(Re)thinking the city of proximity for Salutogenic purposes.

As centres of population and human activities, nowadays urban environments are simultaneously the main cause of and solution to a growing number of health-related challenges. In this setting, COVID-19 pandemic has helped reiterate this and serves as a wake-up call and an opportunity to rethink the way we approach cities. Aim of this paper is to research what today seems the most promising urban model for long-term individual and global resilience: the ‘‘city of proximity’’, namely about inclusive walkable and cycling environments where people can access all basic destinations within reason- able times and distances from home. Therefore, urban proximity dimension, methodological approach and urban features and functions become the main subject of a quanti- qualitative matrix of comparison of five international case studies centred on the topic, by which it is possible to set out general criteria for such model, along with a methodology to measure all cities in its respect. As a result, residential density, functional mix, pedestrian surface, cycle routes, public transport stops, green areas, schools, cultural facilities, sport facilities, retail services and urban gardens make up the fix components of a comprehensive set of 11+n urban features, whose occurrence is investigated through GIS-based analysis within designated distance ranges, creating a comprehensive assessment framework that is adjustable to all urban contexts worldwide. In the end, the application of such framework to the city of Milan finally helps to validate its effectiveness in providing a picture of city-wide accessibility to proximity services, and in highlighting the value of integrated analysis in view of shaping public policies and informed planning choices which put health and sustainability at the centre

Can Homes Affect Well-Being? A Scoping Review among Housing Conditions, Indoor Environmental Quality, and Mental Health Outcomes

The purpose of the scoping review is to explore the relationship between housing conditions, indoor environmental quality (IEQ), and mental health implications on human well-being. In fact, time spent at home increased due to the recent COVID-19 lockdown period, and social-sanitary emergencies are expected to grow due to the urbanization phenomenon. Thus, the role of the physical environment in which we live, study, and work, has become of crucial importance, as the literature has recently highlighted. This scoping review, conducted on the electronic database Scopus, led to the identification of 366 articles. This, after the screening processes based on the inclusion criteria, led to the final inclusion of 31 papers related specifically to the OECD area. The review allowed the identification of five housing conditions [house type, age, and floor level; housing qualities; household composition; neighborhood; green spaces] that, by influencing the IEQ parameters, had impacts on the mental health outcomes addressed. By synthesizing the contributions of the review, a list of design recommendations has been provided. These will serve as a basis for future researchers, from which to develop measures to reduce inequalities in housing by making them healthier, more resilient, and salutogenic

A relativistic positioning system exploiting pulsating sources for navigation across the Solar System and beyond

We introduce an operational approach to the use of pulsating sources, located at spatial infinity, for defining a relativistic positioning and navigation system, based on the use of null four-vectors in a flatMinkowskian spacetime. We describe our approach and discuss the validity of it and of the other approximations we have considered in actual physical situations. As a prototypical case, we show how pulsars can be used to define such a positioning system: the reception of the pulses for a set of different sources whose positions in the sky and periods are assumed to be known allows the determination of the user’s coordinates and spacetime trajectory, in the reference frame where the sources are at rest. In order to confirm the viability of the method, we consider an application example reconstructing the world-line of an idealized Earth in the reference frame of distant pulsars: in particular we have simulated the arrival times of the signals fromfour pulsars at the location of the Parkes radiotelescope in Australia. After pointing out the simplifications we have made, we discuss the accuracy of the method. Eventually, we suggest that the method could actually be used for navigation across the Solar System and be based on artificial sources, rather than pulsars

Measuring the expected increase in cycling in the city of Milan and evaluating the positive effects on the population’s health status: a Community-Based Urban Planning experience

