data collection and analysis involved a common database. Validation took place through partners' discussions. Referring to healthcare improvement science (HIS), a variety of terms, tools, and techniques were reported with no baseline definition or specific framework. All partner teams were informed about the non-existence of a specific term equivalent to HIS in their mother languages, except for the English-speaking countries. A lack of consensus, regarding the understanding and implementation of HIS into the healthcare and educational contexts was found. Our findings have brought to light the gap existing in HIS within Europe, far from other nations, such as the US, where there is a clearer HIS picture. As a consequence, the authors suggest further developing the standardization of HIS understanding and education in Europe.