BACKGROUND: It's scientifically known that inactivity is one of the major risk factors for Non-Communicable Diseases. One of the elements affecting the choice of transport mode, regarding circulation in the city, is the cities' urban morphology, i.e. the infrastructural facilities for the slow mobility service. Cyclability, in fact, can help to increase daily physical activity level, therefore becoming a protective factor for individual health. METHODS: After a literature review about the state of the art regarding the correlation between built environment, active transport and quantification of the physical activity level, we have developed a specific questionnaire to collect information about current and forecast use of bicycle, in case of improvement and implementation of the cycling network. The questionnaire also investigated social and health aspects concerning the anamnesis of the interviewees (age, gender, health status, sport activity performed, etc) and users' opinions about existing infrastructure and planned interventions, designed to promote cycling mobility. Aim of the research was to quantify the increase of physical activity people would have realized in front of an improvement of the specific infrastructures, and the expected positive effects in terms of health. RESULTS: The collected data (343 interviewed in a district of Milan, named "Zona 7") demonstrate that through the implementation of the cycle network, there would be more cyclists to practice the 150 minutes weekly of physical activity recommended by WHO: time spent in cycling, indeed, would increases by 34.4% compared to the current level of cyclability, as detected by our survey. CONCLUSIONS: The investigation confirmed that urban interventions, especially those in small-scale, could play a key role in the promotion of healthy lifestyles, inducing therefore important positive effects on the population health. It was also carried out an application of the WHO "Health Economic Assessment Tool" to evaluate the benefits in terms of Non-Communicable Diseases' reduction, specifically a provisional quantification of deaths saved

Explorative Study on Urban Public Space Renovation during COVID-19: Test of a Visual Web-Based Survey about the City of Saint German en Laye, France

Background: The complex socio-epidemiological situation caused by the COVID-19 pandemic forced cities to rapidly adapt to new prevention distancing measures. Several interventions have been made but specific tools are needed to rapidly verify the suitability of such design proposals. This study aims to describe the process of development and testing of a visual web-based survey to assess potential user feedback on Urban Public Space renovation for the city of Saint Germain-En-Laye (SGL), France during the pandemic. The renovation included pedestrianization strategies for the city center and the design and installation of new street furniture. Method: After an exploration of the literature and stakeholder interaction, an online survey composed of three sections and seven questions evaluating the project was developed to rapidly validate the design solution before its actual installation and compare the pre- and post-situation trough visual insights on a 5-point Likert scale. Data was collected through a Google Form and analyzed with descriptive statistics. Results: We received 371 full replies from Italian and French respondents. The survey results showed that the Urban Public Space proposal improved the baseline situation for different reasons, such as safety, sustainability, and accessibility. In fact, Solution A (the existing situation) obtained an average score of 2.08 while Solution B (the design solution) obtained 4.13. Conclusions: The features identified allowed for timely comparisons and possible insights, and the approach can be implemented in other medium-sized European cities dealing with Urban Public Space transformation during COVID-19

Bridging Epidemiological Data with Features of the Urban Context: An experience of Urban Public Health within the City of Milan, Italy.

Referring to the Research Project ‘‘Enhancing Healthcare and Well-Being Through the Potential of Big Data: An Integration of Survey, Administrative, and Open Data to Assess Health Risk in the City of Milan with Data Science’’ the Authors present preliminary results regarding a survey distributed to a sample of citizens across all neighborhoods of Milano city. This survey sought to collect data regarding health risk factors of this population, including both individual (e.g. socio- demographic characteristics, behaviors, etc.) and community (e.g. environmental/morphological features, available social services, etc.) data. A digital survey was designed to collect information on the health conditions, risk factors, and lifestyle characteristics of a representative sample of the Milanese population at the neighborhood level, with reference to the census tracts and Local Identity Units (NIL). Collected survey data are entered into a system containing corresponding individual health information acquired from the Local Health Authority databases, creating a synthesized information profile with each respondent’s state of health, including existing conditions, health services used, and drug therapies. The disseminated survey was developed from comparisons with similar experiences at the national/international level and divided into 60 multiple choice questions (6 for Sociodemographic profile; 8 for Context of residence; 12 for Functional limitations; 25 for Behaviors and lifestyles; 9 for Access to health services). The data from urban analysis conducted on the NIL of the City of Milan are assessed with particular reference to the theme of bicycle-pedestrian accessibility (Walkability) in the urban context and repercus- sions on the adoption of Healthy Lifestyles. The models developed through this research are expected to provide critical insight for designing health promotion, health protec- tion, and disease prevention interventions aimed both at individual and community level
